Rated 4.6 out of 5 by 5 reviewers.
Rated 4 out of 5 by Great for soil, but has many small stones in it. Gypsum is the magic ingredient for clay soil. It improves drainage, tilth, soil structure. This is a raw ore product, brownish with many small stones (2-3 cm) in it. It would be fine for garden use or preparing soil for a lawn, but if you use it on an established lawn, you have to rake the pebbles out afterwards. The price is great though. Another big hardware store in town has pure powder gypsum, 50# at about twice the price. It's absolutely indispensable for soil preparation here with our high clay soil. Without it plants just sit. They can't push their roots thru the soil. May 4, 2014
Rated 5 out of 5 by Outstanding Product I purchased this on the advice of someone and could not be more satisfied with the results I achieved. My soil is an extremely hard clay. I planted eight palm trees and used a jack hammer to get through the soil. The first two holes took two hours to dig. I mentioned it to someone and they told me about this product. I used it at about three times the recommended ratio and the results are phenomenal. It seems like the hard soil is now a top soil. It broke up that nasty clay unbelievably. I am loving this product.

Rated 5 out of 5 by Great Product The earth is compacted clay in my yard. I use this product to loosen the clay and allow water to drain. Once you add the gypsum and water, the earth becomes porous and allows plants to drain. It is an amazing product. I use this every time I plant something. I bought a new home with no landscaping in the rear yard. I add this to the soil and overnight it breaks up the soil, so your plants can thrive. April 10, 2012
Rated 4 out of 5 by It works, it just takes time. Purchased this to counter urine burn (thanks to my dog). I found various suggestions for this product. I must say, the grass is in better shape, just give it a few weeks. Will definitely have some in stock. October 29, 2010
Rated 5 out of 5 by great product. I found out about this product by accident, this product will help if you have clay soil, gypsum will work faster than steer manure, this product will work immediately, your soil will be soft, I am very happy home depot carries this product, it is wonderful.
