(PDF, 1 pg, 106 KB) May 2016
In traveling around southeast Nebraska I am seeing a number of trees in the area showing signs of iron chlorosis. This is the condition when the leaves of trees are more yellow than normal. In the drought conditions southeast Nebraska has experienced in recent years trees are under a great deal of stress. Anything that can be done to reduce stress on trees will be beneficial to the tree, especially in the long-term, and also reduce the likelihood of attack by insects and diseases. The most common trees associated with iron chlorosis are pin oaks and silver maples. . . . (Learn more, PDF, 1 pg, 106 KB) May 2016

(PDF, 1 pg, 104 KB) March 2015
Why prune? This is a good time to correct minor structural problems a tree may have and remove branches that are broken, rubbing or crossing each other. If you cut some of the smaller branches back to the trunk, this will help direct growth into the terminal leader and larger lateral branches, helping the tree develop a strong foundation. . . .
