Fall is the most important season for your lawn in Central Illinois. Cool nights and warm days help grass put energy into roots instead of just blades. What you do now affects how green and healthy the lawn looks next spring. Here’s how to make the most of it.
Fertilize in early to mid-fall
September through October is the ideal window. The grass is still growing but not under summer heat stress, so it uses the nutrients to build roots and store energy. Use a product suited for fall (often higher in potassium) and follow the label rate. For more on timing and products, see fertilizing 101.
Overseed thin or damaged areas
If you have bare spots, thin turf, or areas damaged by summer, fall is the best time to seed. Soil is still warm, and cool-season grasses establish well. Keep the seed moist (light, frequent watering) until it germinates, then transition to deeper, less frequent watering as it grows. Avoid heavy foot traffic on new seed.
Keep mowing at the right height
Continue mowing at your normal height (about 3–3½ inches) until growth slows. Don’t let the lawn go into winter with grass that’s too long—it can mat down and encourage disease. See mowing height by season for when and how to lower the blade for the last cuts.
Manage leaves
A thin layer of mulched leaves can be fine; a thick mat blocks light and can harm the grass. Mow over light leaf cover to chop them up, or rake and remove if there’s a lot. Don’t let leaves sit on the lawn for weeks.
One last edge and trim
A final clean edge and trim leave the yard looking neat going into winter and make spring cleanup easier. For technique, see edging and trimming basics.
