Jack‘s Blossom Booster 10-30-20 4#

A professional formula for more flowers and brighter colors on geraniums, impatiens, begonias, marigolds, and all indoor and outdoor flowering plants. Feeds through both the roots and the leaves. Formula developed over 40 years ago for the professional orchid grower to help plants set abundant buds that matured fully into vibrant, beautiful, and colorful flowers. The 1-3-2 ratio is still the ratio that is preferred by professional growers when they want results. This formula also contains a higher level of magnesium, a vital secondary element, which helps keep leaves green.
