Common Tree Diseases in the Twin Cities Area

At Bratt Tree, our mission goes beyond simply providing tree services. We are deeply committed to fostering a community that’s well-informed and proactive in maintaining a healthy environment.

Both homeowners and commercial property managers play a pivotal role in this endeavor. By understanding and identifying the prevalent tree diseases in the Twin Cities, they can take timely action to prevent further spread and ensure the longevity of our urban green spaces.

Dutch Elm Disease

The infamous Dutch Elm disease is a fungal affliction that can quickly devastate elm tree populations. Introduced by an invasive bark beetle, it strikes regardless of a tree’s age or location. Early detection through wilting or yellowing leaves can be vital. Our ISA Certified Arborists at Bratt Tree Co. can help with preventative pruning and, when necessary, remove infected trees to prevent the spread.

Oak Wilt

Like the Dutch Elm disease, Oak Wilt is a fungus that spreads through root systems and insects. Found predominantly in red and pin oaks, this disease can be challenging to manage due to the vast interconnected root networks of oak trees. Proactive measures include sealing pruning wounds immediately and maintaining healthy soil conditions. If you notice leaves browning in summer, we can help with a consultation on managing this threat.

Emerald Ash Borer

Emerald Ash Borer is a highly invasive pest that’s decimating ash trees throughout Minnesota. If not proactively addressed, this destructive insect could wipe out most of the state’s ash population. Regular tree inspections by our trained technicians are essential to early detection and prevention.

Apple Scab

Primarily affecting apple trees and crabapples, Apple Scab is a fungal disease causing dark, scaly lesions on leaves, fruit, and twigs. Fungicide treatments in early spring and regular cleanup of fallen leaves can help prevent this disease.

Pine Wilt

Pine Wilt, caused by a microscopic worm (nematode), primarily affects non-native pines and can kill a tree within a few months. Infected trees must be removed and destroyed quickly to prevent the spread. Early detection is critical and can be identified by rapid wilting or browning of needles.

Cytospora Canker

Often targeting stressed or injured trees, Cytospora Canker is a disease that can lead to branch death and disfiguration. It can affect various tree types but is particularly common in spruce and poplar trees. Pruning infected limbs and maintaining good tree health can aid in prevention.

Other Pests That Can Harm Your Trees

Pests can pose significant threats to our Twin Cities’ trees, affecting both their health and aesthetics. Among these, two noteworthy pests are the Gypsy Moth and the Japanese Beetle, both known for their devastating impact on a variety of tree species.

Gypsy Moths, invasive pests with a voracious appetite, can defoliate large sections of trees, causing stress and potentially death. Larvae, identified by their distinctive blue and red dots, munch on leaves, favoring oak, poplar, and birch. Repeated infestations can severely weaken trees, making them susceptible to other diseases. Preventive treatments include insecticides, pheromone traps for male moths, and removing egg masses before they hatch. Our trained technicians can assess the extent of the infestation and recommend the most effective treatments.

Japanese Beetles, identifiable by their metallic blue-green heads, pose a dual threat. While the adults consume leaves and flowers, leaving a lacy skeleton, their larvae, or grubs, feed on roots, damaging the overall health of the tree. Frequent victims include linden, apple, plum, and birch trees. Preventive measures range from hand-picking beetles to applying systemic insecticides. A healthy, well-watered tree can often withstand a beetle attack, emphasizing the importance of regular tree health maintenance.
