most people aerate and just leave the cores sitting, no biggie. They holes will eventually close on there own in a short amount of timeM311att said:Well... I went with some milorganite and here is why. I already have a lawn fertilizer company so I didn't want to double up on that. Next, I've had good luck with Milo in the past so I planned on using it and am hoping I can bury the smell with the sand. I put down about 2 tons so far. I have to say that I got my feelings a little hurt just now. After 4 strong hours of brushing sand I watered it in and most of my aeration holes reappeared. WTF mate?
