8-4-8 Tree Spike containing Iron, Manganese, Magnesium, Copper, Zinc, Boron and 13% Sulfur.
Lutz Ultra Tree Micro Spikes are ideal for all trees and shrubs, from Fruit, Citrus (that really thrive on the micros), to Evergreens, Maples, Birch and Oaks that require the Iron, Manganese and Sulfur.
Each 8-4-8 Ultra Tree Micro Spike contains the critical micro-nutrients required in all trees and shrubs. Plus a full 13% sulfur, which is critical to lowering pH, creating an environment in the feeding area that assists with the uptake of all the vital micro-nutrients.
Special binders slowly release the nutrients for up to 12 months. Lutz Ultra Tree Micro Spikes work underground at the feeder roots, to release these elements where the trees/shrubs get their nourishment. Easy, annual applications, provide superior healthy green growth! Check the rate chart here
Ultra Citrus Spike
Suggested Coverage & Placement of The “Ultra Tree” Spike
Place Spikes into moist soil, equally spaced around the dripline. Use 1 Spike per inch of trunk diameter (width).
For best results, place Spikes at least 3 feet apart at dripline, and never closer than 2 feet (24 inches) from trunk.
Hammer spikes to ground level using the plastic pounding caps. Remove cap and pound in at least two more inches.
In heavier soils, a cordless drill with a 1" auger bit is another popular method of easily creating holes for Lutz Spikes.
While all Lutz spikes are made to feed for up to twelve months, spring and fall feedings will give the maximum results.
