Maple-Birch Spike

The Lutz Maple-Birch Tree Spike is the ideal fertilizer for feeding Maples, River Birches and other manganese deficient trees and shrubs and are specially formulated to solve deficiency problems that most often prevent good green-up and sound growth.

As high pH is often a factor in manganese deficiency, each spike contains 16% elemental sulfur which lowers pH in the feeding area, creating an environment that assists the plants’ uptake of the manganese.

Once the spikes are installed in the root zone, special binders safely and uniformly release elements for up to twelve months.
