Cupressocyparis Leylandii 'Castlewellan Gold'

• Hybrid cross between Monterey Cypress and Nootka Cypress, developed in Wales and introduced to Australia in the mid-20th century.
• Fast-growing evergreen conifer reaching 15-25 metres tall with a narrow, columnar growth habit perfect for screening applications.
• Features soft, scale-like blue-green foliage that maintains colour year-round and produces small, round cones on mature trees.
• Popular choice for privacy hedging, windbreaks, and specimen planting due to rapid establishment and low maintenance requirements.
• Adaptable to various soil types and climatic conditions across most Australian growing regions except tropical areas.

• Water deeply 1-2 times per week during first year, then reduce to monthly deep watering once established in most Australian climates.
• Position in full sun for best growth and foliage density, though tolerates partial shade in hotter inland regions.
• Plant in well-draining soil with pH 6.0-7.5, adding compost to heavy clay soils to improve drainage and root development.
• Feed with slow-release fertiliser in early spring and mid-summer, using balanced NPK formula designed for evergreen trees.
• Trim lightly in late winter to maintain desired height and shape, avoiding cutting into old wood which doesn't regenerate well.
• Requires minimal humidity management but benefits from morning watering during extended dry periods in summer.

• Plant in full sun to partial shade with at least 6 hours of direct sunlight for optimal growth and dense foliage development.
• Water deeply once or twice weekly during establishment, then reduce to drought-tolerant watering schedule. Avoid frequent shallow watering.
• Tolerates temperatures from -10°C to 35°C and adapts to various humidity levels across Australian climate zones.
• Prune lightly in late winter to maintain shape and encourage dense growth. Avoid heavy pruning as it recovers slowly from hard cuts.
• Mulch around base to retain moisture and suppress weeds, keeping mulch away from trunk to prevent collar rot.

• Aphids can cluster on new growth causing yellowing foliage - treat with horticultural oil or insecticidal soap. Check regularly during spring growth periods.
• Canker disease may cause browning branches in humid conditions - ensure good air circulation and avoid overhead watering. Remove affected branches immediately.
• Root rot occurs in waterlogged soils causing yellowing and branch dieback. Improve drainage and reduce watering frequency in heavy clay soils.
• Spider mites can cause stippled, bronzed foliage during hot, dry periods. Increase humidity around plant and use miticide if severe.
