Is it just gypsum (calcium sulfate dihydrate) or are there other chemicals/fertilizers added to this product? I want an ingredients list
Asked by: Corey
Hello, Pennington Fast Acting Gypsom is 96.5% gypsum. It also contains Advanced Soil Technology (AST). AST helps by binding nutrients to the soil which prevents them being lost by the runoff of surface water. Thank you

Can this be used for trees?

Asked by: Kate1123
This is going to breakdown the soil of your yard so it can get the proper nutrients. It’s not going to hurt your tree, if that’s the concern.

Rated 4 out of 5 by from very necessary for my soil well honestly what can you really say about gypsum? it came super fast with free shipping. it breaks up clay so that your water gets to the roots of your lawn or garden. it was very easy to order without having to go search for it at my local store which never has anything i want anyway. i love home depot online.

Rated 4 out of 5 by from Works as designed It takes a couple of applications over a few months to really start seeing the difference but it is a great product to use in the summer when regular fertilizer would burn the grass. Suggest that frequent watering would push along the soil enhancement even further.

It doesn't help that the developer stripped ALL the top soil. Gypsum is supposed to help break up clay. After applying it to the entire property, not just the lawn, for a few years it certainly doesn't seem to hurt and may be helping. We now have topsoil at least an inch thick. Gypsum for the garden is getting harder to find, even at garden centers. This is easy to obtain; order online, pick up at the store when convenient.

Rated 4 out of 5 by from Good product great service Gypsum works like it should. It will take several weeks and applications to see strong results. Ordered online. And had delivered to local store for free delivery. It arrived about a week early.
