The Q&A Archives: When To Plant Sweet Peas?

Question: I live in Southern Arizona and would like to know when to plant sweet peas.

Answer: Sweet peas are cool-season annuals in the low desert, best planted from October through February. There are two distinct growing seasons in the low desert with different annuals thriving in each season. There's a cool season from approximately the end of September through April. Annuals can be installed from late September to February. Some gardeners prefer to wait until October, as cooler temperatures also help kill off whitefly populations which can quickly decimate plants. The warm season starts with planting in mid to late February. Some plants will make it through the summer's heat; others will end their growth when the heat arrives. A good reference book that contains planting calendars for the low desert is called "Desert Gardening for Beginners: How to Grow Vegetables, Flowers and Herbs in an Arid Climate." ISBN 0-9651987-2-3. Good luck!
