DETAILS

Care Instructions
Rocky Mountain juniper thrives in direct bright light and prefers moderate temperatures. It can tolerate dry conditions but benefits from occasional watering during prolonged dry spells. The tree does well in low humidity environments and can withstand cold winters.
Soil
This juniper prefers well-draining loam soil but can tolerate a range of soil types, including sandy and rocky soils. It is important to ensure good drainage to prevent root rot.
Fertilizer
Rocky Mountain juniper generally does not require fertilization. If desired, a balanced, slow-release fertilizer can be applied in early spring.
Repotting
Repotting is generally not necessary for outdoor junipers. However, if grown in a container, repotting should be done every 2-3 years in early spring. Use a well-draining soil mix and ensure the new container has adequate drainage holes.
Propagation
Propagation can be done through seeds or cuttings. Seeds should be stratified before planting, while cuttings can be taken in late summer and rooted in a well-draining medium.
Pruning
Pruning is recommended to maintain the desired shape and remove any dead or diseased branches. Prune in late winter or early spring before new growth begins.
Toxicity
Juniperus scopulorum is not considered toxic to pets or humans. However, the berries can cause mild gastrointestinal upset if ingested in large quantities.
Additional
Rocky Mountain juniper is drought-tolerant once established and can be used for erosion control and as a windbreak. It is also valued for its aromatic wood, which is resistant to decay.
