Now that I have such limited gardening space, I am reluctant to buy packages of seeds. I don't have the space to plant every seed, and while I can save them, I have to store them somehow where they won't go bad. And seeds are one of those things that are getting more expensive.
Another solution is to grow things from food I buy at the grocery store. Many vegetables and fruits can be started from cuttings and seeds from food that I eat. I can plant a few at a time as I collect more bottles and buckets to grow more. I've listed here some of the vegetables and fruits I have tried growing and some I haven't tried but will soon.
