I was just wondering how late is too late for aeration? I am not overseeding, just have a few people that I plan to aerate and fertilize the lawns. We have been so dry but are starting to see rain in my area. I plan to do some aerating in 2 weeks but if we wouldn't see much rain, I want to wait until the soil is moist enough to penetrate. Is late Oct/Nov too late? Also, some neighbors of mine are looking for a lawn service. I am just starting out doing this on the side and I am doing the aeration for them. What is everyones experience, is it usually a good or bad thing when it goes from a mowing or small job here and there to something bigger?
