Why Chicago Lawns Need Attention Through the First Frost

While visible growth slows as the air chills, these resilient grass varieties thrive in cooler conditions. Marc Harris, operations manager for Dr. Green Services, warns that abandoning lawn care too early leaves turf vulnerable. The University of Illinois Extension emphasizes that late summer and early fall serve as critical windows for root development and recovery.

Homeowners should continue mowing as long as the grass shows signs of life, though they must avoid removing too much of the blade at once. Beyond cutting, managing leaf litter is essential; while a light layer can be mulched, dense piles block necessary sunlight and can suffocate the grass. Watering needs also shift, requiring less supplemental moisture than during the summer heat, though consistent monitoring remains vital. Properly timed fertilization provides the final boost needed for winter dormancy, setting the stage for a stronger return when spring arrives.
