Symptoms and Treatment of Deficiencies

Lutz Palm Tree Fertilizer Spikes have proven themselves unmatched in their ability to restore and hold healthy green growth in all established and transplanted Palms, and those with yellowing manganese, magnesium or potassium deficiencies.

Lutz Palm Fertilizer Spikes are a fast, efficient, long lasting method of fertilizing all Palms. Lutz Palm Spikes are applied next to the root ball, and slowly release nutrient to the Palm over several months. Depending on climate, annual or semi-annual applications are all that are necessary to maintain healthy green beautiful Palms.

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, Mn 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 Lutz Manganese Spikes per palm, depending on the size of trunk and severity of deficiency. Check the rate chart below.

Normal response is from 1 to 3 months.

Apply Manganese Spikes 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 Lutz Magnesium Spikes per palm, depending on the size of the trunk and the severity of the deficiency. Check the rate chart below.

Recovery can take several months.

Apply Magnesium Spikes 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, K and Mg should be applied together. Lutz Potassium Spikes contain a full 20% Potassium and 7% Magnesium. Potassium deficiency is common in most species of palms in Florida.

Treatment: Use 2 to 10 Lutz Potassium-Magnesium Spikes per palm depending on size of trunk and severity of the deficiency. Check the rate chart below.

Complete recovery can take a year or longer.

Apply Potassium Spikes anytime the deficiency is observed.

Maintaining Healthy Palms

Lutz Palm Tree Maintenance Spikes are a fast, efficient, long lasting method of fertilizing healthy palm trees. Lutz Maintenance Spikes have been carefully formulated to effectively fertilize your palms while protecting them from the common deficiencies of Manganese, Magnesium, Potassium, Iron and Copper.

Lutz Palm Tree Maintenance 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 theses vital nutrients to the feeder roots of your Palms.

For those Palms showing symptoms of Manganese, Magnesium or Potassium deficiencies, we suggest using one of the Lutz Spikes that have been specifically formulated to treat these deficiencies. These Lutz Spikes are: #30190 Manganese Sulfate Spike; #30191 Magnesium Sulfate Spike and #30192 Potassium Sulfate Spike. Treatments may be made any time these deficiencies are observed.

Once the deficient palms have responded to treatment we recommend maintaining them with the Lutz Maintenance Spikes.

Maintenance Spikes are applied every 4-6 months, depending on zone/location.
