Why is my Bay Tree dying?

Bay trees are one of the most beloved evergreens in UK gardens. With their deep green foliage, subtle fragrance and classic structure, they bring form and flavour to outdoor spaces year-round. But if your bay tree is looking lacklustre, don’t panic, it’s often a case of identifying the issue and applying the right care.

Here are the five most common reasons bay trees begin to struggle and what you can do to bring them back to health.

These are the top 5 reasons why your Bay tree might be dying:

1. Lack of water

Bay trees prefer evenly moist soil. If their roots dry out (particularly in containers) you may notice browning or dropping leaves. Check the soil regularly. If it’s dry a few centimetres below the surface, it’s time to water. During hotter months, potted bays may need watering more frequently than you expect.

2. Disease

Common culprits include root rot, leaf spot and canker; all caused by fungal infections. Telltale signs include black spots on leaves, mushy stems or bark lesions. Prune any affected growth with sterilised tools and ensure your plant has good air circulation. Avoid overwatering and remove any fallen leaves from the base.

3. Pests

Watch for pests such as scale insects, aphids and spider mites. These can sap your bay tree’s energy, leading to leaf drop or distortion. Check the undersides of leaves regularly. Natural solutions like neem oil or insecticidal soap sprays can help – just avoid harsh chemicals that may harm other plants or pollinators.

4. Pot size and pot drainage

If your bay tree is container-grown, pot size matters. A pot that’s too small restricts root development, while one that’s too large may hold too much moisture. Make sure your pot has adequate drainage holes and repot every few years to refresh the soil and allow for growth.

5. Lack of sunlight

Bay trees thrive in full sun to partial shade. If your tree is in a gloomy or shaded spot, especially in winter, it may become weak and leggy. Relocate it to a brighter position, ideally one that gets several hours of sunlight a day, especially during the growing season.

A struggling bay tree doesn’t mean it’s beyond saving. With a little observation and care, most bay trees bounce back beautifully. Whether it’s a gift you’ve received or a long-standing member of your garden family, a healthy bay tree is a joy to grow and can last for decades with the right attention.
