Gypsum can be surface applied or tilled into the soil. For general lawn maintenance, apply 25 pounds of gypsum per 5,000 square feet to established lawns. Vegetable, herb, and flower gardens can benefit from 1 pound of gypsum for every 100 square feet of bed. For shrubs and small trees, apply 1 cup surround the base of the plant.
