MYTH: Gypsum Changes the pH of Growing Media

Gypsum is ground up rock that has a gritty to powdery feel. Depending on how finely ground it is, it can provide plants calcium and sulfate for 1-2 months and is typically applied at 1-2 lb/yd 3 (0.6-1.2 kg/m 3) of soilless growing medium. Gypsum is one of the few sources of calcium that does not cause the pH of growing media to rise.
