Iron Spike

Lutz Iron Chlorosis Spikes treat Iron Chlorosis (Yellowing) in Pin Oak, White Oak, Rd Oak, Silver Maple, River Birch, Pines, Crabapple, Sweet Gum, Magnolia, Dogwood, Holly, Poplar, Juniper, Rhododendron, Azalea, and all other acid-loving Trees, Shrubs and Plants.

Iron is necessary for the formation of chlorophyll, which is responsible for the green color in plants and is a source of plant food and energy. When the amount of iron available to plants is inadequate for normal growth, leaves become pale green, yellow or white, eventually brown and die. The newest foliage is most severely affected by iron chlorosis. If not corrected severely affected plants may fail to grow, flower or fruit.

Lutz Iron Spikes are the ideal soil amendment for iron poor plants

Soil pH is most often a factor in Iron Chlorosis. Se we put a full 4.8% Sulfur in our Iron Chlorosis Spike, which creates an environment in the feeding area that frees up the iron, which is in a form readily available to the plant. The 5% Nitrogen also assists with the uptake of all nutrients, but most importantly the 16% iron sulfate we have in the Iron Chlorosis Spike.

Favorable color responses are often seen the 2nd growing season. Amending iron chlorotic soils is a process, so annual applications are recommended, semi-annual applications if iron deficiency is severe. Greatest color response is seen with the onset of new leaf.
