Watering. Water regularly during the first growing season to establish roots. Once established, water deeply but infrequently, allowing soil to dry out between watering to prevent root rot.
Fertilizing. Fertilize once a year in early spring with a balanced, slow-release fertilizer to support healthy growth. Avoid over-fertilizing, which can cause excessive, weak growth.
Juniperus chinensis is a hardy evergreen shrub or small tree that prefers full sun and well-drained soil. It tolerates drought well once established but does not like overly wet or poorly drained conditions. Regular pruning helps maintain its shape and health, but it generally requires moderate care.

- Moderate
Juniperus chinensis can produce pollen that may cause mild allergic reactions in sensitive individuals, especially during its pollination season. People with pollen allergies should avoid close contact during this time. The plant's sap may also irritate the skin in some people, so wearing gloves when handling is recommended.
Common problems
Common problems include root rot if overwatered or planted in poorly draining soil, and occasional pest issues like spider mites or scale insects. Lack of sunlight can cause sparse growth.
Uses
Used mainly as an ornamental plant in gardens, parks, and bonsai. Also used for hedges and ground cover due to its dense foliage and hardiness.
Notes
Prune in late winter or early spring to shape and remove dead branches. Avoid heavy pruning into old wood as it may not regrow well. Repot bonsai forms every 2-3 years. Sensitive to overwatering and poor drainage.
