Harvest Tips
Harvest basil microgreens at 10-14 days when the first true leaves are fully developed (2-3 inches tall). Use clean scissors or a sharp knife to cut just above the soil line. Harvest in the morning for best flavor. Basil microgreens can be harvested all at once or allowed to regrow for a second, smaller harvest.
