Hi-Yield® Magnesium Sulfate 4lb - Granules Hi-Yield® Manganese Sulfate is a product formulated with agricultural-grade Epsom salt, which is a soluble source of magnesium.

This readily available magnesium helps correct plant chlorosis, making it an excellent choice for use on palms and other plants.

Additionally, it can be used to encourage white blooms on hydrangeas.

For application, you can use a foliage spray by mixing 2 tablespoons per gallon of water.

Alternatively, for soil application, use 1 pound per 100 square feet to ensure your plants receive the necessary nutrients for healthy growth and vibrant blooms.
