Do you have clay or layer of hard subsoil problems in your garden?

Then gypsum may be the answer to help loosen the soil structure.

What does Gypsum do?

It's main purpose is to penetrate the many clay particles in heavy or the layer of hard subsoil type soils and loosen the soil structure. Then this creates air and moisture slots that will loosen and break-up the soil structure. Just spread it on the lawn with a lawn spreader at the rate of 40 pounds per thousand square feet. Gypsum fertilizer can be spread any time of the year and only one application per year is needed. To get it started working, water immediately after applying.

What is gypsum?
