Harvest Tips
Harvest when heads are full and firm but still tender, typically 50-70 days after planting. Cut the entire head at soil level with a sharp knife in early morning when crisp. For extended harvest, pick outer leaves while leaving the center to continue growing. Do not delay harvesting as warm weather causes bolting and bitterness.
