Description CHINESE MICHIHLI 75 days. Chinese type cabbage Sweeter, milder flavor then regular cabbage. Tall, cylindrical heads average 18? tall and 4? across. Dark green outer leaves with a creamy white center. CULTURE: Spring-planted crops: Sow 2 seeds per cell, 1/4" deep in 72-cell plug trays. If possible, keep soil temperatures above 75F (24C) until germination and then maintain air temperature to 60–70F (16–21C). Transplant out in 3–5 weeks, around the last frost date (see BOLTING below), taking care not to disturb roots; water-in plants. Summer/fall-planted crops: Start seedlings as described above in mid to late June or direct seed from late May to mid-July as described below. DIRECT SEEDING:Sow 3–4 seeds every 12–18" (thin to one plant) in rows 18-30" apart from late May to mid July. BOLTING:This crop performs best in the gradually decreasing day length and cooler temperatures of late summer, but can be grown successfully in the spring if careful attention is paid to prevent bolting. For spring and early summer transplanted crops, be sure to wait until the last frost date to transplant or direct seed the crop. Young plants may bolt to seed prematurely if they are exposed to frost or over a week of sub 50F/10C nights.
