A Peaceful Streambed

Gardening by the Yard : Episode GBY-810 -- More Projects » (Continued from Page 1)

If you have a rocky soil, you'll need something, such as sand or newspaper, to insulate the liner so it won't tear. Lay the newspaper or sand along the bottom and then lay durable, 45-mm rubber liner in the streambed, making sure it overlaps the lip by at least one foot. Using a tape measurer and scissors, trim the liner to one foot out from the edge of the stream and get rid of the excess lining (figure D). You can make your own homemade landscape fabric staples by bending wire into an inverted u-shape (figure E) to secure the liner to the ground.

Figure F

For the water starting point, consider a special feature like this stone monolith with bamboo spout (figure F). PVC pipe is a great material for this project because it's easy to cut and has all kinds of connectors to fit the bends of the streambed (figure G). Use quick-drying PVC pipe adhesive to bond the pipes and the water pump together for a watertight seal.

Add a drainpipe so the bed can be emptied periodically (figure H). The pipes that stick up are where the water flows up over the rocks, and the nearby valve can adjust the speed of the water from these pipes.

Day Two

On the second day, wash river rock thoroughly before adding it to the streambed so that it doesn't become a muddy mess. Layer the rocks over the pipes in the streambed to disguise the plumbing (figure I), using a rounded shovel to minimize the risk of puncturing the lining. Use large pieces of slate to form a ledge around the lip of the stream and smaller pieces to create a stair-step into the water (figure J).

Add plants along the outer perimeter to soften the stream's edge (figure K). Glassman chooses Japanese snowberry (figure L), serpentine cedar (figure M), nandina (figure N), sago palm (Cycas revolute) (figure O), Japanese maple (Acer palmatum). He fills in with interesting groundcover, including carpet roses, mondo grass and Ophiopogon (figure P). The effect is stunning: a natural, soothing sanctuary that will never be neglected again.
