Light
Full sun outdoors, minimum 4–6 hours direct light daily. Never keep indoors permanently — junipers die slowly without UV and airflow. In summer, light afternoon shade prevents scorching.
Watering
Water thoroughly when the top 1cm of soil begins to dry. Allow the soil to approach dryness between waterings — junipers hate sitting wet. In summer, this may mean daily watering. In winter, reduce dramatically.
Temperature
Hardy to −15°C. Needs a proper winter dormancy period. Protect from frost below −10°C in a cold greenhouse or unheated shed — never bring fully indoors. Frost hardens the wood and is essential.
Pruning
Pinch back new growth throughout the growing season (spring–autumn). Never cut into bare wood — junipers do not back-bud from leafless branches. Remove all upward-pointing shoots to maintain the cascade or spreading form.
Repotting
Every 2–3 years in early spring before buds break. Use a free-draining mix (60% akadama, 40% pumice). Avoid root disturbance in summer or autumn.
Feeding
Balanced fertiliser (NPK 6-6-6) every 2–3 weeks from spring through mid-autumn. Switch to low-nitrogen (0-10-10) in late summer to harden growth before winter.
Spider mites in hot dry conditions — look for bronzing foliage. Scale insects on older bark. Root rot if overwatered in winter.
