Sorry to be talking about aeration so much lately but I just got back from walking my dog and we had to come back thru my back yard. I aerated it yesterday . 2 passes. Didn't get the seed down yet. Every fall/spring I wonder to myself why we tell people how great it is to overseed with aeration since the holes are there for the seed. Well I just took a long look at my turf. WHAT HOLES?? WHERE? 80% of them are covered with soil cores. No question how important aeration is....I just wondered if any of you ever had this same thought? Need to be prepared when some customer asks me the same ? and I go ummmm ahh..gee... Saying that the seed will go down when the cores decompose doesn't quite cut it in my book.
