Answer: Concentrate on growing heat-loving vegetables, such as eggplant, summer squash, cukes, corn, tomatoes, beans, peppers, melons, pumpkins & winter squash. Native Americans in the High Desert of the Southwest devised a moisture-conserving planting method that works well even today. Sink your garden beds a few inches into the ground, and build soil berms around the planting beds. Your beds will catch rare rainwater, make best use of your irrigation, and berms create a barrier to protect seedlings from drying winds. Mulch plants with a thick layer of straw, old hay, or other organic matter - this keeps soil cool and maintains moisture. Deep rich soil (at least 12") encourages deep rooting and more drought-resistant plants. Grow varieties labeled "drought- and heat-resistant", such as Burpee's 'Heat Wave II' tomato. I also recommend a book, "Pat Welsh's Southern California Gardening: A Month-by-Month Guide" (Chronicle Books, San Francisco; ISBN# 0-87701-629-1). Hope this helps you grow a successful summer garden!
