Perfect Spike – Tree & Shrub Spikes – 5 pack
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.
