Sow in biodegradable pots to avoid root disturbance. Mild Climates: Sow in fall for a cool-season harvest.

Growing Info
Harvesting: Harvest heads when they are well developed, firm, and solid when squeezed. Cut off heads at base with a sharp knife. Cabbages left in the ground beyond maturity are more subject to disease and splitting. Harvest in the morning if possible. If harvested in the heat, dunk in ice water to reduce "field heat" and increase storage time. Allow to drain before storing.
