Planting a Retaining Wall

Rebecca's Garden : Episode REB-730 -- More Projects »
If you want to give your retaining wall a facelift, here's a solution. Give it character by filling cracks and crevices with cascading plants. To do this, create a peat paste—or, loose, muddy soil that will help the roots slide in easily.

Materials:
peat moss
potting soil
water
plants that adapt well to rock gardens

Steps:

  1. Mix the peat moss, potting soil and water together to create peat paste. Wrap the paste around the root ball ofa plant. Tip: Choose plants with smaller leaves because they look best cascading down a wall. Also, don't busy up the planting by using too many different varieties of plants.

  2. Slide the paste-wrapped root ball into a crack in the wall. You may have to push it in with a stick. Try to get rid of the air spaces. Tip: If you add globs of soil when you're building the wall, you'll have an easier time planting.

  3. Keep plants watered and fertilize every couple weeks.

In no time, your updated rock wall will look terrific.
