    Apr 19, 2022 · A soilless mix is also called potting soil or potting mix or organic soils. While it is technically a soil because you can grow plants in it, it is mostly organic matter without much (if any) minerals in it. That means it doesn't have much sand, silt or clay in it. Because it is mostly organic matter, it:
