Fertilizing Palm Trees

Most landscape palms will require fertilization once or twice during the growing season. Not just any fertilizer will do, however. Palm trees have special needs that must be met with specially formulated fertilizers that target specific nutrient deficiencies. Homeowners should also apply regular maintenance fertilizers to healthy trees. Most landscape palms will require fertilization once or twice during the growing season.

Palm Fertilizer Spikes are a fast, efficient, long lasting method of fertilizing palm trees and, in most situations, would provide all the nutrients your palm trees would need. These palm spikes have been carefully formulated to effectively fertilize your palms while protecting them from the common deficiencies of Manganese, Magnesium, Potassium and Iron
Palm Fertilizer Spikes contain Nitrogen plus soluble Manganese, Magnesium, Potassium, Iron and Copper Sulfates. Their release has been slowed by the use of proprietary binders to safely release the nutrients to the feeder roots of your Palms - right where they are most effective. Each spike provides exact measured amounts of these fertilizers so palms can be properly fertilized by using the correct number of spikes according to tree size.
Manganese Deficiency
Symptoms: Affects the new emerging leaves, causing yellowing and necrosis between the veins and a reduction in leaf size. As deficiency becomes severe, the new leaves wither and have a "frizzled" look. If not promptly treated, Manganese deficiency is often fatal to the palm. Manganese deficiency can affect most species of palms. Queen, paurotis and royal palms are particularly susceptible.
Potassium Deficiency
Symptoms: Causes yellow, orange or brown flecks and necrotic margins of older leaves. Withering ("frizzling") begins on these older leaves first. From a distance these leaves often appear brown or orange in color. If deficiency is severe enough, new shoots will eventually be affected. If unattended, the palm may die. Curing the potassium deficiency can lead to magnesium deficiency. To balance, potassium and magnesium should be applied together. Potassium deficiency is common in most species of palms in Florida.
Magnesium Deficiency
Symptoms: Affects the older leaves, causing them to yellow at the edges while the center band stays green. In severe cases leaflet tips also become necrotic. Magnesium deficiency can affect most species of palms. Date palms are particularly susceptible.
