Don’t Prune These Trees in Summer

There are specific guidelines when it comes to tree pruning. While trees require routine maintenance for overall health and safety, there are specific seasons that trees should not be pruned. While you may have an overgrown tree, deadwood or just need general pruning, it is important to note that not all species of tree can be trimmed year round.

Oaks, pine and birch trees should not be trimmed during the hot summer months. Oaks trimmed during extreme heat are susceptible to oak wilt disease which can quickly kill the tree. Oak wilt is transmitted via beetles that carry the disease and dine on open wounds on the tree. The infected tree can transfer the disease to nearby oak trees via beetles and the trees root system if in the trees are in close proximity.

Pine trees should also be on your do … Read More »

Dutch Elm Disease

Arbor Masters® Certified Arborists have noticed a dramatic increase in Dutch elm disease in the Kansas City metro area. Dutch elm disease is caused by a vascular wilt fungus, which is carried from diseased trees to healthy trees via the European elm bark beetle and the native elm bark beetle. The fungus can also be transmitted from one elm to another via root grafts. Trees planted within 25 to 50 feet of each other can easily develop grafted root systems and quickly spread the disease.

Symptoms include yellowing leaves on the branch tips which then turn brown and curl up. These brown leaves which remain on the tree for some time, are called “flags” and their appearance in an otherwise green crown is called “flagging.” As the disease progresses, more flags will appear until the entire crown becomes diseased. Symptoms on infected trees develop quickly within a 4-5 … Read More »
