Harvest Tips
Begin harvesting when plants reach 6-12 inches tall. For continuous harvest, pick outer leaves progressively while leaving center to grow, or cut entire plant 1-2 inches above soil line for regrowth. Morning harvest provides crispest leaves. In cool seasons, plants can produce for 2-3 weeks with multiple harvests. Red Choi is most tender when harvested young; older leaves can become tougher.
