A great lawn is built on timing. In Central Illinois, our climate drives when to mow, water, fertilize, and prep—so having a simple seasonal calendar keeps you ahead instead of playing catch-up. Here’s a year-round overview you can follow.
Spring (March–May)
- March–April: As soil warms and grass greens up, do a spring cleanup—rake leaves and debris, and fix any winter damage. This is a good time for a first pass with the mower if the grass is long enough to cut (see spring lawn prep for details).
- Mowing: Start when grass is actively growing. Set height around 3–3½ inches and mow regularly so you never remove more than one-third of the blade. See how to mow like a pro.
- Fertilizing: If you fertilize, wait until the lawn is actively growing (usually late April–May in our area). Avoid heavy nitrogen too early—it can push top growth before roots are ready.
- Edging and trimming: Re-establish edges along driveways and walkways early so they’re easy to maintain all season. Edging and trimming basics.
Summer (June–August)
- Mowing: Keep a consistent height (3–3½ inches). Mow in the cooler part of the day when the grass is dry. In hot, dry spells, avoid cutting too short—taller grass shades the soil and holds moisture better.
- Watering: Water deeply and less often (early morning is best). For guidance, see watering your lawn.
- Stress: Heat and drought can cause browning. Minimize foot traffic on stressed grass and avoid fertilizing during the hottest weeks unless you’re irrigating. Drought-tolerant lawn care has more tips.
Fall (September–November)
- September–October: Fall is ideal for fertilizing and overseeding if you have thin or damaged areas. Cool nights and warm days help roots grow. See fall lawn care.
- Mowing: Continue mowing at your normal height until growth slows. Lower the blade gradually for the last few cuts so the lawn isn’t left too long going into winter (reduces matting and disease).
- Leaves: Don’t let a thick layer of leaves sit on the lawn—they block light and can encourage disease. Mulch them with the mower or rake and remove.
Winter (December–February)
- Rest: Grass is dormant. No mowing or fertilizing needed. Avoid heavy traffic on frozen or soggy turf to prevent damage.
- Planning: Use this time to schedule spring service or plan DIY tasks. Sharpening mower blades and checking equipment now means you’re ready when growth starts again.
