You can make gardening so affordable it’s better than free:

One story I forgot to mention in the video: we were totally broke one spring, so I went dumpster diving. In one grocery store dumpster I found buckets of potatoes – red, yellow and white. I took them home and dug a bed, threw them in there, covered ’em with straw, and we ended up harvesting buckets and buckets more!

Where there’s a will, there’s a way.
