Iron/Manganese

Trees suffering from slow or incomplete leaf-out? Trees looking yellow or tired? Help trees green up fast with Iron and Manganese Nutriboosters.

Indications

Relieves symptoms of iron chlorosis, the general yellowing of foliage. Works most effectively on Oak trees. Effectiveness on other varieties of trees may vary.

• Iron deficiency in deciduous trees is indicated by yellow leaves. The degree of yellowing indicates the severity of the deficiency. If fine veins become chlorotic (yellow), and/or if leaf edges are wavy, crinkled, or curled, the tree may also have manganese deficiency.
• Iron deficiency in conifers is indicated when the needles turn yellow.
• Ornamental trees sensitive to iron deficiencies include American Elm, Cottonwood, Jack Pine, London Plane Tree, Magnolia, Maples, Mountain Ash, Oaks, Walnut, White Pine, and Yellow Birch.
• Ornamental trees susceptible to manganese deficiencies include Birch, Dogwood, Maples (especially Red and Sugar), Flowering Cherry, Sweetgum, and Sergeant Crab.

Application Rate

Inject 1 ml every 4” around the base (flare) of the tree. See label for details.

Timing of Nutribooster Injections

Injections may be made any time during the growing season. However, as summer ends, green-up will be less likely to occur because the leaves become less responsive as they age. The best time to inject is spring through early summer.
