        Perfect for greening up all acid loving garden and houseplants. Feeds through both the roots and the leaves.

         

        Jack's Classic® Acid Special 17-6-6 is 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.

    • Tips in using Jack's Acid Special

      Acid Special is best used as a root drench especially for planting next to concrete foundations of the home or other areas where soil pH may be elevated. 

       

      Application with Acid Special will be more effective than using the same rates of our 20-20-20 when concerned with lowering pH as well as greening plant leaves. The acidifying power of 17-6-6 is approximately 1600 lbs. calcium carbonate equivalent acidity—compared to the only 1000 lbs. equivalent acidity for most other common “acid” fertilizers.

       

      This product will promote lush vegetative growth and better blooms through its enhanced nutrient package, which includes elevated levels of iron and sulfur.
