Harvest Tips
Begin harvesting leaves 5-6 weeks after planting when they reach 4-6 inches long. Pinch off outer leaves regularly to encourage bushier growth and continuous production. Harvest in morning after dew dries for best flavor and texture. For seeds, allow flower spikes to fully mature and dry on plant, then cut and further dry indoors before threshing. Young leaves are more tender and have better flavor than mature leaves.
