What is sphagnum Peat Moss or Peat Moss?

Before you begin working with peat moss, you should get a clear idea about the material itself to avoid making any mistakes during the procedure. So let’s begin-

Peat Moss, or sphagnum Peat Moss as some say, is actually just the dried, soil amendment version of decayed sphagnum moss and other organic materials. The peat moss we use in gardening at present is actually millions of years old decomposed sphagnum moss fibers harvested from the peat bogs.

Sphagnum moss is a common plant in peatland, and swamps situated in cold, northern hemisphere regions like Russia and Canada. As these dried fibers can hold about 30 times as much water as their dry weight, they can increase the soil’s water-retaining capacity. Therefore, they became popular among gardeners in the 1940s.

Why Choose Biodegradable Peat Moss Planters or Pots

Aside from being used in increasing the soil’s water-holding capacity, another popular usage of peat moss is producing biodegradable peat pots for seedlings. At present, biodegradable seed starter pots have become extremely popular amongst gardeners as an eco-friendly alternative to plastic seed trays.

But aside from this reason, gardeners also prefer using them to propagate plants that love being pot bound. Thus they needn’t change pots when planting the plants in larger pots. It also saves their time and helps the plants’ health.

Furthermore, using peat moss in producing Biodegradable Peat Moss Planters and Pots can offer a gardener a pot capable of helping the soil keep moisture and nutrients. This becomes extremely helpful while planting seedlings that prefer sandy soil. Also, as the pot itself is made of peat moss, the gardeners can opt for adding a lesser amount of peat moss while preparing the potting mixture and save the cost.

And lastly, peat moss is an alkaloid in nature. Therefore, using peat moss pots can give the seedlings of the plants preferring alkaloid soil an extra boost in their growth and health.

Peat Moss Planters Vs Pots

Above, we have learned quite a lot about biodegradable peat pots for starting seeds. But what exactly are peat pots?

In simpler terms, peat pots are made by compressing a mixture of peat moss, perlite, and shredded wood fiber pulp. You won’t find these materials being used in making regular pots. Check out the comparison table below if you want to learn more-

  • First, mix a 1:1:1 ratio of peat moss, perlite, and wood fiber pulp together to make a mixture of 1lbs amount.
  • Then add a bit of water and let it sit for the peat to absorb.
  • In the meanwhile, take an empty juice container and cut it at the desired height from the bottom to make an open-end box
  • Place the tube in an upside-down position to face it’s closed-end upwards, and create a 0.50-inch hole in the center using the drill.
  • Now take one of the wooden dowels and make a hole of 125-inch diameter, and 0.50-inch depth on its top center.
  • Now center the tube’s lid on top of the dowel and use a screwdriver to insert a screw through the lid to securely attach it to the dowel.
  • Afterward, put the container facing its open end upwards.
  • Then check the mixture and use your hands to slowly mix and knead it.
  • If necessary, keep adding water in small amounts until it gains a soft clay-like consistency.
  • Now insert about half a cup of the mixture into the open end of the tube.
  • Create air compression by inserting the lid into the top of the tube pressing the dowel on the lid. The dowel will help in magnifying the pressure and thus compact the mixture.
  • After the container’s shape is formed, remember to create a drainage hole inserting the other dowel through the pre-drilled hole.
  • Place the container near sunlight and allow the mixture to dry.
  • Lastly, gently turn the tube upside down to collect the peat pot.
  • Done!


You can also make large peat pots using this method. For that though, you’ll have to make sure that the mold used to have an appropriately sized lid to apply pressure. Also, you should put enough mixture into the mold so that the peat pot’s wall gains at least an inch thickness.
