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.
Maple-Birch Spike
Suggested Coverage & Placement of The “River Birch” 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.
