Missouri-based gardener Rebecca Nickols creates living-roof birdhouses for her business in Springfield. Follow her steps to design the perfect nest for the a backyard bird.
Step 1: Gather materials
Before you start on your bird haven, you'll need:
Moisture barrier (roofing paper or plastic)
Pole or pipe for mounting
Stapler, scissors, screwdriver
Step 2: Create a barrier
Cut the moisture barrier to fit the roof; set it in place.
Step 3: Top coat
Cover most of the roof with moistened potting soil.
Step 4: Moisten and pack
Soak sphagnum moss in water for 30 minutes to moisten it thoroughly. Wring it out with your hands, and then pack it thickly onto the soil in the roof.
Step 5: Staple
Staple poultry wire on top to hold the sphagnum moss in place.
Step 6: Trim
Trim the poultry wire back to the edges of the roof.
Step 7: Bring on the moss
With a screwdriver or an asparagus-cutting tool, poke even more sphagnum moss through the mesh in the poultry wire to fill any gaps or thin spots. You should not be able to see the potting soil underneath.
Step 8: Sow sedums
Plant sedums. Poke the asparagus-cutting tool into the moss to make room for the sedum roots and tuck the plants in, firming them with your fingers as you go. Rebecca uses hardy sedums in her living-roof birdhouses.
Step 9: Knob needs
Attach the knob with a screw on the side, so you can open the birdhouse to clean it out. The perch under the entry hole is optional. Birds don't need it.
