Potting soil is a weed-free, packaged soil mix that is formulated for maximum results for most plants. It is most commonly made from a mix of several ingredients including sterilized soil, peat moss, vermiculite, recycled mushroom compost, and perlite in varying proportions depending on its intended use and sold in bags weighing from 5 to 50 pounds (2.3 to 22.6 kilograms).
Potting soil may also be known as potting mix.
Potting soil is commercially available in several varieties or you can prepare your own blend. Choosing just the right potting soil mix requires knowing the optimal growing conditions for the specific plant.
For example, African violets prefer a moist, nutrient-rich potting soil mix that is heavy in peat moss, while the more arid climate cactus thrives in a mix heavy in sand and vermiculite for ample drainage.
