Fall is the time to renovate our cool-season lawns following are recommendations (aka lawn chores) for this late-summer to early fall growing season.
First analyze your soil. If your soil has become compacted or is very heavy clay, it is best to aerate prior to seeding. Hollow tine aerators work the best. Soil must be slightly moist for successful aeration. If soils are dry the aerator tines will simply bounce off the soil surface, not reaching the correct depth. I always core aerate a few days after it rains.
