Question: what is the difference between planting mix and potting mix?
Answer: Potting soil is a mixture of bark, peat moss, vermiculite and compost; planting mix is a combination of garden loam and peat or bark. ... Potting soil is light, even when wet, and will drain quickly (and dry out faster). Planting mix is heavier, and while it drains well, will hold moisture for a longer period of time.
