How to Grow Sphagnum Peat Moss


Sphagnum peat moss grows naturally on top of bogs and swamps in many warm locations around the world. Sphagnum peat moss is used as a neutral growing medium for many plants and seeds. If you have access to cuttings from fresh, flourishing sphagnum peat moss, then its possible to grow your own in your home or back yard.

Step 1

Fill a basin with peat moss. If possible, use 12 to 20 inches of peat. Dampen the peat with distilled or rain water. Do not use tap water, as the chemicals present in household water could kill your sphagnum moss before it has a chance to start growing.

Step 2

Cut off the tips of healthy, growing sphagnum peat moss. Cut no more than 4 inches off the end of several branches and then cut the 4-inch pieces into 1-inch pieces. Keep the pieces damp by spraying them with distilled water.

Step 3

Distribute the 1-inch sphagnum cuttings evenly over the peat moss in your basin. Dust your cuttings with ground-up peat moss or with a light layer of mulch. Keep in mind that light must be able to reach your cuttings for them to grow properly.

Step 4

Spray your cuttings with distilled water from a spray bottle. Do not worry about over saturating your cuttings--it is vital that you keep them damp.

Step 5

Stretch a sheet of clear plastic over your basin to hold in warmth and humidity, mimicking the conditions in a swamp or bog.

Step 6

Place the basin in a sunny and warm location, out of direct sunlight. The temperature should never dip below 50 degrees F and should never exceed 70 degrees F. Once your sphagnum begins growing, remove the plastic cover sheet, but do not place the basin in direct sun. Keep your sphagnum damp at all times.
