Was just wondering if any of you have tried this? The past 2 seasons we have had weeks without rain, on my lawn when this "great" clay soil dries out, it gets rock hard. When it is watered the water just washes off, heading down the street. I do limit the time the sprinklers run at each spot to about 15 min, then water another spot 15 min, then eventually each spot is watered about 1.5 hours total each week. For the past 2 years during this dry time, I pulled out the aerator and aerated my lawn, so far twice this summer. The theory being, with 2-3" deep holes in the ground, water now has an entry point into the soil which will alleviate run off and promote absorption. Guess what, it works VERY WELL! So well in fact, that I'm considering advertising and really promoting this service next year during the summer when things start to dry out. Ideas, comments, or suggestions?
