Potting Mix

We are offering potting mix. Potting mixes made mostly from sand will have little ability to hold plant food, while mixes formed from lots of peat moss or compost will hold plant food well. The ph of the mix also affects nutrient availability. Peat moss, which is the most commonly used ingredient in potting mixes, is very acidic (low ph). Dolomitic limestone is often added to adjust the ph and bring it closer to neutral. Compost and sand are usually neutral (depending on what they are made from) and may require less limestone when they are used in potting mixes.
