Summer Red cabbage 'Ruphus'

800 seeds

Sow seeds indoors 6-8 weeks before the last frost date or directly outdoors after the frost danger has passed. Plant seeds about 1/4 inch deep in well-draining, fertile soil. Space them 12-18 inches apart to allow room for the heads to form. Cabbage thrives in full sun and prefers cool temperatures (55°F - 75°F/13°C - 24°C). Keep the soil consistently moist but not waterlogged, and water regularly to prevent stress. Fertilize with compost or a balanced fertilizer to support healthy growth. Thin seedlings to ensure proper spacing for head development. Cabbage 'Ruphus' matures in about 70-90 days. Harvest when the heads are firm and fully formed, usually in mid-summer.
