Like people, trees are susceptible to illness and disease. And like human diseases, tree diseases can quickly spread from tree to tree. While some trees manage to escape the worst of a disease, others prove more vulnerable. Protecting your Winona, MN, trees from diseases requires a fair amount of vigilance, especially if the disease in question is a fast-moving fungal one such as oak wilt. Our tree disease experts at Maier Tree and Lawn urge homeowners to keep their eyes peeled for signs of oak wilt so that if it occurs our tree health experts can step in and ensure a full recovery.

What Trees Are At Risk For Oak Wilt?

As the disease’s name implies, oak trees are the primary targets for this particular fungal strain. Red oaks are the most vulnerable, but white oaks can also be afflicted with oak wilt. Depending on the species of oak, the apparent symptoms may vary slightly or even quite significantly. Oak trees that are growing close to each other may also be at risk of spreading oak wilt depending on their underlying root structure. Staying on top of any visible signs is especially vital if you have a tree grove or a lot of trees on your property.

What Are The Signs Of Oak Wilt?

Oak wilt is transported primarily via the internal water transport systems of your trees. This means that it can spread very quickly and lead to wilting and discoloration. The wilting can occur as quickly as in four to five weeks. The tree’s leaves may turn brown or bronze starting from the outside and then inward. The leaves may also begin to drop as the tree becomes more ill.

What Should You Do If You Spot Symptoms Of Oak Wilt?

As soon as any symptoms are spotted, it’s important to act. Tree diseases such as oak wilt kill thousands of trees a year, and depending on the proximity and species of the trees on your property, it may spread rapidly among more than a single tree. Plus, oak wilt can also be transmitted via insects, which means that homeowners should not prune during the growing season. Immediately calling a tree disease professional after identifying a symptom of oak wilt is the best way to protect all of your trees.
