Harvest Tips
Begin harvesting when plant has 6-8 true leaves by pinching off the top 2-3 leaf pairs just above a node. Harvest regularly (every 1-2 weeks) to maintain bushiness and delay flowering. Morning harvest after dew dries provides best flavor. Use fresh or dry by hanging bundles in a warm, dark location for 1-2 weeks.
