Skyrocket juniper (Juniperus scopulorum 'Skyrocket') is a rigidly upright shrub that reaches heights of 15 feet at maturity. The attractive foliage is bluish-grey and may take on a bronze tint during the winter. The tall, narrow shrub is a good choice for a privacy screen and works well in narrow spots in the landscape, as the width of the shrub is limited to only 24 inches. Also known as Colorado redcedar or Rocky Mountain juniper, Skyrocket juniper is a cold-tolerant plant suitable for planting in U.S. Department of Agriculture hardiness zones 3 to 8.

Plant Skyrocket juniper in full sunlight as shade will result in sparse growth. Skyrocket juniper thrives in nearly any soil type, but doesn't tolerate high humidity, soggy soil or standing water. Allow 24 inches between each shrub to provide adequate air circulation.
Water Skyrocket juniper regularly and keep the soil moist, but not soggy, until the shrub is established. Thereafter, Skyrocket juniper is drought-tolerant and requires no supplemental irrigation.
Prune Skyrocket juniper, if needed, in late winter after danger of a hard freeze has passed. Remove any dead branches. Otherwise, trim only the tips of the branches to keep the shrub neat and shapely. Never prune into bare wood, as the shrub won't rejuvenate after a severe pruning.
Feed Skyrocket juniper in early spring, using a granular fertiliser formulated for evergreens. Apply the fertiliser according to the specifications on the fertiliser container.
