My lawn was laid in 1999. It's heavy clay. Every fall we aerate it. This year it seems very lumpy (like maybe the cores did not break down or there is small lumps from insects or worms). Is there something I can put down to soften the soil or perhaps thatching would help break up the lumps? Top soil is not realistic as I have 2/3 acre!
Any advice would ne greatly appreciated!
