Broad Leaved Nira reaches harvest readiness in 100-109 days from planting. Begin harvesting the tender young flower stems and unopened flower buds once the plant has established robust growth and the stems are long enough to handle. Cut the flowering stems at the base or pinch off the buds as they emerge; harvesting encourages continued production and prevents the flowers from opening fully, which extends the tender harvest window. The broad leaves themselves can also be harvested once the plant is established, though the flower stems are the primary target.
