Container gardens have been used for eons. Anything that has good drainage and enough sun can be used as a planter. “I can’t garden. It’s too hard.” is an excuse I hear at least once a year. In extreme cases, I have demonstrated that even two bags of potting soil can be a garden. I place the bags on their sides, making a level surface. I poke holes in the bottom side of the bags for drainage. I slice open the tops, and plant seeds or transplant plants. Poof. You have a garden. I do admit it’s an object lesson, but hey, it works. And yes, you can grow right in the bag. Container gardening does not have to be expensive. I’ve seen number 10 cans screwed to a fence line and bushels of produce ensue.
