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.
For use on: Petunia, Calibrachoa, Bacopa

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

Jack's Geranium 15-15-15 is well known as Dr. Cari Peters' favorite formula. An ideal fertilizer for geraniums and other neutral pH loving plants. Dr. Cari spent a significant portion of her Masters and PhD program studying the effect of nutritional imbalances in many different types of geraniums. After all that time, she still believes in the simple strength of this formula.
The high phosphorus content promotes strong root growth and bud set in the plant (also, great for pink hydrangeas). The high nitrate nitrogen content (56%) and the general-purpose level of micronutrients help minimize nutritional toxicities on geraniums.
This formula grows fantastic geraniums when you have a good source of calcium already in your water source. Its slightly acidic nature keeps pH on the downward trend without causing pH drop out in the plant root zone.
*Note*--if water source does not have over 40 ppm Ca, or is slightly acidic, growers can use this formula as an alternate with the standard 15-5-15 and still see many of the greening and blooming effects we love from the Geranium 15-15-15.
