Early Jersey Wakefield Cabbage is very hardy and doesn’t mind cooler weather one bit! If you want to start early, plant your cabbage indoors about six to eight weeks before the last Spring frost. After four weeks, transplant outdoors to take advantage of the crisp, cool nights. Conical, solid heads produce a tightly wrapped small core that is firm when mature. Harvest when heads are between four and five inches in diameter. Early Jersey Wakefield Cabbage holds well in the garden for up to three weeks after reaching maturity.
