Dealing with Boxwood Plant Diseases:
Identification and Treatment

Boxwood plants are a popular choice for landscaping due to their evergreen foliage and versatility. However, they are susceptible to various diseases that can cause damage to the plant and affect its overall appearance. In this article, we will discuss common boxwood plant diseases, how to identify them, and effective treatment options.

Common Boxwood Plant Diseases

Boxwood Blight

Boxwood blight is a fungal disease that causes rapid defoliation and stem cankers in boxwood plants. It is highly contagious and can spread easily through contaminated soil or tools. The disease first appears as brown spots on the leaves, which quickly turn black and cause the leaves to fall off.

Volutella Blight

Volutella blight is another fungal disease that affects boxwood plants. It typically appears in warm, humid weather conditions. The first symptoms of volutella blight include small brown spots on the leaves, which eventually turn into larger brown patches with a pinkish mold on the underside of the leaves.

Root Rot

Root rot is a common disease that affects many types of plants, including boxwood. It is caused by a fungal infection that attacks the roots of the plant, leading to stunted growth, yellowing leaves, and wilting.

Boxwood Leaf Miner

Boxwood leaf miner is an insect pest that causes damage to the boxwood plant by burrowing into the leaves and causing them to turn brown or yellow. The larvae of the leaf miner feed on the inside of the leaves, causing them to curl and distort.

How to Identify Boxwood Plant Diseases

The first step in identifying a boxwood plant disease is to inspect the plant regularly for any signs of damage or abnormality. Look for discoloration or spots on the leaves, wilting or stunted growth, and any signs of insect activity.

If you suspect a disease or pest infestation, take a closer look at the affected areas. Look for any signs of fungal growth or insect activity. You may also want to take a sample of the affected plant parts and bring them to a local nursery or garden center for further analysis.

Treatment Options for Boxwood Plant Diseases

The treatment options for boxwood plant diseases depend on the specific disease or pest infestation. Here are some common treatment options:

Fungicides

Fungicides are often used to treat fungal diseases such as boxwood blight and volutella blight. They work by killing off the fungi that are causing the disease. Fungicides should be applied according to the instructions on the package.

Insecticides

Insecticides can be used to treat pests such as boxwood leaf miners. They work by killing off the insects that are damaging the plant. Insecticides should be applied according to the instructions on the package.

Soil Amendments

Soil amendments such as compost or organic matter can help improve soil health and prevent root rot in boxwood plants. They can also help improve drainage and prevent waterlogging in the soil.
