I have heavy clay in backyard. I applied this about 3 weeks ago and grass is beginning to sprout in areas. So far so good.
Not sure yet if it's making a difference. Needs more time.
Best investment ever. I had nearly solid clay in my garden, resulting in sub-optimal performance for my flowers. Now after three treatments plus mulch, I have 6-8 inches of rich, fluffy soil. Many friends, seeing my beautiful garden, have sent away for Sound Soil Restore Clay.
Product used on heavy clay garden and made a real difference. will continue treatments.
Our lawn is healthy and growing so well. Places around the edges where it was hard to grow grass are now filling in beautifully.
