Vermiculite holds water and fertilizer in the potting mix. It also contains calcium and magnesium, and has a near-neutral pH. Vermiculite comes in different grades. Medium grade is usually used for starting seeds. A coarse grade can be used in soil mix for older plants.
Canadian Spaghnum Peat Moss
Peat moss is a very stable source of organic material that holds a great deal of water and air and does not decompose quickly. Peat moss is quite acidic (pH 3.5-4.0); limestone is added to the mix to balance the pH. Hyde Park, a Younger, lighter colored peat moss does a better job of providing air space than does older, darker peats that have few large pores for air space.
Perlite is a volcanic rock that has been heated and expanded to become a lightweight, white material. Perlite is sterile and pH-neutral. When added to a soil mix, perlite can improve air space and water drainage. It is a hard material that does not break apart easily. Perlite pieces create tiny air tunnels, that allow water and air to flow freely to the roots. Perlite will hold from 3 to 4 times its weight in water, yet will not become soggy. Perlite can be used instead of sand to reduce the soil mix weight.
