Got A Dogwood Tree That Is Sick? 2 Common Diseases It May Have And How To Help

Dogwoods are beautiful trees when they flower in the spring and they can brighten up your yard. Therefore, if you have a dogwood tree that is showing signs of disease, you will likely want to learn what could be wrong with it so you can help bring back its health and beauty. Below are two common diseases your dogwood might have and how a tree trimming service can help alleviate the diseases.


If you have a Pacific dogwood (Cornus florida and C. nuttallii), it may have the anthracnose disease. This is a type of fungus infection that generally occurs during the wet spring months or cooler fall weather. However, it can happen anytime during its growing season. If you had a drought the previous summer, this can weaken the dogwood's ability to fight off diseases such as this.

The main symptom of this fungus is tan spots on the leaves. Over time, the leaves will curl up and may die. Fortunately, this fungus will not kill your dogwood tree, and it is only a cosmetic issue.  Applying a fungicide should take care of the problem. Make sure the tree stays watered during a drought season. Apply the water at the base of the tree so it gets down to the roots. Stick your finger a couple of inches into the soil surrounding the tree. If the dirt feels dry, then you need to give it some water.

Powdery Mildew

If your dogwood has powdery mildew you will see a whitish growth on the young shoots, buds, and leaves. Young trees are more severely damaged from powdery mildew than older, more established trees. Infected leaves may curl or look deformed. This disease can occur any time during the growing season. Fortunately, this issue will also not kill your tree and is a cosmetic problem.

A fungicide can also be used to control this disease. To prevent this from happening again during the next growing season, apply the fungicide once per year at the start of the growing season. 

Dogwood Tree Pruning

You should hire a tree trimming service to trim your Dogwood tree, which will lengthen its lifespan and improve the tree structure and vigor. Tree pruning will also reduce any structural problems, which can reduce the chances of contracting the diseases above. The tree service will also remove any dead, diseased, or broken branches to prevent fungi from spreading to other areas of the tree.

If the dogwood has a full crown, trimming back the branches will allow more sunlight to shine through the tree and increase air circulation, which will make it healthier.

The tree trimming service can inspect your tree for any problems so you can take care of them before they become worse. They can also tell you what type of fungicide you should purchase. For more information, contact a company like Mead Tree & Turf Care Inc.

Learning About Embracing The Natural Landscape

Hello, my name is Whitney Lovette. The property surrounding my home has a ton of natural hills and valleys that make mowing difficult. For a long time, I toyed with the thought of pulling all the grass and having an excavation team regrade my lawn. After some serious thought, I decided to take a different route and create a meandering garden space. The path through the garden takes advantage of the natural landscape to create a magical space for total relaxation. My site will cover the garden construction and upkeep process from beginning to end. Thank you for visiting my website.
