November in the Southeast is that sweet spot where the air turns crisp but your lawn still has life in it. What you do right now—before your warm-season grass goes dormant—makes all the difference between a lawn that rebounds beautifully in spring and one that limps out of winter patchy and thin.

Whether you’re growing Bermuda, Zoysia, Centipede, or St. Augustine, here’s your complete game plan for winterizing your Southeast lawn.

Know Your Grass Type (It Actually Matters)

Southeast lawns are almost exclusively warm-season grasses, and each one has quirks that affect your winter prep:

  • Bermuda grass is the toughest and most cold-tolerant of the bunch. It goes dormant and turns brown but recovers aggressively in spring.
  • Zoysia is slower to green up in spring but handles shade and cold better than Bermuda.
  • St. Augustine is the most cold-sensitive. A hard freeze can cause real damage, especially to varieties like Floratam.
  • Centipede grass needs the least fertilizer of all—over-fertilizing in fall is one of the most common mistakes homeowners make with this grass.

Understanding which grass you have prevents costly mistakes. For instance, applying a heavy nitrogen fertilizer to Centipede in November can actually weaken it heading into winter.

Gradually Lower Your Mowing Height

Don’t just scalp your lawn in one pass. Over the course of October and November, gradually reduce your mowing height across 3-4 sessions:

  • Bermuda: Final height of 1–1.5 inches
  • Zoysia: Final height of 1.5–2 inches
  • St. Augustine: Final height of 2.5–3 inches (never scalp St. Augustine)
  • Centipede: Final height of 1.5–2 inches

Cutting too short in one session stresses the grass. Cutting gradually lets the plant adjust and reduces the risk of fungal disease. Shorter grass heading into winter also discourages snow mold and matting—though heavy snow is rare in most of the Southeast, wet, heavy dew and frost sitting on tall blades can cause problems.

Apply a Winterizer Fertilizer (But Do It Right)

Your fall fertilizer application is arguably the most important one of the year. Here’s what to know:

Choose potassium over nitrogen. A fertilizer with a ratio like 0-0-25 or 5-0-20 is ideal. Potassium strengthens cell walls, improves cold tolerance, and helps roots store energy for winter. High-nitrogen fertilizers push tender new leaf growth that’s vulnerable to frost—exactly what you don’t want in November.

Timing matters. Apply your winterizer 4-6 weeks before your area’s average first hard frost. For most of the Southeast, that means late October through mid-November.

Don’t fertilize Centipede the same way. Centipede grass needs very little fertilizer. If you’ve already fertilized this fall, skip the winterizer entirely. Over-fertilizing Centipede leads to “Centipede decline”—a gradual weakening that’s hard to reverse.

Aerate If Your Soil Needs It

Fall aeration is a powerhouse move for Southeast lawns, but timing is key. You want to aerate while your grass still has a few weeks of active growth left—typically early to mid-November in the Southeast.

Signs your lawn needs aeration:

  • Water puddles or runs off instead of soaking in
  • Soil feels rock-hard when you push a screwdriver into it
  • Your lawn gets heavy foot traffic (kids, pets, parties)
  • Thatch layer is thicker than half an inch

Use a core aerator—not a spike aerator. Core aerators pull actual plugs of soil out, creating channels for air, water, and nutrients. Spike aerators just compress the soil further. You can rent a core aerator from most hardware stores for about $75-100 per day.

Leave the soil plugs on the lawn. They’ll break down in a week or two and help distribute beneficial microbes back into the soil.

Overseed with Ryegrass for Winter Color (Optional)

One of the Southeast’s unique advantages: you can overseed your dormant warm-season lawn with annual ryegrass for green color all winter long.

How to overseed:

  1. Mow your existing lawn shorter than usual (about 1 inch for Bermuda)
  2. Spread annual or perennial ryegrass seed at 8-10 pounds per 1,000 square feet
  3. Lightly rake or topdress with a thin layer of compost
  4. Water daily for 7-10 days until germination, then taper to every 2-3 days

One caveat: Overseeding can slow your warm-season grass’s spring green-up because the ryegrass competes for resources. If a fast spring recovery is your priority, skip the overseeding.

Stay on Top of Leaf Removal

Fallen leaves are one of the biggest threats to your lawn heading into winter. A thick layer of leaves blocks sunlight, traps moisture, and creates the perfect breeding ground for fungal diseases like brown patch and large patch.

Your options:

  • Mulch mow light leaf coverage. Run your mower over them to chop leaves into small pieces that decompose quickly and feed the soil.
  • Rake or blow heavy leaf coverage. If you can’t see the grass through the leaves, they need to come off.
  • Compost collected leaves. They make excellent garden mulch by spring.

Aim to clear leaves at least once a week through November and December. It’s tedious, but it’s one of the simplest things you can do for your lawn’s health.

Dial Back Watering—But Don’t Stop Completely

As temperatures drop, your lawn’s water needs decrease dramatically. But “less water” doesn’t mean “no water.”

Guidelines for winter watering in the Southeast:

  • Water only if there’s been no rain for 2-3 weeks
  • When you do water, apply about half an inch—enough to moisten the root zone
  • Water in the morning so the grass dries before nightfall (wet grass overnight invites disease)
  • If you overseeded with ryegrass, you’ll need to water more frequently until it establishes

If you have an irrigation system, adjust your controller for winter. Many homeowners forget this step and end up overwatering, which leads to fungal problems and wasted water.

Apply Pre-Emergent Herbicide for Winter Weeds

Winter annual weeds like henbit, chickweed, and annual bluegrass germinate in fall when soil temperatures drop below 70°F. A pre-emergent herbicide applied in early to mid-November creates a barrier that stops these weed seeds from sprouting.

Important notes:

  • If you’re overseeding with ryegrass, do NOT apply pre-emergent—it will kill your ryegrass seed too.
  • Spot-treat any existing weeds with a post-emergent herbicide labeled for your grass type.
  • Read labels carefully. Some products are not safe for Centipede or St. Augustine.

Test Your Soil

If you haven’t tested your soil in the last 2-3 years, November is a great time to do it. Your local cooperative extension office offers soil tests for $10-15 in most Southeast states.

A soil test tells you:

  • pH level — Southeast soils tend to be acidic. Most warm-season grasses prefer a pH of 6.0-6.5. If your soil is too acidic, a lime application in fall can correct it over the winter months.
  • Nutrient levels — You might discover you’re deficient in phosphorus, potassium, or micronutrients like iron.
  • Organic matter content — Low organic matter means your soil doesn’t hold water or nutrients well.

Don’t guess. A $15 soil test can save you hundreds in misapplied fertilizers and amendments.

Protect Cold-Sensitive Grass

If you’re growing St. Augustine or certain Centipede varieties in the upper Southeast (North Carolina, Tennessee, northern Georgia), take extra precautions when hard freezes are forecast:

  • Avoid mowing within 48 hours of a predicted freeze
  • Water the lawn the day before a freeze—moist soil holds heat better than dry soil
  • Don’t walk on frosted grass. Frozen grass blades snap and won’t recover until spring.

Your November Checklist

Here’s a quick-reference checklist to keep you on track:

  • ✅ Identify your grass type and adjust care accordingly
  • ✅ Gradually lower mowing height over 3-4 sessions
  • ✅ Apply a potassium-rich winterizer fertilizer
  • ✅ Core aerate compacted areas
  • ✅ Overseed with ryegrass (optional, for winter color)
  • ✅ Remove fallen leaves weekly
  • ✅ Reduce irrigation frequency
  • ✅ Apply pre-emergent herbicide (unless overseeding)
  • ✅ Test soil and amend as needed
  • ✅ Protect cold-sensitive grasses from hard freezes

Taking these steps now pays dividends when spring rolls around. You’ll spend less time fixing problems and more time enjoying a lawn that’s already ahead of the game.
