As spring approaches, many homeowners start to plan their gardening and landscaping projects. One popular tree species that is commonly used in these projects is the dogwood tree. However, if not properly taken care of, dogwood trees can be susceptible to a disease known as dogwood blight. In this article, we will discuss how to identify, prevent, and control dogwood blight.

What is Dogwood Blight?

Dogwood blight is a fungal disease that affects dogwood trees. It first appeared in the 1970s and has since spread to many parts of the world. The disease is caused by the fungus Discula destructiva, which attacks the leaves, twigs, and branches of the tree.

The initial symptoms of dogwood blight are small purple spots on the leaves. As the disease progresses, the spots enlarge and turn brown or black. Infected leaves may also curl and fall off prematurely. The disease can eventually kill the entire tree if left untreated.

The best way to deal with dogwood blight is to prevent it from occurring in the first place. Here are some tips for preventing dogwood blight:

Choose healthy trees: When purchasing dogwood trees, make sure they are healthy and free of any signs of disease.
Plant in the right location: Dogwood trees prefer partial shade and well-drained soil. Avoid planting them in areas that are prone to standing water.
Avoid injury: Be careful when mowing or trimming around dogwood trees, as injuries to the bark can create an entry point for the fungus.
Practice good hygiene: If you have infected dogwood trees on your property, make sure to clean up fallen leaves and branches to prevent the fungus from spreading.

Treating Dogwood Blight

If you notice signs of dogwood blight on your trees, there are several steps you can take to control the disease:

Apply fungicides: There are several fungicides available that can help control dogwood blight. Follow the instructions carefully when applying these products.
Avoid overhead watering: Watering the tree from above can create conditions that are ideal for the growth of the fungus. Instead, use a drip irrigation system or water the tree at ground level.
Improve air circulation: Pruning the tree to improve air circulation can help reduce the risk of fungal infections.
