Myth Using Gypsum for Lawns to Sweeten Soil

Myth Using Gypsum for Lawns to Sweeten Soil

Gypsum for lawns applied to the soil can quickly penetrate to the sub-soil area in the root zone where surface applied lime usually cant reach. Soluble aluminum toxicity damages root growth and decreases root penetration, thus affecting plant health. Only the few acid loving plant species blueberries, etc have high aluminum tolerances.
