The Ohio Lawn Care Calendar: What to Do Month by Month

In Southwest Ohio, the lawn care year runs from an early-spring pre-emergent and feeding, through summer mowing and grub control, to the most important step of all — fall fertilizing, aerating, and overseeding that build a thick lawn for next year.

Why fall is the most important season

Ohio's cool-season grasses do most of their root growth in fall. Aerating relieves our heavy clay soil, overseeding thickens thin spots, and a late feeding stores energy for a fast, green spring.
