Here is what I am reading right now from the library:
1) All New Square Foot Gardening - by Mel Bartholomew - This is the updated version and is WAY better than the first version. Lots of colored pictures. Simplified information.
2) Lasagna Gardening for Small Spaces - by Patricia Lanza - I actually meant to get her regular lasanga gardinging book, but this one still has all the useful information. I will be trying a modified form of this in a few beds this year.
3) How to Build Your Own Greenhouse - by Roger Marshall - Brad has found this very helpful and informative. Good for helping you decide how you really want to use a greenhouse and what type you need. I am sure that I will be checking it out again in the future.
4) Chickens in Your Backyard, A Beginner's Guide - by Rick & Gail Luttmann - Good information, the most concise I have seen so far. It answered a lot of questions for us.
