Perfect Spike

Perfect Tree Fertilizer Spike

How the 8-10-10 “Perfect” Spike Works

The Lutz “Perfect” Spike was formulated to solve the deficiency problems that most often prevent good healthy green-up and sound growth. Each “Perfect” Spike contains 4.8% combined Sulfur (S), 3.3% Iron Sulfate (Fe) and 3.2% Manganese Sulfate (Mn). This compares with 0% of these critical elements in most other tree and shrub fertilizers

As Dr. Henry Donselman says, “Trees and shrubs require sulfur, iron sulfate and manganese sulfate for good healty growth. N-P-K spikes without these minors do not fill the nutritional needs of trees and shrubs.”

  • Elemental sulfur in the “Perfect” Spike lowers the pH in the feeding area, creating an environment that assists the plants uptake of the manganese and iron.
  • Special binders safely release the elements over time. It takes up to 12 months for the “Perfect” Spike to completely dissolve.
  • Lutz “Perfect” Spikes work underground at the feeder roots to release the elements where the trees and shrubs get their nourishment. They can’t wash away like surface applications.
  • Lutz “Perfect” Spikes help overcome the deficiencies of N-P-K only spikes.

We expect you will be more than pleased with the results you get from The “Perfect” Spike.
