Some Fact about What is Peat Moss

Sphagnum Peat Moss

Sphagnum peat moss is composed of accumulated dark brown fibrous biomatter. It comes from a wetland. They are the remains of the dead materials of wild mosses that have been piled up in a peat bog over a thousand years.

Peat moss is from the genus Sphagnum. So what differentiates peat moss from the regular compost matter is the moss which it is made up of.

The process of decomposition in peat moss is very slow and it occurs anaerobically (without air). However, unlike most organic matter, peat moss is not a renewable resource since the decomposition process is very slow.

What is Peat Moss Used for?

Now that you have an idea of what peat moss is, we can now look into what they are used for. Peat moss is majorly used for soil amendments and soil components. Here are some of the uses or benefits of peat moss:

  • Water and nutrient retention: peat moss has the ability to hold water well. Therefore, you can use it for loose soil such as sandy soil which will help its water-holding ability. Peat mosses can also help sandy soil retain nutrients thus, reducing leaching.
  • Helps with soil compaction: also, when mixed with clay soil, it can help clay soil reduce its compaction. It will lighten or soften the consistency of the soil thereby making air and water to pass through easily.
  • Acidic pH: peat moss is great for acid-loving plants. e.g. camellias and blueberries.

  • Medium for planting: peat moss serves as a good transplanting medium for planting seedlings, or growing in containers. It is used as a constituent, mixed with other components that make up a fraction of the mixed volume.
  • Sterile medium for vulnerable plants: peat moss is free of microorganisms such as bacteria or fungi. They are also free from weed seeds. Therefore, it is a healthy and good choice for seedlings or plants that are just starting up.
  • Lawn improvement: another use for peat moss is as a soil mix for your lawn. Just like growing containers or trees transplanted, peat moss will help in water regulation, aeration, and nutrient holding capacity. It basically promotes the growth of healthy grass for your lawn.

How To Use Peat Moss In Vegetable Garden

To enjoy the benefits of peat moss in your garden, mix it evenly into the soil about 12 inches deep. Consider adding compost to the soil along with the peat moss to add the nutrients the plant needs.

If what you are looking for is to use peat moss as a soil amendment, mix 2 parts of soil and one part of peat moss.
