This may be off base, but I was wondering why folks in the upper Midwest & southern Midwest were aerating in August? Even September, cuz I just checked the NWS map regarding precip since June, and it ain't pretty. I can understand aerating lawns that are irrigated, but how 'bout the bulk of lawns which are not irrigated? We finally received 7/10 of an inch this week. That was the heaviest rain event since mid June. Hoping for more rain so we can "do the job right". imo 1) Are some folks aerating just cuz it fits "their schedule"? 2) Is it best to aerate when soils are moist? 3) What length of aeration plugs are acceptable for you? 4) Do you aerate lawns when air temps exceed 90 degrees?
