Sesame
Sesamum indicum
Zones 9–13
Growing
As a "survivor crop," sesame is remarkably resilient to heat and can thrive even when rains fail or soil moisture is low. To achieve the highest yields, focus on preparing fertile, well-drained soil with a neutral pH, as the plant is particularly sensitive to waterlogged conditions and high salt levels. Once you sow your seeds, ensure they are placed in a location that stays warm, as temperatures above 23 °C (73 °F) are ideal for vigorous growth.
Because the seeds are contained in capsules that naturally burst as they mature, harvesting requires a specific technique. Rather than waiting for the seeds to fall, cut the plants by hand when they are ready. Bundle the stalks together and stand them upright in a dry spot to allow the remaining capsules to open through a process called dehiscence.
Once the seeds are fully ripe and collected, keep them unwashed to prevent moisture from causing spoilage. You can store your harvest at room temperature or in a cool, dark cellar. For long-term preservation, drying the seeds is also an effective method.
