Growing Info

Harvesting: For eating, harvest buds when they are still tightly closed, just before they begin to open (opened heads are tough). Cut the central bud first by cutting the stem with a sharp knife 2" below the bud. After harvesting, side shoots will produce smaller harvestable buds (a unique delicacy!).
