Harvest Tips
Harvest when heads are 6-8 inches tall and still tender, typically 45-60 days after planting. Cut entire head at soil level with a sharp knife, or harvest outer leaves first and allow center to continue growing for extended production. Early morning harvest yields crispest leaves. Prize Choy matures quickly and should be harvested promptly—leaving plants too long in warm weather causes bolting and bitterness.
