If you have a lot of planting to do, or can’t afford the price of the potting soil mix at the garden supply store, you can make your own. Here is a simple potting soil mix recipe for container gardening. It is rich in nutrients, which results in a thriving container garden!
8 parts potting soil, with vermiculite or perlite added
1 part coarse sand (usually less expensive at building supply stores)
4 parts peat moss, compost, rotted manure (one or all)
Combine in portions in the amount you need for gardening, mix well, and start planting!
