Live sphagnum moss can be used as a decorative element in many flowers and plants, including bonsai and orchids. In addition, many plants, including orchids, will grow very well in a base of live sphagnum moss. Growing sphagnum moss is not difficult. It requires temperatures between 50 and 70 degrees F and as such is best grown indoors in the winter.
Fill a large plastic tub or container 3/4 of the way with peat moss. Peat is a a good substrate for growing other mosses.
Add water to the peat moss substrate. The peat should be damp, but not dripping wet.
Take cuttings from the top 10 cm of actively growing sphagnum moss. Cuttings taken below this level have a higher failure rate.
Chop the cuttings into separate lengths that are 1 to 3 cm. Scatter these cuttings evenly over the peat moss. Cuttings taken from 1 square foot of live moss should be enough to start aabout 10 square feet of moss in containers.
Mist the top of the sphagnum moss regularly until it starts to grow. After it begins to grow, occasionally flood the moss with 1 to 3 cm of water.
Consider partially covering your container with clear plastic to retain humidity in the container in a very dry climate.
Keep the container out of direct sun. A good location for sphagnum moss is along one side of a room with a medium or large window where sun shining through the window won't hit the container.
