Leaves on my maple tree have turned yellow, but the veins are green. Is this an iron problem?
Rate This FAQ
Most likely. Iron chlorosis is the most common micronutrient problem in our area. There is abundant iron in our soil. However, due to the high pH (alkaline soil) it is unavailable to some of our plants. In advanced stages of iron chlorosis, leaves turn yellow between green veins. Chlorotic areas may then scorch and die back. Without iron, the plants cannot manufacture chlorophyll, the green stuff of leaves. Peaches, apples, raspberries, roses and many other plants are affected by this problem. Iron chlorosis may be aggravated by heavy soils, overwatering, and high levels of phosphorous in the soil.
Recommendation: In early spring (before leaf break) apply iron chelate near the plant roots. If iron chlorosis persists during the summer, spray leaves with a liquid formulation of chelated iron, but never during the hot part of the day. Follow all label directions.

- I am an architect, working with a client who wants to hydroseed a 2.5 acre parcel for use as a softball field. The area is currently planted in alfalfa. There will be some regrading (both cut and fill) of the field that will be required. The client would still like to hydroseed this year, likely near the end of September. Do we need to call for the alfalfa to be treated with a herbicide? If so, what is the process, and what herbicide should be used? Is there a waiting period between application of the herbicide and the hydroseeding? Must the herbicide be applied to the above-grade plants, or can the site first be cleared, then the herbicide applied to the gound and roots?
