Rocky Mountain Juniper prefers well-drained soil and is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out between waterings.

Avoid overwatering, which can lead to root rot, especially in container plants. Monitor soil moisture during hot, dry periods.

Prune to maintain desired shape and size, or to remove dead, damaged, or crossing branches. The best time to prune is late winter or early spring before new growth emerges.

Avoid heavy pruning into old wood, as recovery can be slow. Light shaping can also be done in summer.

Propagation is typically done from semi-hardwood cuttings taken in late summer or early fall. Dip cuttings in rooting hormone and plant in a well-draining medium. Maintain high humidity and provide bottom heat.

Seed propagation is also possible but can be slow and may require stratification.

Container-grown Rocky Mountain Junipers benefit from repotting every 2-3 years. Choose a pot that is only slightly larger than the current one, with ample drainage holes. Use a well-draining potting mix.

Repot in early spring before new growth starts. Trim any circling roots to encourage outward growth.
