| 20 days. The earliest Mustard Green we grow, Savanna Hybrid begins bearing huge, tasty green leaves less than 3 weeks after planting! The leaves are very uniform and quite abundant on strong plants, which hold their harvest in the field much longer than open-pollinated types. A superb choice for high performance and great yields, plus mild, fresh flavor. Sow seed outdoors in early spring or, for fall crops, 6 to 8 weeks before first fall frost. Space seedlings 1 to 2 inches apart in rows 15 inches apart. Pkt is 1/16 oz. (350 seeds). |
