Know before you buy
Greensand works by physically altering the soil structure. It helps break up dense, compacted clay soils to improve drainage and aeration, while simultaneously helping sandy soils hold onto moisture and nutrients more effectively.
Yes, Espoma Greensand is an organic-certified soil conditioner. It is derived from naturally mined glauconite and contains no synthetic chemicals, making it a safe choice for edible crops.
Greensand is generally considered pH neutral and will not significantly alter the acidity or alkalinity of your soil. Its primary purpose is to improve soil structure and provide trace minerals like iron.
