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 have a son that lives in west Eagle Mt. We Put in sod for a lawn about two years ago and for two seasons it did great. Half of it is now dead and the other half is struggling. Prior to putting down sod, the ground was thoroughly tilled and lots of compost material was added (the kind that is made available in some green recycling yards and mixed with treated effluent from the sewage treatment plant.) Nitrogen was also added to the soil and the lawn was watered regularly. What has happened and what can I do to get a good lawn here?

I have heard of grubs, however I have no idea how to identify what is going on with the grass or how to treat it. You can pull up larges patches of grass easily, there don't appear to be any roots in some areas and I would like my grass to be pretty again. What can you recommend?
