FAQs
How far apart should I plant these for a hedge?
We recommend planting 2 to 3 plants per metre for a dense, well-integrated hedge.
Can I plant these in partial shade?
Yes, Castlewellan Leylandii is versatile and performs well in both full sun and partial shade.
How tall do they get?
While they start at 30–40cm, they are naturally fast-growing and can reach significant heights if left unpruned, which is why regular maintenance is advised.
Do I need to fertilize them?
While not strictly required, a balanced slow-release fertilizer in early spring can help young plants establish more quickly.
When is the best time to plant them?
Spring or autumn are the ideal seasons to plant, as the cooler temperatures and moderate rainfall help roots establish without excessive heat stress.
Are these plants evergreen?
Yes, they are evergreen conifers that retain their golden-green foliage throughout the year.
Troubleshooting
Browning foliage near the base
This is often caused by lack of light or poor air circulation. Ensure the hedge is not planted too densely and trim the sides to allow light penetration.
Wilting shortly after planting
This indicates water stress. Increase the frequency of watering, particularly during the first few months after transplanting.
Uneven growth rates
Check soil quality in the lagging areas and ensure all plants are receiving adequate water and mulch.

Setup, Compatibility & Care
Preparation: Clear the planting area of weeds and enrich the soil with organic matter if the ground is particularly poor.
Planting: Dig a hole twice the width of the 9cm pot and place the plant so the top of the root ball is level with the soil surface.
Spacing: Space plants 33cm to 50cm apart (2-3 per metre) to ensure a dense, interlocking hedge wall.
Watering: Water heavily immediately after planting. During the first two growing seasons, ensure the root ball remains moist, especially during dry summer spells.
Maintenance: Begin light pruning once the plants have reached your desired height to encourage lateral growth and density.
