Landscaping Uses

Plant your Blue Rug Juniper on slopes and hillsides where it will cascade gracefully down ledges and prevent soil erosion.

Planting & Care

Choose a location with full sun to partial sun and ensure the soil drains well. Plant in early spring or fall, amending alkaline soils with acidic fertilizer if needed. Apply 2 to 3 inches of mulch around the base to retain moisture and protect lower branches. Water regularly during the first few months until established, then water only during dry periods. Fertilize at planting time and again each early spring with slow-release evergreen fertilizer. Once mature, light pruning improves air circulation and maintains the desired shape.
