An old favorite for
covering slopes and steep banks are spreading junipers. These
types of Junipers
are known for their fast growth, adaptation to poor soil, and low maintenance requirements. These evergreen plants are usually spaced
three to four feet apart, with every other row being staggered for
even cover. Closer spacing requires more plants but
provides faster cover of a planting area.
Weed control is extremely important during the first
few years, while the junipers are filling-in and covering the slope.
Eventually, the plants will completely cover the planting area,
reducing the requirements for annual mulching and weed control.
