Calgary Carpet Juniper

Rich green mounds of juniper beauty only grow ankle-high for the perfect mountain ground cover. An ideal choice for low water, low care erosion control on natural banks where monsoon run-off is a problem. The perfect green nestled between boulders or soften the top edge of a masonry retaining wall. Ideally used to add color and style next to a barren rock lawn through the winter months. Junipers are always naturally welcome in Japanese gardens or pruned into creative bonsai forms.

How to Grow Calgary Carpet Juniper

A superior evergreen groundcover with a very low, spreading habit and attractive soft green foliage. Use on slopes for groundcover or erosion control, along walkways, and in borders or rock gardens. Drapes nicely over retaining walls. A very durable landscape specimen that tolerates mountain heat, cold, and drought.


Full sun is preferred by juniper, although young plants will grow well in partial shade.


Juniper is a super hardy shrub that grow well in different types of soil. Loam is ideal, but sand or clay will also be sufficient for this tree to thrive. Juniper even tolerates salty mineral soils.


Water twice weekly, only once well established after the first year of growth. The water guide for this shrubs is deep soak as soon as planted and bi-weekly for the first year. A one-hour trickle that slowly saturates the root provides proper water for a new tree. Adjust watering based on rainfall.

Temperature and Humidity

Calgary Carpet Juniper can grow in a variety of climate conditions, but it will perish if exposed to temperatures below minus -30 degrees F.


Older shrubs rarely need additional irrigation. For young shrubs feed three times per year with 7-4-4 All Purpose Food (March, July, and October).


Juniper plants need little pruning except to remove dead or diseased branches. The best time to prune is in late winter (January through March), when sap flow is reduced by colder weather.
