Our take on the Jack's Classic 20-10-20 Citrus Food Water Soluble Fertilizer

Jack's Classic Citrus FeED is a water-soluble powder fertilizer with a 20-10-20 NPK ratio plus added micronutrients, blended for citrus and other tropical plants. It dissolves in water and can be applied as a root drench or a foliar spray, and each tub includes a measuring scoop. The high nitrogen and potassium push leafy growth, strong branches and fruit set, while the phosphorus is modest. Compared with general-purpose all-purpose fertilizers, it is tuned for container and in-ground citrus, and the 27 ratings average 4.9 out of 5.

Questions and answers
