This product is specially formulated for those chronically iron-hungry crops such as petunia, calibrachoa, bacopa and others. The original Jack's FeED product designed with all three iron chelates, EDTA, DTPA and EDDHA. Our proprietary blend of iron level is unmatched by any competitor and guaranteed to deliver iron at a much broader range of pH over the entire crop cycle. This nutrient profile is also paired with a low phosphorus level to help prevent excessive elongation. It is not recommended for use on geraniums or other iron sensitive crops.

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. The additional 2% Nitrogen in the formula reduces your fertilizer usage by approximately 10%, making this product not only nutritionally effective, but cost effective as well.
For use on: Garden Mums, Iron loving warm weather plants
