WHY IS MY BUXUS TURNING ORANGE?

A thriving Buxus, also known as Boxwood, is a gardener's delight, boasting glossy green leaves that add structure and elegance to any landscape. But when these leaves start turning orange, it's a sign that something is amiss. Understanding the causes behind this color change is crucial for preserving the health and beauty of your beloved Boxwood.

Common Causes of Orange Buxus

1. Fungal Diseases

Fungal diseases, such as Boxwood Blight and Volutella Blight, are common culprits behind orange Buxus. These diseases thrive in warm, humid conditions and can spread rapidly, causing significant damage to leaves and stems.

2. Nutrient Deficiencies

A lack of essential nutrients, particularly nitrogen, magnesium, or iron, can also lead to orange leaves. Nitrogen deficiency typically causes older leaves to turn orange, while magnesium and iron deficiencies manifest as yellowing or orange spots between leaf veins.

3. Environmental Stress

Harsh environmental conditions, such as extreme heat, drought, or cold, can also cause Buxus leaves to turn orange. Inadequate watering, poor soil drainage, or exposure to strong winds can exacerbate stress, making your Boxwood more susceptible to pests and diseases.

4. Pests

Certain pests, like spider mites, boxwood leaf miners, and scale insects, can infest Buxus plants, causing leaves to turn orange or bronze. These pests feed on plant tissues, disrupting photosynthesis and leading to leaf discoloration.

How to Address the Problem

1. Identify the Cause

The first step towards resolving the issue is to determine the underlying cause. Carefully inspect your Buxus for signs of fungal diseases, nutrient deficiencies, pest infestations, or environmental stress.

2. Treat Fungal Diseases

If fungal diseases are the culprit, apply fungicides according to the manufacturer's instructions. Early detection and prompt treatment are crucial to prevent the spread of the disease and minimize damage to your Buxus.

3. Address Nutrient Deficiencies

Correct nutrient deficiencies by applying appropriate fertilizers. Choose fertilizers specifically formulated for Boxwood plants, following the recommended dosage and application schedule.

4. Mitigate Environmental Stress

Provide adequate water during dry spells, ensuring the soil remains consistently moist but not waterlogged. Mulch around your Buxus to retain moisture and protect the roots from extreme temperatures. Consider providing shade during hot afternoons to reduce heat stress.

5. Control Pests

If pests are the cause, use appropriate insecticides or miticides to eradicate them. Choose products specifically designed for the type of pest you're dealing with, following label instructions carefully.

Preventive Measures

1. Proper Cultural Practices

Healthy cultural practices go a long way in preventing Buxus from turning orange. Ensure proper spacing between plants to promote good air circulation and reduce the risk of fungal diseases. Prune regularly to maintain good plant architecture and remove diseased or damaged branches.

2. Monitor Plant Health

Regularly inspect your Buxus for signs of stress, pests, or diseases. Early detection and prompt action can prevent minor issues from escalating into significant problems.

Conclusion

Orange leaves on your Buxus can be a cause for concern, but with proper diagnosis and timely intervention, you can restore their vibrant green color and maintain a healthy, thriving plant. Remember, prevention is key, so follow good cultural practices and keep a watchful eye on your Buxus to prevent problems before they arise.
