Palms have the most distinctive nutrient profile in the landscape: they are famously hungry for magnesium and manganese, and the yellowing older fronds and frizzled new growth that plague palms are almost always those two deficiencies, not disease. Our Palm Tree Fertilizer delivers the complete program, supported by Epsom Salt and Sulfate of Potash Magnesia for magnesium, Manganese Sulfate and chelated manganese for correcting frizzle top, and chelated iron for tropicals in alkaline soil. Every product is CDFA registered, third-party tested for heavy metals, and made in our FDA-registered Madera, California facility.
