The term for the mixture of fertilizers and soil used in gardening is called potting mix or potting soil. Potting mix is specially formulated to provide the right balance of drainage, aeration, and moisture retention, essential for the health of potted plants. It typically contains components such as peat moss, perlite, vermiculite, and sometimes compost or fertilizers. These ingredients help support root growth while providing nutrients for plants. Different plants often require specific potting mixes tailored to their needs, such as cacti and succulents, which prefer well-draining mixes, while tropical plants thrive in more moisture-retentive media.
