How to Care for Blue Junipers

Overview

Juniper is a genus of hardy, evergreen shrubs with several species and cultivars that sport blue-toned foliage. Blue foliage cultivars include Blue Mat, Angelica Blue and Blue Creeper. All species of juniper have nearly identical care requirements, which are minimal. Blue junipers can tolerate a wide range of soil and temperature conditions, require no fertilizer and prefer not to be pruned. They give color and texture with no hassle, making them an ideal landscape plant.

Step 1

Grow your blue juniper in USDA zones 5 through 9 in a location with full sun exposure. Provide deep, loamy or sandy soil that can hold some moisture but remains easy draining. Keep the soil pH 6 and 8.

Step 2

Water your blue juniper consistently and deeply to keep the soil evenly moist at all times. Established junipers can tolerate drought conditions but perform best in consistently moist soil. Allow the surface of the soil to dry slightly between waterings and be mindful not to keep the soil soaking wet as the roots can be smothered.

Step 3

Refrain from pruning your blue juniper substantially to alter the size, shape or branch form. They are very slow-growing and cannot regenerate their major limb architecture. Remove any small bits of dead foliage or discolored tips carefully and only when needed. Follow the natural form of the shrub for a professional and natural result.

Step 4

Mulch around the base of your junipers with a few inches of shredded bark or cocoa bean hulls to hold moisture in the soil, keep weeds down and prevent any lower foliage from coming into contact with the soil.
