Common Juniper is drought-tolerant once established, requiring minimal supplemental watering. Young plants, however, benefit from regular watering, especially during dry periods, to encourage root development.

Ensure the soil drains well to prevent root rot, as junipers do not tolerate consistently wet conditions. Reduce watering significantly in winter.

Pruning is generally minimal, primarily for shaping, removing dead or diseased branches, or controlling size. The best time to prune is in late winter or early spring before new growth begins.

Avoid cutting into old wood that lacks foliage, as junipers may not regenerate from these areas. Light annual trimming can maintain desired form.

Common Juniper can be propagated from semi-hardwood cuttings taken in late summer or early autumn.

Cuttings should be 10-15 cm long, treated with rooting hormone, and placed in a well-draining rooting medium under high humidity. Seed propagation is also possible but can be slow and erratic due to seed dormancy.

Repotting is typically not applicable as Common Juniper is usually grown in the ground. For container-grown specimens, repotting may be necessary every 2-3 years, or when the plant becomes root-bound.

Choose a pot only slightly larger and use a well-draining potting mix. Repot in early spring before active growth resumes.
