Hi, We're the Hedge Cutting Staffordshire team, a professional gardener and hedge cutting contractor based in Staffordshire. These hedges are popular here in the Midlands due to their rapid growth and dense foliage, but they can present a few challenges. In this article, I'll share some common issues and practical solutions to keep your Leylandii looking its best.
Quick Answer
Leylandii hedges can grow too fast, become sparse, or suffer from disease. Regular trimming, proper spacing, and monitoring for pests can help maintain their health and appearance.
Common Leylandii Problems
Rapid Growth
Leylandii are known for their fast growth, sometimes up to 90 cm (around 3 feet) a year. While this is great for privacy, it can quickly get out of hand.
- Trim at least twice a year, ideally in spring and late summer.
- Keep them at a manageable height to prevent blocking light and views.
- Avoid cutting into old wood; Leylandii don’t regenerate from it.
Sparse Foliage
Another common issue is sparse foliage, which can occur if the hedge is not properly maintained or if it suffers from pests or diseases.
- Ensure the hedge is evenly trimmed to promote dense growth.
- Check for signs of pest infestation or fungal diseases and treat promptly.
- Maintain good soil health with fertilisation as needed.
Diseases and Pests
Leylandii can be susceptible to a range of diseases such as canker and root rot, as well as pests like aphids and spider mites.
- Inspect regularly for discolouration or unusual growth patterns.
- Apply appropriate fungicides or insecticides if necessary.
- Ensure good air circulation by not planting too close together.
Maintenance Schedule
To keep your Leylandii healthy, maintaining a regular schedule is key. Here's a simple guide you can follow:
| Month | Task | Notes |
|---|---|---|
| March | First trim | Before new growth starts |
| June | Check for pests | Inspect and treat as needed |
| August | Second trim | Shape and manage height |
| October | Final check | Prepare for winter |
Frequently Asked Questions
How tall can Leylandii grow?
In ideal conditions, Leylandii can reach heights of up to 20 metres (around 66 feet) if left untrimmed. Regular trimming is essential to keep them manageable.
Can I plant Leylandii close to my house?
It's best to plant Leylandii at least 3 metres (10 feet) away from buildings to avoid potential root damage and ensure good air circulation.
What should I do if my Leylandii turns brown?
Browning can indicate disease or poor soil conditions. Check for pests, water stress, and ensure proper nutrition. Trim out dead parts to encourage new growth.
