Tree Health Trees are an important part of the landscape, but there are a variety of factors that can cause them to be unhealthy or even die in some cases. The challenge with diagnosing tree problems is that there can often be more than one factor involved. There is information on this site that will teach you how to evaluate your sick tree, how to collect needed background information, and how to contact local and state experts for assistance. There is also information on a variety of common insect and disease problems found on trees in Iowa. Off-Site Web Resources
Posted: March Dear TreeTalk: I live in an older neighborhood with very large established oaks in the yards of most of the homes. In the last few years a number of the oak trees have died each summer. These trees start dropping brown leaves in late June/Early July and they usually die within 6 to 8 weeks. Someone told us that there is a new oak disease that is causing oak trees to die all over the state, and most likely all of our oak trees in the neighborhood will be dead in the next few years. I have 2 large red oaks, 1 white, and 1 bur oak in my yard and I am wondering if there is anything I can do to protect these trees from this new disease? - Cindy from Cedar Rapids
