For the newbie, you may have a little anxiety over your first garden and what vegetables will be grown. Farmscape has put together a wonderful guide for school gardens (summer crop catalog) they help design, but it can easily be applied to the home gardener. Their plan is for a 4' x 12' garden and insures a balanced harvest.
The plan includes beans, cucumbers, eggplants, herbs, melon, peppers, squashes and tomatoes.
Farmscape will help you build and maintain your home garden or school in the Los Angeles area if you aren't able to manage your own home garden.
