The birds will also be grateful when Juniper berries appear in the fall, as they are the perfect snack for our winged friends.
Blue Rug Juniper Care
The Juniper Blue Rug plant is a low maintenance species known for its ability to thrive in desert climates. When planted in ideal conditions, this Juniper is extremely easy to care for. During colder seasons, the silver-blue evergreen leaves will acclimate to the fluctuating temperatures of snow and frost. A common pest that occurs in this evergreen shrub is spider mites. This can be prevented by hosing the plant with a strong spray of water and will disrupt web-making.
How To Plant Blue Rug Juniper Ground Cover

Plant Blue Rug Juniper ground cover in a hole double the size of the root ball. This trailing juniper is drought tolerant and prefers less moisture in its root systems. Juniper shrubs are also tolerant to salty or sandy soils and can be planted near the coast.
How Big Does Blue Rug Juniper Grow
The Blue Rug Juniper will spread about 6-8 feet and only reach .5 feet in height. Plant this shrub staggered, 3 to 4 feet apart to ensure full coverage groundcover functions.
How To Prune Blue Rug Juniper
Pruning a Blue Rug Juniper should be done lightly to achieve the desired shape. Heavy trimming is not recommended because Junipers usually have dead zones in their center. This means that some areas on a mature Blue Rug plant may not receive sufficient light and will dry up. On most occasions, new growth will not develop in this area unless there are remaining green needles on the affected branches.
Creeping Junipers, like the Blue Rug, should be pruned by cutting back to make strong lateral branches. Prune your plant by following its natural growth patterns, and cut above the dead zone. As always, make sure your shears are sanitized to reduce cross-contamination and prevent disease.
Is Blue Rug Juniper Deer Resistant?
The Blue Rug Juniper is deer resistant unless it is the only specimen in the area. Juniper plants are not deer’s first choice but will be more attractive when they produce berries.
Blue Rug Juniper Landscaping Ideas
Blue Rug Junipers make a great addition to all sorts of landscapes. If you’ve ever wanted a green wall, look no further! You can train the Juniper to cascade over walls to encourage a centered growth habit. They are most commonly seen in rock gardens, retaining walls, and borders as their creeping habits given the landscape a multi-dimensional look. If you have bare sandy soil spots in your yard, the Blue Rug Juniper will surprise you with its ability to thrive in dry conditions. Keep in mind that this Juniper variety does best in well-draining soil to avoid root rot. The evergreen foliage will develop a purple shade in winter, giving a great contrast to whatever landscape they are planted in.
