Start off by spreading 10 to 15 pounds of gypsum per 100 square feet of garden space. This is the sweet spot for most gardens, providing enough of the mineral to make a difference without going overboard. Once you've measured out the right amount, it's time to work it into the soil.
The gypsum board is fixed to the framing by a staggering adjacent layer of boards and perpendicular to the furring. Upon completion of the gypsum boarding to the frame, the joints are treated with the approved joint compound with a level 4 finish. The open joints and damages are pre-filled with the compound.

The granular or powdered form of gypsum specifically marketed towards garden use has a variety of different applications. Primarily, gypsum is used for helping to break up heavily compacted clay soils making them more porous and able to absorb moisture. This is particularly helpful in areas prone to drought. The addition of gypsum …
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name "gypsum" is derived from the Greek word "gypsos," which means "plaster" or "chalk.".
