Blue rug juniper is a form of Juniperus horizontalis. It is a popular shrub that serves well as ground cover. Blue rug juniper has a blue-silver color most of the year but turns to a mauve-colored tint in the winter. The blue rug juniper is typically dense and grows fairly fast in a low-growing fashion. It can spread an average of about 6 feet in 10 years. In addition to being a good ground cover for large areas, blue rug juniper can be planted on banks for erosion control.
Plant blue rug juniper in USDA hardiness zones 3 to 9. Choose a planting location that has well-drained soil. The dirt doesn't have to be high in nutrients. The plant does fine in mostly sand to mostly clay soils.
Make sure there is some light in the planting spot. Blue rug juniper needs some sun to full sun in order to grow.
Dig a hole that is twice as wide as the shrub's root ball. Use the nursery container as a guide to determine exact size. Make the hole as deep as the plant is in the container. It needs to be planted at the same level, not beneath the surrounding ground.
Pull the blue rug juniper out of the container gently. Use your hands to separate the roots.
Position the plant in the center of the hole. Fill in around the roots with the removed soil. Press down on the soil to remove air pockets. Water it well.
Check the water content of the soil every couple of days for the first few weeks. Make sure it is moist to the touch, but not wet. As the plant matures, it will be better able to tolerate drought.
Lay mulch around the base of the plant. Pile on 2 to 3 inches. This will help the soil retain moisture and cut down on weed invasion.
