A couple weeks ago, we announced the launch of Mn-jet Fe™, our new liquid micronutrient solution to fight interveinal chlorosis. Iron chlorosis is “interveinal,” meaning the yellowing occurs in leaf tissue between the leaf’s veins. Hot weather or dry soil conditions will result in a reduced rate of uptake, so trees should be watered if applications are made when soil is extremely dry.

For trees, chlorosis may be treated by implanting into the trunk capsules containing solutions of the needed micronutrient. Fall is the best time to reintroduce these nutrients. Make applications prior to bud break in spring or, alternatively following leaf maturation (June 15). Soil treatments, spraying applications of micronutrients to foliage, and trunk injections merely treat the symptoms and not the basic causes of chlorosis. If the chlorosis is due to soil compaction, poor drainage, poor root growth or root injury, then core aerification, tiling, mulching or some other cultural practice may be needed.
