How to Use

 

Jack's Classic African Violet has been a long time favorite formula for home and hobbyist growers of these beautiful flowering plants. Its high phosphorus levels encourage root and bud development for deep green vegetative growth and vivid and bright color expression on the blooms.

 

For feeding your African violets indoors, use 1/4 teaspoon per gallon with every watering or 1/2 teaspoon per gallon every other week. You can make up a gallon jug of the fertilizer mixture and keep it stored in a low light, cool area until next use. Be careful not to overwater these plants. Instead, use specific pots that allow the plants to be fed from the bottom, thereby using what they need and keeping a nice supply for later. In high light conditions, you can double these rates, which will create vigorous growth.

 

For those who prefer a non-urea based African violet fertilizer, use our Jack's Classic Blossom Booster 10-30-20!

 

This product can also be used outdoors (1 tbsp. per gallon) as a transplant solution and as a blossom booster for all flowering plants, especially hanging baskets.

For Best Results

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

 

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
