Good Question, Tot!
I'm like Janie, live in a city condo with a patio and although there's room for a "container garden" this year I only planted herbs and flowers.
I was raised in the country nearby though, and every year we grew and canned our own groceries, and even raised livestock & hunted, so we butchered our own meat to supplement our freezer, so I know the life-style well. In fact, I'm lucky as my Dad & his wife still keep a garden, so I work it often w/ him and benefit from his shared bounty.
For most of my adult life I've worked a hectic job that didn't leave much time or energy for gardening- even though for some it's a relaxing hobby- I recognize that gardening is hard work that requires daily attention. I also worked a job where I was at random locations for sporadic, brief periods of time that invlolved constant travel and long periods away from home, so planting and the upkeep of watering, weeding, harvesting, etc. just didn't fit into my lifestyle then.
Next summer I hope to plan and grow many things. I'm gonna take CanMan's advice and try growing the up-side-down 'maters. I also hope to follow Cathy's and Frannie's lead and grow so much that I have stuff to put-up for the winter, and share w/ neighbors!
