what does peat moss do
Peat moss is a highly absorbent, organic soil amendment that has many garden and plant care uses. It is taken from the bottom of sphagnum peat moss bogs where partially decomposed sphagnum moss accumulates. Peat moss itself does not contain many nutrients, but it absorbs and holds nutrients and moisture.ontainer Gardening. Add peat moss to the soil of your indoor and outdoor potted plants. If you mix your own soil, add about one third of the total volume in peat moss and mix well. You can also add peat moss on top of an already potted plant and gently mix it in.
