Jack's Professional 22-5-16 Mum FeED -
Mums are heavy feeders that respond well to additional magnesium, sulfur and iron. Many times though, the iron becomes unavailable as the pH rises. The elevated iron levels found in the exclusive FeED iron chelate system keeps the iron available to the plant even if the pH rises during the crop cycle.
Jack's Professional 15-4-15 Poinsettia FeED CaMg -
This product is designed to fit the needs of the newer poinsettia cultivars that require micronutrients, but a lesser amount of macronutrients. The specialty FeED package keeps iron available at a broader range of pH plus extra Molybdendum and lower B. This formula is a Cal-Mag and should be used to supply extra Calcium and Magnesium.
