Sonoran Desert Beans, commonly identified as Tepary Beans, are adapted to hot and dry environments. Compared with many common garden beans, they can tolerate higher temperatures and lower water availability once established.
Yes. Tepary Beans are warm-season crops suited to hot growing conditions. Sow them in warm soil, provide full sunlight, and maintain adequate moisture while seedlings establish.
Allow the bean pods to mature and dry on the plants. Harvest the dry pods before they split open, then remove the beans and allow them to dry thoroughly. Store completely dry beans in an airtight container in a cool, dry location.
