River Birch/Red Maple Spike - 20% Manganese cures yellowing Mn Chlororsis

High pH is most often the factor in the yellowing manganese chlorosis often seen in Maples, Birch and other manganese deficient trees and shrubs.

We formulated the Lutz Maple/Birch Spike to contain a full 20% Manganese Sulfate. Then we add a full 16% elemental sulfur, which lowers the pH in the feeding area, creating an environment that assists in the plaints uptake of the essential chlorophyll producing manganese. The small amount of nitrogen in the Spike also assists with this uptake.

Low Cost – Highly Effective – Easy to Apply

Suggested Coverage and Placement

Place one Lutz Maple/Birch Tree Spike every four feet at the outer edge of the dripline. If deficiency is severe, reduce spacing to 3.5 feet.
Spikes can be either pounded into the ground using plastic caps provided, or dropped into the root zone, using the Lutz Fast/Feeder to make 8-inch deep openings. Heel the holes closed.
