Potting mix, often referred to as potting soil (soil mix), is a specialized mixture prepared for container gardening. It is prepared by gardening experts to provide an ideal environment for potted plants. Unlike garden soil, which is found naturally in your outdoor space, potting mix is a man-made soil-mixture customize to the specific needs of potted plants. 

2. Key ingredients

A big difference between potting mix and garden soil is how well they let water and air move around.

  • Potting mix is made to let water drain well and give plant roots plenty of air. This helps roots grow strong and avoids them sitting in water.
  • Garden soil might not let water drain as well, so it is not the best choice for potted plants.

4. Nutrient levels
