Lutz Ultra Tree Micro Spikes

Lutz Ultra Tree Micro Spikes, 8-4-8 with B, Fe, Mn, Mg, Cu, Zn, and 13% S, Pack of 5

Ideal for all trees and shrubs, these 8-4-8 spikes contain critical micro-nutrients. The 13% Sulfur lowers pH to help create an environment in the feeding area that promotes the uptake of essential micro-nutrients. Special binders slowly release nutrients for up to 12 months. These spikes work underground at the feeder roots, meaning that valuable nutrients won’t be washed away. Place spikes in moist soil, equally spaced around the dripline. Use one spike per inch of trunk diameter (width). Pack of 5.
