Fluffy texture - By featuring a lightweight, fluffy, and easy to penetrate texture, potting mixes provide the easiest and best-growing media for roots.
Aeration and drainage - Potting mixes additionally have a better air-flow and water drainage than potting soils, which usually and eventually, become compacted.
Water retention - The addition of peat moss, perlite, and vermiculite, provide excellent water drainage, retention, and airflow properties, which is ideal for most plants.
Right nutrient mix - With a potting mix, nutrients are available in the right combination, and unlike natural soil, there is no pH testing or amendments necessary.
