Plant Blue Rug Juniper in well-drained soil with full sun exposure. Space plants 4-6 feet apart to allow for spreading. Water regularly during the first growing season to establish a deep, extensive root system. Once established, water occasionally; junipers are drought-tolerant. Fertilize in early spring with a balanced, slow-release fertilizer. Prune lightly to maintain shape and remove dead or damaged branches. Avoid overwatering and ensure good air circulation to prevent disease.
