Palm tree resources

Palms appreciate moderate to heavy amounts of fertilization to keep their best color and to promote rapid growth. Spring, Summer, and Fall is the growing season for most palms, and this is when fertilizer will be most useful to the palm. We suggest a slow release fertilizer such as our Palm Pro granular or TreeHelp Palm Tree Maintenance Spikes. Also a quick acting foliar feed such as miracle grow can be applied in the early Spring to jump start the palms after the cool Winter hiatus. Specially formulated palm tree fertilizers target specific palm nutrient deficiencies such as Manganese Deficiency, Potassium Deficiency and/or Magnesium Deficiency.

Manganese Deficiency

  • Symptoms #1: 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.


  • Treatment: Use 2 to 10 TreeHelp Palm Tree Manganese Spikes per palm, depending on the size of trunk and severity of deficiency. Normal response is from 1 to 3 months. Treatments may be made anytime the deficiency is observed.


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.


  • Treatment: Use 2 to 10 TreeHelp Palm Tree Potassium Spikes per palm depending on size of trunk and severity of the deficiency. Complete recovery can take a year or longer. Treatments may be made anytime the deficiency is observed.

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.


  • Treatment: Use 2 to 10 TreeHelp Palm Tree Magnesium Spikes per palm, depending on the size of the trunk and the severity of the deficiency. Recovery can take several months. Treatments may be made anytime the deficiency is observed.
