A Letter from Jim Lutz - President of Lutz Corporation

Welcome! Lutz Corporation has been manufacturing and marketing the highest quality Tree and Shrub Spikes for over 20 years. Lutz Palm Tree Fertilizer Spikes have proven themselves unmatched in their ability to restore and maintain healthy green growth in transplanted Palms and mature Palms with yellowing manganese, magnesium or potassium deficiencies.

With recommendations from the University of Florida, Lutz Corporation began manufacturing our current line of Lutz Palm Tree Fertilizer Spikes used for decades around the world.

Lutz Corporation also manufactures Tree Fertilizer Spikes for all other trees and shrubs, including:

  • Perfect Spikes - our most popular and finest general purpose Fertilizer Spike on the market. An 8-10-10 Spike with Iron, Manganese and Sulfur.
  • Citrus Spikes - for properly feeding all Citrus trees. An unparalleled micronutrient package, so vital to quality citrus, includes Manganese, Magnesium, Copper, Iron, Boron, Zinc and Sulfur.
  • Iron Spikes - for treating Iron Chlorosis (yellowing) in many trees and shrubs in high pH soils. A 16% Iron Sulfate Spike with 4.8% Sulfur.
  • Maple-Birch Spikes - a 20% Manganese Sulfate, 16% Sulfur Spike for treating Red Maple trees and River Birch trees that often decline with manganese deficiency.

We are very proud of our line of Lutz Palm Fertilizer Spikes and Lutz Tree Fertilizer Spikes. Since 1990, Lutz Spikes have produced unequaled success in properly amending soils, restoring healthy green growth in all Palms, Trees and Shrubs.
