What is Sphagnum moss?

Sphagnum moss is commonly referred to as sphagnum moss and consists of a genus of about 380 species of moss. Live and dead Sphagnum moss can store large amounts of water. It is called a habitat manipulator because of its ability to alter the landscape wherever it grows. It can store up to 26 of its weight in water, so it can create a marshy area in a dry landscape. Sphagnum moss can grow 0.75 to 4.75 inches per year.

Grow Sphagnum moss - tips for growing and using indoors,and outdoors.


Many people prefer to grow spgahnum moss in the garden. Follow these steps:

  • Choose a location that has plenty of water. The moss can grow anywhere under the right conditions, but it does best in a bog-like environment.
  • Cut your live moss into pieces about 2.5 inches in size.
  • Plant the moss at a ratio of 1 to 10, using one piece for ten square feet.
  • Mulch lightly to retain moisture , but not so deeply that light cannot reach the moss.
  • Water regularly with rain or spring water. When the tops of the moss look brown, it’s time to water.

Other tips for growing your own moss culture:

There are numerous ways to use the harvest of sphagnum moss

  • Give your moss high humidity. Live moss cultures grow well on sunny windowsills in a covered plastic food container – add some ventilation holes to the lid or sides.
  • Use a container with drainage holes and add a layer of large-sized perlite, Leca clay, or washed gravel as drainage on the bottom.
  • Use distilled water or reverse osmosis water and spray your new culture every few days – extremely clean water is key.
  • Sphagnum moss is slow growing. Be patient. Under optimal conditions, the moss will grow into longer strands over time. To propagate, cut off the heads of the longer strands and replant them in the same container in a different location. After a few months, they will be large enough to cut off and repeat the process.

How you can use the moss?

Leave the fibers long and use them as a base for your hanging baskets


There are numerous ways to use the harvest of Sphagnum moss in indoor and outdoor gardens.

Dried Sphagnum moss

The classic method is to thoroughly dry Sphagnum moss. Lay out your Sphagnum pieces between paper towels and press them down to extract as much moisture as possible. Repeat the process with fresh towels until no more water is extracted. Lay the cuttings out evenly on a flat surface in a well-ventilated area.

Allow the moss to dry for several days. Once it is completely dry, put it in a sealed container. You can leave it long-fibered or tear it into smaller pieces. Dried sphagnum moss is a perfect substitute for peat. You can use it whenever you want to improve drainage and water retention. Mix compost, perlite and sphagnum moss in equal parts to make the best potting soil.

Dried sphagnum moss is light and airy and makes an excellent soilless substrate

Soilless media

Dried peat moss is light and airy and makes an excellent soilless substrate for orchids , bromeliads, succulents and carnivorous plants.

Insert for hanging basket

Leave the fibers long and use them as a base for your wire hanging baskets. Start at the bottom and work up the sides until they are at least three inches thick.

Topdressing for container gardens

Sphagnum moss is perfect as a groundcover for houseplants and other garden containers – and it retains moisture, too.

Growing seeds

Fill your growing pots and seed trays with finely chopped sphagnum moss

Fill your growing pots and seed trays with finely shredded sphagnum moss. Then moisten it and sow your seeds. Sphagnum moss is a fantastic starting medium for seeds because not only does it retain moisture and provide drainage , but it is also airy, low in nutrients and has a neutral pH.

Protect bulbs

Keep stored bulbs dry and prevent rot by storing them next to dried Sphagnum moss. The moss will also prevent the bulbs from being damaged during shipping.

Living mulch

Another great way to use sphagnum moss is to keep it alive after harvest and use it as a living mulch for your moisture-loving plants. Orchids, ferns, sundews, pitcher plants, Venus flytraps and other plants with high moisture needs will benefit from a living layer of sphagnum in the pot.
