These fast-growing conifers are popular for creating privacy screens and windbreaks in gardens, particularly here in the Midlands. In this guide, I'll share practical advice on planting, growing, and maintaining a Leylandii hedge.
Quick Answer
Leylandii hedges should be planted 60-90 cm apart in well-drained soil, preferably between October and April. Regular trimming is essential to maintain shape and prevent overgrowth.
Choosing the Right Location
Before planting, it's crucial to choose the right location for your Leylandii hedge. These trees thrive in full sun but can tolerate partial shade. Ensure the soil is well-drained, as Leylandii do not favour waterlogged conditions.
Planting Your Leylandii Hedge
When to Plant
The best time to plant Leylandii is between October and April when the ground is moist but not frozen. This allows the roots to establish before the summer heat.
Planting Process
Start by digging a trench about 45 cm deep and wide enough to accommodate the root ball. Space each plant 60-90 cm apart depending on your desired density. Backfill with a mix of soil and compost to promote healthy growth.
Caring for Your Hedge
Watering and Feeding
Water newly planted Leylandii regularly, especially during dry spells. Once established, they require less frequent watering. A balanced fertiliser in spring can encourage lush growth.
Pruning and Trimming
Regular pruning is key to keeping Leylandii hedges neat and manageable. Trim your hedge at least twice a year, ideally in late spring and early autumn. Avoid cutting into old wood as Leylandii do not regenerate from old wood.
- Plant in well-drained soil
- Space plants 60-90 cm apart
- Trim twice a year for best results
Common Issues and Solutions
Leylandii can suffer from browning and dieback if not properly maintained. Regular trimming and ensuring good air circulation can help prevent these issues. If you notice signs of disease, remove affected branches promptly.
Climate Considerations
In the UK, Leylandii are hardy and can withstand cold winters typical of the Midlands. However, they should be protected from strong winds when young to prevent root disturbance.

Frequently Asked Questions
How fast do Leylandii grow?
Leylandii can grow up to 90 cm a year under optimal conditions, making them one of the fastest growing hedges.
Can Leylandii be grown in pots?
While possible, growing Leylandii in pots is challenging due to their size and growth rate. They require large pots and frequent repotting.
What should I do if my Leylandii turns brown?
Browning can result from poor drainage, pests, or disease. Ensure proper watering and prune affected areas to improve air circulation.
