The optimal period for lawn aeration depends significantly on the type of grass present. Cool-season grasses, such as Kentucky bluegrass and fescue, benefit most from aeration during their active growing seasons, typically in the early spring or fall. Warm-season grasses, like Bermuda and zoysia, should be aerated in late spring or early summer when they are actively growing.
Aeration improves soil drainage, reduces compaction, and promotes deeper root growth. This leads to a healthier, more resilient lawn. Historically, aeration was primarily performed on golf courses and athletic fields; however, its benefits are now widely recognized for residential lawns as well, contributing to improved turf quality and reduced susceptibility to disease.
