I can’t speak for your own place and conditions, but much of my food growing area has only 6 inches of soil. So I’d say that it all depends upon your climate conditions and your gardening methods. I grow almost all of our own food plus excess to trade, sell, and giveaway. For long rooted crops like carrots and daikon, I use container boxes.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
