Harvest Tips
Harvest leaves anytime after plant is established (8-12 weeks old). Pinch or cut terminal leaves and stems just above leaf nodes for continuous harvesting and bushier growth. Best flavor is before flowering. Can be harvested year-round in warm climates; cut back after flowering to encourage fresh growth. Dry leaves by hanging in bundles in a dark, well-ventilated area for 1-2 weeks.
