Potassium Spike – Pack of 5

$25.00

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.
