How to Maintain a Healthy Lawn in Raleigh’s Climate
Raleigh ProConnect- April 22, 2025
Building and maintaining a healthy lawn in Raleigh doesn’t require you to be a lawn expert. It’s more about doing the right things at the right time. With dense clay soil, humid summers, and the occasional surprise drought, success comes down to understanding your soil, choosing the right grass for your property, and creating a care routine that works with Raleigh’s climate.
There’s nothing quite like walking barefoot across a thick, green lawn in Raleigh. It’s the closest thing you’ll get to an outdoor carpet. It’s soft, cool, and has just the right amount of give under your feet.
But of course, not every lawn looks (or feels) like that.
Some yards are a patchy mix of bare spots and finger grasses. Others look like they’ve evolved into a local Burning Man festival, complete with fire ant mounds everywhere.
…Not exactly the type of yard that’s the envy of the neighborhood.
If you’ve lived in Raleigh for a while, you already know you can expect everything from muggy heat waves, mild winters, and sudden droughts that show up just when your grass is starting to look halfway decent.
And if you’re new here, you might be wondering why your red soil feels more like concrete than the loose, rich dirt you were hoping for.
The challenges homeowners deal with in Wake County are pretty specific. Our hot, humid summers create perfect conditions for fungal diseases like brown patch and dollar spot. Then you’ve got grubs and chinch bugs showing up like they’ve just been waiting for the perfect time to take over.
Add in the seasonal stress on different grass types, and weeds like crabgrass, chickweed, or ragweed that keep trying to take over no matter what you do, and it’s easy to feel like you’re fighting an uphill battle.
Maintaining a healthy lawn in Raleigh’s climate takes some work. That part’s true. But you’re here, so that means you’re already willing to put in the effort.
The real challenge is figuring out what’s best for your yard:
- What is your soil trying to tell you?
- What kind of grass actually belongs there?
- How to manage moisture and drainage
It’s a series of small, smart choices. Things like making sure you’re watering at the right time, knowing when to fertilize (and when not to), picking the right grass type based on the amount of sun or shade your lawn receives, and working with the seasons, not against them.
Whether you’re managing a few hundred square feet of established turf or starting from scratch and staring at compacted clay across your entire yard, success starts below the surface.
In this guide, we’ll walk through the steps that actually matter. We’ll cover everything from soil testing and proper mowing to pest control and seasonal fertilization, so you can build a lawn that not only survives Raleigh’s crazy weather but flourishes in it.
Understanding Raleigh’s Growing Conditions
Before you put down any seed or break out the fertilizer, the first step in lawn maintenance is understanding the conditions you’re working with.
Raleigh sits in USDA Hardiness Zones 7b to 8a, which puts it right in the “transition zone”. This is a tricky area where neither cool-season nor warm-season grasses dominate year-round.
That’s why building a beautiful lawn in this region starts with making the right choices based on your yard’s unique needs. Soil health, grass selection, and proper timing all play a role.
In the following sections, we’ll break down how to prepare your soil, choose the right grass for your lawn’s conditions, and establish it in a way that sets you up for long-term success.

Soil Preparation & Correction
Much of the Triangle region sits on Piedmont clay. This is a dense and acidic soil type that’s naturally compacted and doesn’t drain well. If you’ve ever tried to dig in your yard and hurt your wrist, you know what I’m talking about.
When it’s left untreated, it holds water where it shouldn’t, repels water where it’s needed, and makes it difficult for grass roots to establish.
That’s why soil testing is one of the most important first steps you can take in lawn maintenance. Most people skip this step, but if you truly want a healthy lawn, it’s not optional.
Soil Testing
All you have to do is send a sample to the NC Cooperative Extension (tests are free most of the year), and within a few weeks, you’ll receive a detailed report with:
- Information about your soil pH
- Levels of major plant nutrients (including phosphorus, potassium, calcium, magnesium and sulfur)
- Levels of plant micronutrients (including copper, manganese and zinc)
- Levels of sodium
- Soil class
- Percent base saturation
- Percent humic matter
- Cation exchange capacity
- Weight-to-volume ratio
Based on those results, you’ll know whether you need to add lime to raise the pH or sulfur to lower it, instead of just guessing and hoping for the best. This is the only way you’ll be able to bring your soil into balance.
Improving Your Soil Structure
After the test, your next step is to improve the soil structure. This is especially helpful for small lawns or areas that stay soggy or struggle with poor drainage.
Add organic matter, like compost, aged pine bark fines, or well-rotted leaf mulch, to break up the clay and create air pockets that allow water and roots to move through the soil.
A richer, more aerated soil mixture promotes stronger root growth and reduces the risk of runoff during those heavy summer rains we get.
If you’re starting fresh or renovating part of your lawn, don’t skip grading it. The surface of your lawn should gently slope away from your home to prevent water from pooling.
Low spots where water collects will eventually lead to dead patches, make the area more susceptible to pests, and can lead to fungal growth. Use topsoil or a clay and compost blend to establish a smooth, even grade across the lawn.
This process takes some effort, but it lays the foundation for everything else. If the soil isn’t right, there’s no amount of watering, mowing, or fertilizing you can do that will give you the results you’re after.
Take the time to get it right now, and you’ll have fewer problems later and better growth all season long.
Grass Type
Once your soil’s ready, it’s time to pick the right grass. And I say right grass here because choosing the wrong type is an easy way to lose time, money, and your sanity.
Since Raleigh sits in the transition zone, you’re not limited to just one kind of grass.
But if you want a green lawn that holds up through the random ups and downs of the seasons, you’ll need to match the grass type to your yard’s specific conditions. Things like shade levels, drainage, and the amount of foot traffic your lawn gets should all be taken into account.
You’ll also want to think about how much maintenance you’re realistically willing to take on. Some grasses grow quickly and need frequent mowing, while others are slower, more laid-back, and better suited for homeowners who want less to manage.
So, what types of grass work best around here?
Hybrid Bermudagrass, Zoysia, Tall Fescue, and Centipedegrass are the most popular and reliable options for homeowners in Wake County. But you’ll also come across lawns with St. Augustine, Kentucky Bluegrass, and Perennial Ryegrass. Each of these grasses comes with its own pros and cons.
Here’s a breakdown of how they perform:
Warm-Season Grasses
These do best in Raleigh’s hot, humid summers and go dormant once temperatures drop in late fall or early winter.
- Bermuda loves full sun and handles Raleigh’s extreme summer temperatures well. However, it requires frequent mowing and is prone to thatch accumulation if not managed properly.
- Zoysia is more drought-tolerant and provides dense coverage, which makes it great for crowding out weeds and invasive plants. It’s slower to establish and green up in the spring, but it offers a cushiony texture and a durable lawn surface. If you’re patient and consistent, it pays off.
- Centipedegrass is low-maintenance and slow-growing. It prefers acidic soil (which Raleigh has plenty of) and does best in full sun. It’s not as tough under heavy foot traffic, but great for homeowners who want something easy to manage.
- St. Augustine is a shade-tolerant warm-season option that works in humid environments. Its thick blades present a lush appearance, but it’s more susceptible to damage from cold weather and certain pests like chinch bugs, so it’s a bit higher maintenance than Centipede or Zoysia.
Best time to plant (sod, sprigs, or plugs): Late April through June, once soil temperatures hit 65°F or higher. That’s when warm-season grass roots really take off.
Cool-Season Grasses
These are great for shady areas or if you want your lawn to stay greener later into the year.
- Tall Fescue is one of the most versatile options for this area. It can handle sun, shade, and summer temperatures better than most cool-season grasses, though it’ll need more watering in the hotter months.
- Kentucky Bluegrass has a beautiful, fine texture and spreads by underground rhizomes, which helps it recover nicely from wear. However, it doesn’t tolerate Raleigh’s heat as well as Tall Fescue and may struggle during long, dry summers unless carefully managed.
- Perennial Ryegrass germinates fast and has a bright, attractive color. This is mostly used in more Northern states, but some homeowners will overseed their warm-season grass with this to keep their yard green in the winter. It’s not well-suited for summer on its own in this region, but it can be helpful for temporary coverage.
Best time to seed or overseed: Mid-September through mid-October, when nighttime temps start dipping near 60°F. That gives the roots a chance to establish before winter dormancy.
Seeding, Sodding & That First Year
Whether you’re putting in a new lawn or filling in dead patches, how you plant matters.
- Sod establishes faster and gives you an instant lawn, but it’s more expensive upfront. It’s typically the best way to establish Bermuda, Zoysia, St. Augustine, or Centipedegrass, especially if you want quick results and fewer weeds early on.
- Grass seed is more budget-friendly and works especially well for Tall Fescue, Ryegrass, or Bluegrass blends, especially in the fall during Raleigh’s optimal overseeding window.
Once the grass is in, stick with light, frequent watering. You want to give your lawn just enough water to keep the soil moist until the roots establish.
When you get those roots well established, your lawn becomes more resilient. It’ll be able to bounce back from droughts faster, you’ll deal with fewer weeds, and you’ll have a stronger lawn that can hold up against pest problems and diseases.
And don’t mow too early. You want to wait until the grass is about one-third taller than your target height, which we’ll discuss in more detail later.
How to Maintain a Healthy Lawn
Once your lawn is established, keeping it healthy comes down to consistency and timing. You don’t need a binder full of plans or a shed full of products. You just need to know what your grass actually needs, and when it needs it.
That means watering the right way, mowing at the right time and height, feeding with purpose, and staying ahead of any problem areas before they spread.
A few good lawn habits can go a long way, and this section walks you through the ones that matter most.
Watering Strategy
If there’s one part of lawn care that can get complicated, it’s watering. Too much, and you’re asking for diseases. But water too little, and your lawn gets crispy by July.
Once your lawn has established, it typically only needs about one inch of water per week. This includes any rainfall that’s already happened or that’s expected. That’s enough to soak the soil down to the root zone, which will encourage deeper root growth and help your lawn ride out the next dry stretch without going into stress.
When watering, your goal should be to water deeply once or twice a week, rather than light watering every day.
Note: Use a rain gauge or a tuna can to measure how much water your lawn is actually getting. To do this, turn on your sprinklers and time how long it takes to collect half an inch (half the tuna can). This amount of time becomes your standard watering session if there is no rainfall in the forecast. Run your system for that long, twice a week, to give your lawn the one inch of water it needs each week.
New lawns are the exception. These need a different approach until roots get established. You want to keep the top layer of soil moist with light, frequent watering until the grass roots start to establish at first, then gradually transition to deeper, less frequent watering as your lawn matures. Use the chart below as a guide:
Watering Guide for New and Established Lawns
| Lawn Stage | Frequency | Amount | Goal |
| Germination | 2–4 times per day (5–10 mins each) | Light misting, keep top 1–2" moist | Keep the surface consistently damp to support seed germination. |
| Early Growth | 1–2 times per day (15–30 mins each) | Moist soil to 4–6" depth | Begin deepening moisture to promote root anchoring. |
| Rooting Stage | Every other day or 2–3x/week | About ½ inch per session | Reach 6–8" soil depth to encourage deeper root development. |
| Established Lawn | 1–2 times per week | About 1/2 inch per session, totaling to 1" per week (including rainfall) | Maintain strong root systems and improve drought tolerance. |
Watch how your soil takes the water. If water starts pooling up in certain areas around your yard, split up your watering into shorter cycles for these spots. This should help the water soak in instead of evaporating or running off.
The Time of Day You Water Matters Too
The best time to water your lawn is early in the morning between sunrise and 9 a.m.
Why?
Because this gives the water time to soak into the soil before the sun gets too strong and starts to evaporate it. If you water later in the day or in the evening, you run the risk of your lawn staying wet overnight, which is how lawn diseases start.
Adjusting Your Watering for Droughts & Raleigh’s Summer Weather
Raleigh averages around 46.58 inches of rainfall per year, but summers can still bring the possibility of dry stretches and water restrictions.
When drought advisories are in place (which Wake County sometimes enforces in stages), switch to survival watering and give your lawn about ½ inch of water every two to three weeks.
This amount is just enough to keep the grass crowns (the part just above the roots where new growth comes from) alive until conditions improve.
At this point, you’re not trying to keep your lawn green. You’re just trying to prevent permanent damage. The grass might turn brown on top, but if the roots are alive, it’ll bounce back when rain returns.
Watering your lawn correctly gives it a huge advantage during those long, hot North Carolina summers where every drop counts.
Mowing Practices
If you’re doing everything else right but mowing wrong, your lawn will still struggle. Cutting your grass too short, using dull blades, or not mowing it at the right time can introduce pests, diseases, and allow weeds to overtake it.
Let’s start with the grass height, because this is probably the most important thing you need to get right.
Each grass type has its own “sweet spot” or an ideal height range that keeps it healthy, dense, and better protected from heat, drought, and thatch accumulation.
Cutting your grass too low, or scalping it, can weaken the lawn, expose the soil, and force the grass to use all its energy just trying to recover.
On the other hand, if you let your grass grow too tall, it starts to shade itself, which prevents the lower parts of the grass from getting the sunlight and airflow they need.
This can lead to weak, thin growth and increases the risk of disease by trapping moisture. Not to mention, when you finally do mow, you’re removing too much at once, which shocks the roots.
But if you get it right, then everything else (watering, fertilizing, and weed control) works a lot better and is easier to manage.
Here’s a cheat sheet for the different mowing heights based on the type of grass you’re most likely growing in Raleigh:
Note: The heights below are measured from the mower blade to a firm, level surface. These ranges are based on ideal growth conditions in Raleigh, NC, and assume the grass is actively growing. Your exact mowing height and schedule may vary slightly depending on weather, shade, and soil conditions.
Mowing Height & Frequency Guide by Grass Type
| Grass Type | Recommended Mowing Height | Mow When it Reaches This Height | Mowing Schedule | Specific Notes |
| Bermudagrass | 1 to 1½ inches | 1⅓ to 2 inches | Every 3–5 days during active growth (summer). | Maintain a shorter height for best density and to minimize thatch accumulation. Frequent mowing keeps it healthy and vibrant. |
| Zoysia | 1½ to 2½ inches | 2 to 3⅓ inches | Every 7–10 days during peak season. | Doesn’t grow tall very fast. Can be mowed at 1 to 1½ inches between January and April. |
| Tall Fescue | 3 to 4 inches | 4 to 5⅓ inches | Weekly in spring and fall; every 7–14 days in summer. | The extra height improves drought and shade tolerance. Maintain 4 inches during the summer. |
| Centipedegrass | 1½ to 2 inches | 2 to 2⅔ inches | Every 7–14 days during the growing season. | Keep at recommended height to protect its shallow roots. Shorter cuts can severely weaken it. |
| St. Augustine | 2½ to 4 inches | 3⅓ to 5⅓ inches | Every 5–7 days during active summer months. | Requires taller mowing to maintain thick growth, discourage chinch bugs, and increase its tolerance to heat stress. |
| Kentucky Bluegrass | 2½ to 3½ inches | 3⅓ to 4⅔ inches | Every 5–7 days in the Spring and Fall; Every 7–10 days during Summer. | Benefits from seasonal adjustment: slightly taller in summer to shield roots from heat, shorter in spring and fall to help it grow in thicker. |
| Perennial Ryegrass | 1½ to 2½ inches | 2 to 3⅓ inches | Every 5–7 days during peak growth periods. | Fast-growing; best kept shorter to maintain a neat appearance. When mixed with warm-season grasses, adjust height to match. |
Other Mowing Tips
Here are a few more mowing tips worth remembering:
- Never remove more than one-third of the grass blade length in a single mowing.
If you’ve scalped your lawn, give it time to recover to the height shown in the table above. But don’t try to fix it all in one cut. Gradually lower your mower height over multiple mowings. - Keep your mower blades sharp.
Sharpen blades before the mowing season starts, then maintain a schedule of sharpening every 8–12 hours of mowing. Dull blades tear the grass instead of cutting it cleanly, leaving ragged edges that cause your grass to lose moisture. If you’re seeing brown tips on your grass after mowing, your blades probably need to be sharpened. - Try to mow at the right time of day.
The best times to mow are mid-morning (8-10 a.m.) or early evening (4-6 p.m.), when temperatures are cooler and the grass is dry. Avoid mowing in the middle of the day, as the heat can stress the grass and reduce its ability to recover. If your lawn is drought-stressed, it’s ok to mow when dew is still present, but be careful, as wet grass doesn’t cut evenly, and leftover clumps can smother your lawn and spread disease. Always try to mow when the grass is as dry as possible for the cleanest cut and healthiest lawn. - Change your mowing pattern each week.
This helps prevent ruts, soil compaction, and encourages upright growth. Alternate between horizontal, vertical, and diagonal paths on a weekly basis. - Leave the clippings (as long as they’re not smothering the lawn).
Grasscycling returns up to 25 percent of your lawn’s total fertilizer needs and can provide up to 1 lb of nitrogen per 1,000 square feet each year. Make sure to rake out any clumps thicker than one inch. - Adjust your mowing schedule for the seasons.
If you’re using a cool-season grass, raise your mower height in summer. For warm-season grasses, lower the height slightly in fall to prevent thatch buildup. - Keep your mower deck clean.
Old grass clippings and other debris tucked under the deck can retain moisture, which can create diseases that eventually spread to your lawn. The buildup can also dull your mower blades more quickly, resulting in ragged cuts. Rinse the deck off with a hose when you’re done.
Getting your mowing schedule dialed in is one of the easiest ways to maintain a clean and healthy lawn over time. When done right, it supports root health, reduces stress, and keeps everything growing the way it should throughout the year.
Fertilization Calendar for North Carolina Lawns
Fertilization is where a lot of people either overdo it, use the wrong product at the wrong time, or skip over the most important times of year when their lawn will actually benefit from it.
You don’t want to just throw down whatever bag is on sale at the hardware store. Each type of grass responds differently to fertilizer.
Some are light feeders, and some need all the help they can get to push through the summer heat. Others just want to be left alone completely.
Your timing, the type of fertilizer you use, and how much you put down all need to line up correctly with your grass species. If you can get this part right, it’ll make a big difference in the overall health of your lawn.
Below is a breakdown of what your lawn needs, when to apply it, and how much to use based on North Carolina’s climate and grass type:
Bermudagrass
Type: Warm-season
Feeding Level: Moderate to heavy
Fertilizer Type: High-nitrogen or balanced, slow-release preferred
Bermuda loves to grow, but that can mean rapid thatch buildup if you overfeed or skip mowing. Stick with spoon-feeding and mow regularly to keep it in check.
When & How Much:
| Timing | Nutrient Focus | Application Rate (per 1,000 sq ft) | Notes |
| Late April or early May | Nitrogen (N) | 0.5 – 1 lb | Begin applications 2 to 3 weeks after full green-up. Avoid early spring fertilization to prevent frost damage. |
| June to August | Nitrogen (N) | Up to 1½ lbs total | Split into smaller doses every 4–6 weeks; add iron if the color fades without new growth |
| September to November | Low Nitrogen (N), Potassium (K) | ≤ 0.5 lb N + 1 lb K₂O | Optional light feeding only if the lawn is still actively growing. Apply potassium to strengthen roots and prepare for dormancy. |
| December to February | None | None | Do not fertilize during this time. |
Zoysia
Type: Warm-season
Feeding Frequency: Moderate
Fertilizer Type: Slow-release nitrogen, or balanced with micronutrients
Zoysia grows densely, which helps crowd out weeds, but too much nitrogen can lead to thick thatch layers. Stick to moderate feeding and aerate every few years.
When & How Much:
| Timing | Nutrient Focus | Application Rate/1,000 sq ft | Notes |
| Late April / Early May | Nitrogen (N), Phosphorus (P), Potassium (K) | 0.5 lb | Wait until 2–3 weeks after full green-up. Include iron if the lawn appears yellow. |
| Late June to Early July | Nitrogen (N) | 0.5 – 1 lb | Keeps your lawn thick and lush through the early summer. Don’t overdo it if it’s dry. |
| August (by 15th) | Nitrogen (N) | 0.5 lb | This is your last feeding before fall. It helps the grass store energy for the off-season. |
| September to November | Potassium (K) | 1.0 lb | Strengthens roots and enhances cold tolerance. Avoid any nitrogen at this point. |
| December to February | None | None | Do not fertilize. |
Centipede
Type: Warm-season
Feeding Frequency: Very Light
Fertilizer Type: Low-nitrogen, low-phosphorus; slow-release or organic blends work best
Centipedegrass is naturally low-maintenance and rarely needs fertilizer. Overfeeding leads to iron chlorosis, thatch buildup, weak growth, and long-term decline. If you’re not sure whether to fertilize or not, don’t.
When & How Much:
| Timing | Nutrient Focus | Application Rate/1,000 sq ft | Notes |
| mid-May | Nitrogen (N) | 1.0 lb | Don’t fertilize too early. Centipedegrass takes its time waking up. Mid-May is your go-ahead. |
| August | Nitrogen (N), Potassium (K) | 1.0 lb with high K content | Optional second feeding. Use if more growth or color is needed. |
| September to November | Potassium (K) | 1.0 lb | Focus on root health now. This helps the grass survive winter in better shape. |
| December to February | None | None | Skip all fertilizers. Only apply lime or sulfur if soil test results recommend it. |
St. Augustine
Type: Warm-season
Feeding Frequency: Moderate
Fertilizer Type: Balanced with higher potassium and phosphorus; slow-release preferred
St. Augustine responds best to fertilizers with a slightly elevated P and K ratio. It also does better with more frequent, moderate feedings rather than big applications.
When & How Much:
| Timing | Nutrient Focus | Application Rate/1,000 sq ft | Notes |
| March to May | Nitrogen (N), Phosphorus (P), Potassium (K) | 0.5 lb | Apply in May or wait until green-up is complete. If your lawn looks yellow, a little iron can boost color fast. |
| June | Nitrogen (N), Phosphorus (P), Potassium (K) | 0.5 lb | Helps keep the grass thick and vibrant through summer. |
| July | Nitrogen (N), Phosphorus (P), Potassium (K) | 1.0 lb | Peak growing month. This feeding supports thick coverage and rich color. |
| August | Nitrogen (N), Phosphorus (P), Potassium (K) | 0.5 lb | One last light dose before things begin to slow down in fall. |
| September | Nitrogen (N) | Max 0.5 lb | Keep it light. Fertilizing after mid-month can do more harm than good as the grass winds down. |
| December to February | None | None | No feeding and no lime either unless your soil test says your pH is off. |
Tall Fescue
Type: Cool-season
Feeding Frequency: Heavy in fall, light in spring
Fertilizer Type: Balanced or high-nitrogen, slow-release
Tall Fescue burns out fast in the heat if you overfeed in summer. Keep fertilizing limited to spring and fall, and overseed annually to maintain density.
When & How Much:
| Timing | Nutrient Focus | Application Rate/1,000 sq ft | Notes |
| February | Nitrogen (N) | 1.0 lb | Early spring application to encourage green-up |
| March to May | Nitrogen (N) | 0.2 – 0.5 lb | Use light doses to help with color and recovery. Too much early N leads to weak roots later. |
| June to August | Nitrogen (N) | 0.2 – 0.5 lb | Avoid feeding unless your lawn looks weak and you’re watering regularly. If you do, use a a slow-release formula |
| September | Nitrogen (N), Phosphorus (P), Potassium (K) | 1.0 lb | Prime feeding time. Focus here and your lawn will reward you. Use a balanced mix like 16-4-8. |
| November | Nitrogen (N), Phosphorus (P), Potassium (K) | 1.0 lb | Final Fall application. Helps build reserves before winter. Strong roots now = better lawn next spring. |
Kentucky Bluegrass
Type: Cool-season
Feeding Frequency: Moderate to heavy (more than Fescue)
Fertilizer Type: Balanced or high-nitrogen, slow-release
Kentucky Bluegrass can handle more nitrogen than Tall Fescue, but it struggles under drought pressure. Make sure your watering is consistent, especially during heat spells.
When & How Much:
| Timing | Nutrient Focus | Application Rate/1,000 sq ft | Notes |
| February | Nitrogen (N) | 1.0 lb | Wake-up call after winter. This is when you want to give it a little push. |
| March to May | Nitrogen (N) | 0.2 – 0.5 lb | Use small amounts to green things up and help with post-winter recovery. Don’t overdo it. |
| June to August | Nitrogen (N) | 0.2 – 0.5 lb | Optional feeding if your grass is struggling. Avoid if it’s hot or dry. |
| September | Nitrogen (N), Phosphorus (P), Potassium (K) | 1.0 lb | Fall is when bluegrass thrives. This feeding sets it up for a strong season. |
| November | Nitrogen (N), Phosphorus (P), Potassium (K) | 1.0 lb | Builds roots before the cold hits. Gives you a head start for spring color. |
A Few Final Fertilization Tips for Any Grass Type
- Always water after fertilizing, or time your application before rainfall so the nutrients move into the soil instead of sitting on top.
- Use a slow-release fertilizer whenever possible. It reduces the risk of burning and gives you more consistent results.
- Always match your fertilizer to your grass type. What benefits warm-season grasses can harm cool-season varieties, and vice versa.
- Get your soil tested once a year so you can match your fertilizer to your lawn’s exact nutrient and pH needs.
Fertilizing is one of the most powerful tools in your lawn care toolbox, but only if you’re using it at the right time and in the right way. A smart fertilization plan will improve your lawn’s color, density, and root health.
Weed, Pest & Disease Management
Raleigh’s climate is perfect for lawn growth, but unfortunately, it’s also perfect for broadleaf weeds, grubs, fungus, and a few insects that seem to want to come around every year. They tend to show up fast, spread quickly, and hang around longer than you’d like.
But a healthy lawn is your first line of defense.
When your grass is strong, thick, and well-maintained, it naturally crowds out weeds and becomes less inviting to pests and disease.
Let’s break it down by threat so you know what to watch for and what you should do when things start to go sideways.
Weeds
The key to weed control is timing. If you wait until they’re everywhere, then you’ll spend most of your time just playing catch-up. For most Raleigh lawns, that means putting down pre-emergents or post-emergents, depending on what you have:
Pre-emergents
Put down pre-emergent herbicide for crabgrass and other summer weeds between mid-February and mid-March. You’re looking for a stretch where the soil holds steady at 55°F for three days. That’s when weed seeds start to germinate, and that’s your opportunity to stop them before they break the surface.
Post-emergents
For broadleaf weeds like dandelion, clover, and chickweed, or other weeds, use a post-emergent herbicide around October-November when these weeds are smaller.
Cooler temps and moist soil make these weeds more vulnerable and easier to knock them out. And unless you’re dealing with a major infestation, you don’t need to blanket your entire lawn. Spot-spraying usually does the job just fine.
Organic Solutions
Corn gluten meal can act as a natural pre-emergent, although it’s less consistent, and it could potentially stop grass from seeding.
For visible weeds in small areas, spot-treating with boiling water or a homemade mix of white vinegar (1 gallon), salt (1 cup), and dish soap (1 tablespoon) can kill what’s above the surface, but it won’t stop weeds from coming back. These methods don’t reach the roots, so regrowth is still likely.
If weeds keep coming back, check your mowing height and soil health. Weeds love thin, stressed lawns. Keep mowing and fertilizing routines tight, and most weeds won’t get a chance to move in.
Pests
If your lawn looks patchy for no apparent reason, it might not be just the heat getting to it. It very well could be something chewing through the roots. Pests usually show up without warning, and by the time you notice something’s off, they’ve already done some damage. Here are the ones to watch out for in Wake County:
Grubs
Grubs are white beetle larvae that feed on grass roots, usually starting in June. They leave behind soft, spongy patches that peel back like loose sod.
Ways to treat Grubs:
- Preventative: Apply products like chlorantraniliprole (e.g., GrubEx) late April–early May to stop eggs from hatching.
- Curative: Use trichlorfon (Dylox) July–August if you find 5–10 grubs per square foot. Water thoroughly after application.
- Organic: Introduce beneficial nematodes to infected areas in moist soil.
Chinch Bugs
Chinch bugs are tiny but brutal, especially in Bermuda, St. Augustine, and Zoysia lawns. They suck the moisture out of grass blades and leave behind dry, brittle patches that look just like drought damage.
You’ll usually spot the signs in mid-summer, especially in hot, dry areas of the lawn. Look for yellowing grass with reddish tips and use the flotation test:
- Cut the bottom off a coffee can, press it into the soil near damaged grass, and fill with soapy water.
- Wait 5 to 10 minutes and if Chinch bugs are active, they will have floated to the surface.
Ways to treat Chinch Bugs:
- Chemical: Spray bifenthrin if you find 25–30 bugs per square foot.
- Organic: Apply neem oil to nymphs in early stages or plant endophyte-enhanced grass varieties.
Armyworms
Armyworms usually show up in North Carolina in August, but they can start doing damage as early as July. And when they do, they move quick.
One day your lawn looks fine. The next, it’s chewed down and brown. If you see signs of sudden, expanding damage, a fast-acting insecticide is usually the best solution.
Ways to treat Armyworms:
- Chemical: Use fast-acting spinosad or beta-cyfluthrin at the first sign of damage.
- Organic: Apply Bacillus thuringiensis (Bt) every 5–7 days during outbreaks.
- Monitor: Set pheromone traps in July to catch adults early.
Fire Ants
Fire ants are a regular problem in sunny, open lawns around Raleigh.
Ways to treat Fire Ants:
- Start with a broadcast bait to target the colony below ground: Apply spinosad-based bait in August–October.
- Mound treatment for any remaining activity: Use acephate dust or pour 2 to 3 gallons of boiling water directly into any remaining mounds.
- Organic: You can try applying diatomaceous earth around mounds to dehydrate ants.
Try to always confirm the pest before applying any treatments, then choose the best or easiest method that fits your yard. If you’re not sure what you’re dealing with, you might need to dig a little. Look under the thatch layer or in the soil near problem areas. If you’re not getting clear answers, try calling a Raleigh pest control company.
Lawn Diseases
Most lawn diseases in this area are fungal, and they love one thing: moisture. Combine high humidity with warm nights and overwatered lawns, and it’s the perfect environment for turf diseases to spread. Here are the lawn diseases you’re most likely to see in Wake County:
Brown patch
Brown patch can affect all common lawn grasses, but it mostly affects Tall Fescue and Perennial Ryegrass. You’ll usually see it start to develop when the humidity is high and the nights stay warm (above 65°F), in late spring and early summer.
Kentucky Bluegrass can also get it, but the symptoms are less severe.
It starts as circular or irregular patches of brown, sunken grass with a smoky outer ring. Overwatering, high nitrogen, and mowing too low can all make it worse.
You can help prevent it by improving airflow, watering early in the day, and rotating fungicides like azoxystrobin or propiconazole if it spreads.
Large patch
This disease targets most of your warm season grasses like, Bermuda, Zoysia Centipede, and St. Augustine lawns. It’s basically a more aggressive version of brown patch, caused by the same fungus (Rhizoctonia solani), but it creates much larger, more defined circular patches.
It tends to show up in spring and fall when conditions are cool and damp, right as your warm-season grass is either coming out of dormancy or heading into it.
You’ll usually see small spots at first, but they expand into large, brown circles with orange or yellow edges. Centipede and St. Augustine lawns are hit hardest since they recover more slowly than other types
Avoid overwatering and high nitrogen applications during early spring and fall, and try to keep thatch under control to minimize the risk.
Dollar Spot
Dollar spot usually shows up in Kentucky Bluegrass and Perennial Ryegrass, especially when your lawn’s running low on nitrogen. But cool-season grasses, like Bermuda and Zoysia can get hit too.
You’ll usually notice the early signs on the blades themselves, with straw-colored lesions and narrow, reddish-brown borders that sometimes form into an hourglass pattern across the blades.
If you’re out early in the morning, you’ll be able to see fine white fungal webbing stretched across dew-covered grass.
If left untreated, the lesions will wrap around and choke off each grass blade, creating dead patches that sink and spread out. Over time, you’ll end up with thinning turf and blotchy spots that make your lawn look weak and worn out.
Gray Leaf Spot
Gray leaf spot is a fungal disease that poses a significant threat to certain turfgrasses, particularly Perennial Ryegrass, Tall Fescue, and St. Augustine grass. It thrives in warm, humid conditions, especially when temperatures sit between 70°F and 95°F and leaf surfaces remain wet for more than 14 hours.
Young lawns (less than a year old) are most at risk, particularly 4–5 weeks after seeding or sodding. But it can also take hold on more established lawns if you go heavy on nitrogen. Over-fertilizing encourages soft, lush growth, which is exactly what this fungus loves.
Early symptoms include small brown or tan spots with purple margins, which develop into gray, fuzzy lesions (from fungal spores) in high humidity. These lesions girdle and kill blades, starving the grass.
Once it starts, it can spread rapidly through wind, rain, mowers, and pets, leaving large bare patches that appear to have been scorched overnight.
If you begin to notice it on your lawn, try to manage it by keeping the area it’s in dry. Follow up by reseeding the area the following year, and consider calling a professional to apply preventative fungicides.
You don’t have to treat every inch of your yard every season, but you do need to stay observant. Don’t wait until half your lawn is damaged. When you catch these problems early, they’re manageable. But if you wait too long, you’ll be in full-blown damage control.
If you’re seeing unusual spots, discoloration, or patches that are starting to spread through your lawn, the NC State TurfFiles site is a great local resource with photos to help you identify what exactly is causing problems and treatment recommendations.
Core Aeration & Dethatching
At some point, even a well-cared-for lawn starts to feel like it’s hitting a wall. Growth slows down, water doesn’t soak in as easily, and no matter how much you fertilize or water, it just doesn’t bounce back the way it used to. That’s usually a sign your lawn needs to breathe.
This is where aeration and dethatching can help.
Core Aeration
Over time, soil naturally compacts. This mostly happens in high-traffic areas or in clay-heavy yards like we have in the Triangle. Whit overly-compacted soil, roots can’t expand, nutrients get trapped at the surface, and oxygen has a hard time reaching where it’s needed most.
Core aeration solves that by punching small holes into the lawn and removing plugs of soil. This opens up space for air, water, and nutrients to move deeper into the root zone.
Think of it like hitting reset on your lawn’s ability to absorb everything you’re putting into it. The plugs are pulled out and sit on top of the ground and will naturally decompose within weeks.
Here’s when to do it:
- Bermuda, Zoysia, Centipede, and St. Augustine: Late May through June, once the lawn is actively growing and can recover quickly.
- Tall Fescue, Ryegrass, and Bluegrass: Best done in September, when soil temps are still warm, and the grass is pushing strong root growth.
If you’re overseeding, especially with cool-season grasses, aerate right before. It improves seed-to-soil contact and gives new roots room to grow.
Dethatching
If your lawn feels unusually spongy or soft when you walk across it, there’s a good chance you’re dealing with thatch.
What Is Thatch?
Thatch is a layer of living and dead grass stems and roots that builds up just above the soil. While surface debris like grass clippings and fallen leaves decompose quickly and can actually help feed your lawn, thatch forms deeper down and doesn’t break down as easily.
Some thatch is normal. But once it gets thicker than ½ inch, it starts working against your lawn by:
- Holding too much moisture near the surface
- Blocking water, air, and nutrients from reaching the soil.
- Creating the perfect conditions for pests and fungal diseases.
What Causes Thatch Buildup?
Warm-season grasses like Bermuda and Zoysia are most likely to develop thatch, since they spread aggressively and layer up over time. But other factors can make it worse, including:
- Overwatering
- Over-fertilizing (especially with nitrogen-heavy blends)
- Frequent pesticide use
All of these can slow down the natural breakdown of organic material in the lawn.
How to Check for Thatch
If you’re not sure whether your lawn has a thatch problem, use a garden trowel or shovel to remove a small, 3-inch-deep section of grass. Look for a straw-like layer between the grass blades and the soil. If this layer is thicker than half an inch, it’s time to dethatch.
When to Dethatch
Warm-season grasses (Bermuda, Zoysia, St. Augustine):
Late spring to early summer, when the lawn is actively growing and can bounce back quickly.
Cool-season grasses (Tall Fescue, Ryegrass, Kentucky Bluegrass):
Dethatching is rarely necessary, unless the lawn has been neglected or overfertilized. If needed, early fall is the best time, when temperatures are cooler but the grass is still growing strong.
How to Dethatch Your Lawn
Before you start:
- Mow your lawn slightly shorter than usual
- Water lightly a day or two ahead of time—this softens the soil and makes dethatching less stressful on the grass
Manual Dethatching
Best for small lawns or light buildup. Use a dethatching rake with sharp, curved tines to slice into the thatch layer. A regular leaf rake won’t cut it.
Power Dethatching (Vertical Mowing)
For heavier thatch, rent a vertical mower or hire a professional service that offers power raking. Make sure the blades are set to skim just below the grass surface. Going any lower could potentially damage the soil or roots.
After dethatching:
- Overseed any bare areas to help the lawn recover and fill in thick.
- Apply a balanced fertilizer to support recovery.
- Consider core aeration to improve soil health and reduce future compaction.
Aeration and dethatching aren’t tasks that need to be done every season. But when your lawn starts feeling sluggish or just isn’t responding like it used to, they’re usually the best way to get things back on track, without having to start all over.
Seasonal Task Checklist for a Healthy Lawn Year-Round
Even if you don’t get everything perfect, staying in sync with the seasons can make a big difference in how your lawn looks and feels.
Raleigh’s weather doesn’t always stick to a predictable schedule, but the general flow of the seasons stays consistent enough to guide your maintenance plan.
Here’s a breakdown of what to focus on throughout the year:
Spring (March – May)
Spring sets the stage for the entire growing season. If you nail the preparation (especially soil health and weed prevention) and you’ll save yourself a lot of trouble once the summer heat rolls in.
What to do:
- Soil test every 2–3 years (NC State’s free soil test kits available at local extension offices).
- Apply lime or sulfur if soil pH is outside the ideal 6.0–6.5 range (critical for nutrient uptake).
- Apply pre-emergent herbicide for crabgrass by mid-March, when soil temperatures reach 55°F. Consider a split application with a second round around May 1 for better control.
- Fertilize warm-season grasses (Bermuda, Zoysia) after green-up (late March–April).
- Spot-spray broadleaf weeds (dandelions, clover) in April–May if temperatures exceed 60°F.
- Get your mower ready: sharpen blades, change oil, and check equipment.
- Lightly fertilize Tall Fescue only if soil test shows a deficiency (avoid overfeeding; save nitrogen for fall).
- Aerate Bermuda and Zoysia lawns in late May when actively growing.
Summer (June – August)
Summer is all about stress management. Your job is to keep the lawn alive, not lush. Prioritize survival watering, proper mowing, and watching for pests.
What to do:
- Water deeply but not too often. Aim for about 1 inch per week, split into 1–2 watering sessions, preferably early morning to minimize evaporation. Never in the evening.
- Watch for signs of grubs, chinch bugs, and armyworms.
- Adjust mowing height to reduce heat stress.
- Lightly fertilize warm-season lawns with a slow-release fertilizer if needed.
- Keep mower blades sharp and mow consistently.
- Avoid fertilizing Tall Fescue. Focus on deep watering and shade management instead.
- Use iron supplements if warm-season grass starts yellowing.
Fall (September – November)
This is the recovery season. For cool-season grasses, fall is your biggest opportunity to build density and root strength. Warm-season lawns are prepping for dormancy.
What to do:
- Aerate cool-season grasses before or during seeding.
- Overseed cool-season grasses like Tall Fescue between mid-September and mid-October at 6–8 lbs seed per 1,000 sq. ft., using starter fertilizer.
- Apply 1 lb nitrogen per 1,000 sq. ft. to cool-season grasses.
- Fertilize warm-season lawns with potassium to boost winter hardiness.
- Dethatch Zoysia and Bermuda if thatch exceeds ½ inch.
- Keep removing fallen leaves to avoid matting and mold.
- Spot-treat broadleaf weeds with post-emergent herbicides in October–November when temperatures are between 50–75°F, targeting chickweed, clover, and other winter annual weeds.
Winter (December – February)
Winter is the reset. Grass growth slows or stops completely, but behind the scenes, your lawn is storing energy and getting ready for spring. This is the time to stay off it, make plans, and handle all the prep that doesn’t require green grass.
What to do:
- Limit foot traffic when the ground is frozen to avoid damaging dormant grass crowns.
- Clean and store lawn equipment.
- Sharpen mower blades and prep for spring.
- Mark February 15 on your calendar for crabgrass pre-emergent application.
- Spread compost on bare areas to improve soil structure for spring growth.
- Start planning any renovations or turf replacements.
- Monitor your lawn for drainage issues after heavy winter rains and fill low spots where water collects using a sand/compost mix.
- Apply lime during winter if your soil pH is below 6.0.
Stick to the rhythm of seasons, and you’ll spend less time reacting and more time enjoying your yard. It doesn’t need to be perfect. Just try to stay consistent.
Sustainable & Regulatory Tips
A healthy lawn doesn’t have to come at the expense of your water bill or the environment. You don’t need to load it up with chemicals or waste water to get results.
In fact, the more intentional you are with how you care for your lawn, the better it will perform and the fewer problems you’ll run into with things like runoff or soil degradation.
Here are a few smart habits that work well in Raleigh’s climate and that can help keep your lawn (and our environment) in good shape:
1. Follow Raleigh’s Watering Guidelines
Raleigh uses an odd/even watering system during drought stages. That means:
- If your address ends in an odd number, water on Tuesday, Thursday, and Saturday.
- If it ends in an even number, water on Wednesday, Friday, and Sunday.
Always check current rules through the City of Raleigh or Wake County. These can change depending on the amount of rainfall and reservoir levels.
2. Apply Lawn Care Products Responsibly
Always read the label. Actually read it. Whether it’s herbicide, pesticide, or fertilizer, applying more than the recommended amount doesn’t give you better results. It just increases the risk of runoff, turf burn, or damage to nearby plants and trees.
3. Use Slow-Release or Organic Fertilizers
Quick-release fertilizers might green up your lawn faster, but they also wash out quicker. Especially when we get one of those downpours that come with summer storms.
A lot of fertilizer ends up in our local waterways because of runoff, which can lead to algae blooms and water quality issues.
Try to use slow-release or organic fertilizers whenever possible. They feed your lawn gradually, stay put instead of washing away, and lower the risk of burning your grass.
Plus, they don’t need to be applied as often, which makes your feeding schedule more forgiving if you’re busy.
4. Grass-Cycle Your Clippings
Instead of bagging your clippings, leave them on the lawn. Just make sure they’re not clumping up. This is one of the easiest ways to naturally return nutrients to the soil. It saves you time, reduces landfill waste, and helps improve moisture retention in your soil.
5. Capture Rainwater
If you’re looking to cut back on your water bill or make your yard more self-sufficient, installing a rain barrel or cistern is a simple, effective place to start.
Collected rainwater is perfect for hand-watering garden beds, spot-treating dry patches, or rinsing tools without having to tap into your main water source.
The City of Raleigh’s Rainwater Rewards program makes this even more appealing. Depending on where you live, you could qualify for 75% to 100% reimbursement on eligible projects like rain barrels, rain gardens, permeable pavement, and more. The city even offers consultations to help you choose the right project for your property.
Beyond saving money, capturing rainwater helps reduce runoff, limits erosion, and keeps pollutants from entering local waterways.
To get started:
- Check your address on the city’s Rainwater Rewards map to see your reimbursement level (75%, 90%, or 100%)
- Request a consultation through the city’s online form
- Complete the project, submit your receipts, and get reimbursed
It’s a smart way to support your lawn and help protect Raleigh’s water systems without spending a ton out of pocket.
A sustainable yard isn’t just better for the environment. It’s also easier to live with. When you stop forcing your lawn to grow with too much water or too many chemicals, it actually performs better. It holds up longer, looks healthier, and needs less from you in the long run.
