Plant seed in well-spaced mounds or in rows 2 to 4 feet apart, as you would plant cucumber or squash. Time the planting in late spring, when there is no danger of frost.
Cover the seeds with a half-inch of soil and keep watered until germination. Annual devil's claw grows thrives in rich loam soil with regular soaking.
Harvest the pods, which are edible raw or cooked as with okra: boiled, stewed, fried or pickled. The green pods grow to between 4 and 6 inches long.
Remove the seeds from dried pods and dry them. Store the seeds in a cool, dry place and plant next year.
