With spring upon us and the warming of the earth, many readers are getting the urge and itch to get outside and start planting a garden. Whether your garden is large enough to feed a community or just big enough to supplement your everyday fresh greens addiction, at some point you will need a supply of potting soil. From container herb gardens to the square-foot garden method, potting soil will need to be on hand. High-quality potting soil is an essential component to a successful garden season because it provides the foundational medium in which your plants will start and continue to grow in. In this article I discuss the process and recipe that I have used for many years for making great potting soil.  I hope to provide you with ideas on how to make the best mix for your garden and ways to save money in the future.

  • 3 parts Peat Moss
  • 1 part Compost (can be a combo of compost and worm castings if you have a worm bin available)
