Greensand 0-0-3 Mineral & Organic Fertilizer
Greensand is a long-term, slow-releasing fertilizer and minerals of marine origin with iron-potash-silicates, greensand loosens clay soils and increases the moisture holding capacity of both clay and sandy soil types. It holds up to one-third its weight in water. When added to container potting soil it will reduce the need to water as often. Our favorite source for potassium and minerals. We highly recommend greensand for vegetables, fruits, herbs, lawns, trees and shrubs. Used as an organic soil conditioner and fertilizer since the 1700's. 6 lb. box 25 lb or 50 lb bag.
