Anyone used a soil conditioner before? I have some soil issues in a couple spots at our new house. I pretty much turned the place upside down so there is places with top soil on the bottom and bottom soil on the top. The soil I have in the front yard is as hard as concrete in spots. They sell stuff with kelp in it that is supposed to loosen soil and promote drainage and root growth. You just spray the stuff on. Anyone use anything like this?
