The mild weather with the appearance of the sun yesterday offered the perfect opportunity to prune the Oak trees in our meadow. Oak trees are one of the trees that you should avoid pruning during the growing season. Oak wilt is spread by the little black “picnic” bugs that may congregate on an open wound on the oak tree, and then the disease can migrate through the root system. Also, when roots of Oaks touch underground, they can spread Oak Wilt.
In late fall, winter or early in the spring before the arrival of our insect friends, you should plan on pruning your Oak trees. As always, be sure to wear eye protection. Please check out our library for articles provided from the Minnesota Nursery & Landscape Association on a variety of subjects – one being pruning.
