What is the best book you know?

Too, too, too many! Thousands, Millions? of gardening books! Call your county agent and see what he/she suggests. Every area is different and what works in one won't always work in another. In Texas, a lot of folks swear by Neil Sperry and up north, a lot of folks will go with Jerry Baker. I've read both and they are both good. Baker is a lot more fun to read as Sperry is more like a droning college professor.
