Will Blue Rug junipers help stop erosion?

Juniperus horizontalis 'Wiltonii' - aka 'Blue Rug'

Q. We have a serious erosion problem on a slope beside our driveway. We like ‘Blue Rug’ junipers. Will they help stop erosion?

A. ‘Blue Rug’ junipers – aka Juniperus horizontalis ‘Wiltonii’ -  are fine for erosion control, but as with any ground cover, they hold soil best when they are mature. Since you have a “serious erosion problem”, you’ll have to take some measures to hold the soil in place until the junipers grow. 

I suggest you spread an erosion control blanket over the area, and then plant the junipers through it.
Erosion control blankets are available in several biodegradable materials including, straw, jute and coconut fiber in natural colors. The materials are held together with unobtrusive netting.  Water is allowed to percolate into the soil beneath while holding it in place. The ground cover plants will mature eventually to hide the blanket. The materials will decompose.
