Maintain consistent watering and even moisture. Mulch around plants to retain moisture and cool soil. Monitor for pests. Begin harvesting outer leaves once plant has 6-8 leaves.
Leaf Production & Harvest
15-25 daysMature plant with abundant tender leaves; plant remains in vegetative state with continuous new leaf formation from center
Continue consistent watering. Harvest outer leaves regularly to encourage more production and delay bolting. Remove any yellowed or damaged leaves. Maintain cool conditions.
Bolting
