Suggestions for attacking a nearly verticle slope
« on: June 09, 2008, 05:32:10 AM »
I've got a friend who wants to garden on a nearly vertical slope adjoining a parking lot.  She's afraid to weed the slope because of erosion.  Anybody got suggestions for plants that would like this kind of terrain?  It's probably clay soil, by the way.

Tricky one..Patrick Blanc claims there are lots of plants that grow (originally) on near-vertical surfaces; most in between rocks though, or on trees.

Climbing vines established at the base of the surface, or in holes made in the soil, seems an obvious solution, but basically, woody shrubs like calluna should do fine as well.
