| Controlled release Aluminum Sulfate designed to be used primarily as a soil amendment to promote the development of blue flower colors in hydrangeas. Manufactured by X-calibur Plant Health Company LLC. This unique polymer coating technology controls the release of both the sulfur and the aluminum and thus reducing the need for multiple applications and providing a steady release into the growing media. Controlling the release of sulfur helps prevent the fluctuations and or the rapid drop in soil pH which not only affects the nutrient availability, but will reduce the potential for aluminum toxicity. Controlling the release of aluminum helps prevent nutrient imbalances and also reduces the potential for aluminum toxicity. 2 pound bag
