        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.

    • How to Use


      For Outdoor plants: 1 tbsp. per gallon of water; for outdoor trees and shrubs feed every 10-14 days.azalea

      For Indoor plants: 1/4 tsp. per gallon of water as a constant liquid feed program

      For acidification and green-up: The normal recommended dosage is 1 tbsp. per gallon, equal to about 3 lbs. over 100 gallons. Only a few applications will be needed to effect the needed pH change.

       

      Use of this formula should be limited to temperature ranges that do not fall below 45 F°. Best results, follow the program above in the normal spring, summer and fall growing seasons.

       

      For small volume mixing:

      Dissolve the following amounts in 1 gallon of water. Injectors should not be used.

      1/2 tsp.  =   135 ppm

      1 tsp.     =   260 ppm

      1 tbsp.   =   780 ppm

       

      When using a Siphonex or Hoze-on proportioner

      100 ppm    =    1.0 oz.               0.64

      200 ppm    =    1.9 oz.               1.28

      300 ppm    =    2.9 oz.               1.92

      Limit of Solubility in Hot Water = 4.0 lbs. per gallon

       

      For Best Results

      Jack's Fertilizers are made with 100% soluble raw materials that will form a true solution. 

       

      For best results, use warm or hot water (180 F°) to dissolve product. Some raw materials are slower to dissolve than others. Most fertilizer compounds dissolve in an endothermic reaction, which means they absorb heat from their surroundings during the process. In strong concentrations or stock solutions (1-3 + lbs. per gallon), using cold water in a cold environment will drastically slow the dissolving process (up to 24 hours to form a true solution). In all conditions, agitation will help speed up the dissolving process by exposing more particle surface area to the water.
