Treating Boxwood Decline: How to Save Your Shrubs

Boxwoods are beloved for their evergreen foliage and versatility in landscaping. However, boxwood decline has become an increasingly common problem among gardeners. This condition, also known as boxwood blight, can lead to the death of your shrubs if left untreated. But fear not! In this article, we will guide you through the steps to treat boxwood decline and save your beloved plants.

What Causes Boxwood Decline?

Boxwood decline is caused by a fungal infection that attacks the leaves and stems of the plant. The fungus can be introduced to your garden through infected plant material or contaminated tools. It thrives in warm and humid conditions, making it more likely to occur during the summer months. Once infected, the plant will start to show signs of decline, including yellowing leaves, black spots, and leaf drop.

Identifying Boxwood Decline

The first step in treating boxwood decline is to identify the problem early on. Look out for the following symptoms:

• Yellowing leaves
• Black spots on leaves
• Browning edges on leaves
• Leaf drop
• Dying branches

If you notice any of these symptoms, it's important to take action immediately to prevent the spread of the fungus to other plants in your garden.

How to Treat Boxwood Decline

Here are the steps to treat boxwood decline:

1. Prune affected areas: Start by pruning away any diseased branches or leaves from the plant. Be sure to sanitize your pruning shears with rubbing alcohol between each cut to prevent the spread of the fungus.
2. Fungicide application: Apply a fungicide to the plant according to the manufacturer's instructions. Be sure to cover all parts of the plant, including the undersides of leaves and the soil around the base of the plant.
3. Improve air circulation: Boxwoods thrive in well-ventilated areas, so make sure there is adequate space between plants and remove any debris or fallen leaves from around the base of the plant.
4. Watering: Avoid overhead watering, which can promote the growth of fungal spores. Instead, water at the base of the plant and avoid getting water on the leaves.
5. Mulching: Mulch around the base of the plant to help retain moisture and prevent weeds from competing with the plant for nutrients.

Preventing Boxwood Decline

Preventing boxwood decline is much easier than treating it. Here are some tips to help prevent boxwood decline:

• Plant boxwoods in well-draining soil
• Avoid planting boxwoods too close together
• Prune regularly to improve air circulation
• Sanitize tools between uses
• Avoid overhead watering

The Bottom Line

Boxwood decline can be a frustrating and devastating problem for gardeners. However, with proper treatment and prevention measures, you can save your beloved boxwoods from this fungal infection. Remember to act quickly at the first sign of symptoms and follow the steps outlined above to restore your shrubs to their former glory.
