Spring Lawn Care Checklist for Illinois Homeowners

Spring is the most important season for your lawn. What you do in the first few weeks sets the tone for the entire year. Here's what Illinois homeowners should focus on.

Clean Up Winter Debris

Remove fallen branches, leaves, and any debris that accumulated over winter. This prevents mold and allows sunlight to reach the grass. Rake lightly to break up matted areas without damaging new growth.

Test Your Soil

Soil pH affects how well your lawn absorbs nutrients. Illinois soil tends to run slightly acidic. A simple test tells you if you need lime or sulfur amendments before fertilizing.

Aerate Compacted Areas

Heavy foot traffic and winter freeze-thaw cycles compact soil. Core aeration opens up the ground so water, air, and nutrients reach the roots. Timing matters — too early and you stress the grass.

Apply Pre-Emergent Weed Control

Pre-emergent herbicide stops crabgrass and other weeds before they sprout. The window is narrow — apply too late and it won't work. Soil temperature is the key indicator, not the calendar date.

Set Your Mowing Height

Most cool-season grasses in Illinois do best at 3 to 3.5 inches. Cutting too short stresses the grass and invites weeds. Sharp blades make clean cuts that heal faster.
