Annual Lawn Care Schedule for Illinois Homeowners

Quick Answer

A healthy lawn in Illinois requires consistent, seasonal care—from spring prep and weed prevention to fall aeration and winterizing.

Month-by-Month Breakdown

Early Spring (March–April)

• Clean up leaves and debris

• Apply crabgrass preventer

• First round of fertilizer

  
  

Late Spring (May–June)

• Weed control treatments

• Begin consistent weekly mowing

• Monitor watering as temps rise

  
  

Summer (July–August)

• Maintain mowing height (don’t cut too short)

• Spot treat weeds

• Water deeply, 1–1.5” per week

  
  

Fall (September–October)

• Core aeration

• Overseeding

• Fall fertilization (critical for root growth)

  
  

Late Fall (November)

• Final cleanup (leaves, debris)

• Winterizer fertilizer application

  
  

Why This Matters

Skipping or mistiming steps leads to:

• More weeds

• Thinner grass

• More work (and cost) later

  
  

What Homeowners Should Do

• Follow a consistent seasonal plan

• Stay ahead of weeds instead of reacting

• Consider a structured lawn care program
