Jack's Classic Acid Special 17-6-6 Fertilizer 4LB

Water soluble. Very effective in reducing the soil pH, which keeps iron and other trace elements available to the plant. In plantings next to the concrete foundations of the home, where the pH is elevated, it will keep the leaves green and healthy, promoting lush vegetative growth and better blooms. This formula contains elevated levels of iron and sulfur which most of the acid loving plants require.
