Autumn lawn maintenance includes mowing at the right height, aerating, reseeding bare patches, fertilizing before winter, and clearing debris.

We’re going to cover all these aspects. Get ready; it’s time to prepare your lawn for the winter season.

Mow at the Proper Height

In the fall, keep your lawn’s mowing height between 2-3 inches to allow more sunlight and help your grass grow thicker.

Here are some lawn care suggestions for September:

  • Gradually decrease mowing height over several weeks.
  • Avoid cutting it too short – you’re not trying to give your lawn a buzz cut!
  • Leave some leaf blades so your lawn can store energy.
  • Maintain your lawn in the fall by keeping mower blades sharp.
  • A clean cut prevents unnecessary tearing and damage.
  • Consider it more like giving your grass a tidy trim rather than a rushed haircut.

Follow these steps for fall lawn care to keep your lawns healthy!

Aerate the Lawn

To promote the root health of your lawn, it’s best to aerate your lawn during cooler temperatures. September is the ideal time for fall lawn care.

Both tools are highly effective in prepping your lawn for the fall.

After aeration, it is important to topdress the lawn with compost. This process replenishes your yard’s ecosystem and preps it for winter.

Overseed Bare Spots

Fall lawn care services highly recommend overseeding the bare spots in your lawn.

Here are the tips:

Overseeding repairs bare spots caused by traffic, pets, or disease. Remove debris, loosen soil, and fill low areas with topsoil.

Choose cool-season grass varieties suited for the local climate.

Distribute seed per label rate and rake lightly to cover.

Keep seeds moist by watering 3 times daily until 1-inch growth. This restores a lush lawn appearance.

Preparing your lawn in the fall leads to a healthy, lush lawn in the spring!

Fertilize Before Winter

Applying fertilizer to your lawn before winter is essential.

Here are concise tips for fertilizing lawns before winter:

  • Fertilize 6-8 weeks pre-frost for nutrient uptake before dormancy
  • Use balanced and slow-release fertilizers like 10-10-10 to avoid excess growth
  • Replenish potassium for cold tolerance.
  • 0.5-1 lb nitrogen/1,000 sq ft fuels roots, not growth
  • Water in fertilizer and supplement iron for color
  • Don’t fertilize too early or after dormancy.

Fertilize in late September for optimal nutrient absorption by the roots and to avoid late growth in cold weather.

Remove Leaves and Debris

Maintaining your lawn during fall involves keeping it clear of leaves and other debris hindering sunlight and oxygen.

Here are key tasks:

  • Weekly leaf raking or blowing: This isn’t just a seasonal chore; it’s essential for fall yard prep.
  • Leaf disposal or composting: You can choose between composting or disposing of them.

Leave some leaves on your lawn, as they can act as a natural fertilizer when decomposing.

The next step is to learn how to protect your lawn against weeds and pests.

Protect Your Lawn Against Weeds and Pests

Protect your lush lawn from pesky weeds and pests with pre-emergent herbicides.

Apply Pre-Emergent Herbicide

Applying pre-emergent herbicide in September prevents weed growth, including crabgrass dandelions and foxtail, which is important for lawn care.

Apply pre-emergent based on weed types in early spring per instructions, avoiding interference with lawn seeding by timing it when the soil cools.

Aerate and overseed before applying in the fall for good seed-to-soil contact. Timing is key for effective pre-emergent and weed prevention.

Stay tuned as we’ll discuss how to treat grubs and other pests next.

Treat for Grubs and Other Pests

Grubs, chinch bugs, and armyworms often infest lawns in the fall, causing dead patches and dry spots.

Treating early with insecticides like carbaryl and trichlorfon or organic options like beneficial nematodes or milky spore is key to preventing larger infestations later.

Carefully following product instructions when treating this fall ensures a healthy lawn without pest damage.

Adjust the Watering Schedule for Cooler Weather

Fall lawn watering tips.

Water Deeply But Infrequently

As temperatures fall, gradually reduce the frequency and duration of lawn watering. Aim to water deeply but infrequently, applying 1-1.5 inches of water per week based on soil probe checks. Water early in the day to allow time for drying before night.

Proper water reduction hardens grass plants for winter dormancy.

Allow Lawn to Go Dormant

Allowing lawns to go dormant in winter is natural and aids grass survival.

Avoid watering once frost arrives to prevent freezing roots. While appearing dead above ground, dormant lawns remain alive below. Reduced fall and winter watering hardens grass plants, enabling quicker spring green-up when growth resumes.

Create Your Checklist for Fall Lawn Care

Your lawn may seem like a simple patch of green, but it requires more care than expected.

Here are some essential lawn care tips for the fall months of September, October, and November.

September Lawn Care Tips

September is a crucial month for lawn care. It’s time to start overseeding bare patches and aerating compacted soil. Here’s a suggested action plan:

  • Overseed and Aerate:
    • Overseed effectively, ensuring each bare patch is addressed.
    • Aerate your lawn to help it breathe and absorb nutrients better.
  • Weed Control, Fertilization, Pest Treatment:
    • Use pre-emergent weed control to protect your lawn from unwanted plants.
    • Feed your lawn with balanced turf food to promote healthy growth.

October Lawn Care Tips

In October, continue mowing at lower heights while blades remain sharp, treat any leftover weed and pest issues, remove fallen leaves promptly to prevent smothering grass, adjust watering for cooler weather, and prepare equipment for winter storage to ensure a smooth transition into the off-season.

November Lawn Care Tips

It’s November, and your lawn still needs attention. Follow these tips for a healthy lawn.

  • Mow your lawn before winter.
  • Clear all sticks, leaves, and other debris. Think of it as a deep cleaning for your yard.

So, you’ve chosen to employ a professional for your lawn care requirements this fall? That’s a smart move!

We will discuss aeration, overseeding, fertilization, and pest control here.


Aerating in early fall relieves soil compaction, reduces thatch buildup, and enables deeper rooting before winter dormancy.

Use a core aerator and target mid-August to mid-September for cool-season grasses when soils are still warm, but temperatures are cooler.

Combine with overseeding to fill bare spots in the loosened soil.

Proper fall aeration every 1-3 years leads to thicker, greener, and healthier turf grass.


Overseeding can help achieve a lush lawn without the expense and pain of hair transplants.

Slice seeders create precise furrows for seeds, better than random scattering.
