Once the major soil slippage problems have been resolved, you can plant the hillside with a deep-rooted ground cover, so as to help stabilize the soil even more. Other varieties like C. 'humifusa' and 'horizonalis' are also well adapted to hillside culture. It is not unusual for plants of 'lowfast' to grow up to six feet in diameter. So it is generally recommended that gallon container size plants be planted on four to five feet centers. A native to the northwest, it is low spreading with evergreen leaves, which take-on a reddish tinge during the winter.
Spring flowers are white to pink, followed by reddish berries.
These plants tend to grow downward, so when they are used to retain soils, spacing of gallon container sized plants are usually staggered on about three or four feet centers. Probably the most popular one is Juniper 'Tam'. But, be sure to take a look at some of the others, like 'Bar Harbor', 'Wiltonii', 'Sargentii' and several others, because they seem less prone to disease problems. It is generally recommended that most of them be planted on about two to three feet centers for soil erosion. Planted this closely gallon container grown plants should fill-in in about two or three years.
