I have The Backyard Homestead and I can’t recommend it enough. It’s been my top book for planning out my Garden these last couple of years and I’d probably be lost without it. If you’re seriously interested in this kind of stuff, I would also recommend 5 Acres and Independence, too… Even if you don’t have 5 acres to spare, I found the information invaluable, and the information in it is definitely adaptable to whatever sized plot you can spare.
Getting more specifically into the Gardening and Farming aspects, I have a few more suggestions for reading material:
Pirating Plants is about Propagation, grafting, and Seed Saving; it’s old but it’s solid and I definitely recommend it if you want to Garden on the cheap- especially when it comes to “larger than average” farming.
The New Complete Guide to Gardening by Better Homes and Gardens. Despite focusing mostly on your typical garden flowers, it does have some great information in it about a few Herbs and Fruit varieties, and all around has a lot of valuable information in it.
The Complete Illustrated Book of Herbs by Reader’s Digest, as well- though this one is obviously about Herbs specifically. But it covers basic remedies, culinary uses, planting, harvesting and storing, and a lot of other information.
