Square Foot Gardening
Square Foot Gardening, by Mel Bartholomew (Rodale Press, 1981; $17), is a classic in gardening literature that's still as relevant today as it was 20 years ago.
The book's approach is deceptively simple and the advice straightforward and down-home practical, including charts of when to plant seeds and set out transplants according to the frost dates, as well as information on how to use succession planting to maximize the use of garden space and extend the season, how to improve your garden's soil, and how to grow vegetables.

It also highlights some of the factors to consider when selecting a tree for a specific spot in your yard.
