One of the most common questions I’m asked is “how much money did it take to fill your beds? It must have cost a fortune!”. And they’re right, buying raised bed or potting soil mix from the store is very pricey! The Square Foot Gardening book introduced me to how to make my own and I’ve been doing that ever since. We have a blog post that details how we make our own soil.
Check out this video to see how I make our soil mix using peat moss, vermiculite, and compost. I buy the peat moss from a hardware store, the compost is made at home, and the vermiculite can be found any your local garden center in 4 cu/ft bags. I usually pay around $30 for a bag.
