20% Mn Sulfate
16% Sulfur

High pH is most often the factor in the yellowing manganese chlorosis often seen in Maples.

Specially formulated, the TreeHelp Maple Manganese Supplement Spike contains a full 20% Manganese Sulfate and a full 16% elemental sulfur, which lowers the pH in the feeding area, creating an environment that assists in the plant's uptake of the essential chlorophyll-producing manganese.  The small amount of nitrogen in the Spike also assists with this uptake. 

Symptoms of Manganese Deficiency:
Affects the new emerging leaves, manganese deficiency causes yellowing and necrosis between the veins and a reduction in leaf size.  As the deficiency becomes severe, the new leaves wither and have a "frizzled" look. If not promptly treated, manganese deficiency is often fatal to the red maple.

Specially formulated to provide manganese in a way your red maple tree can easily absorb, TreeHelp Maple Manganese Supplement Spikes will help bring your river birch and maple tree back to health.  The spikes can be used for both established and newly planted Maple trees.
