Planting & Care

Sow Choy Sum seeds directly in the garden 1/4 inch deep, about 2-4 weeks before the last frost date for a spring crop, or in late summer for a fall harvest. Seeds germinate best at soil temperatures between 60-75°F (15-24°C) and typically sprout within 5-10 days. Thin seedlings to stand 6-12 inches apart to allow room for growth. Keep the soil evenly moist but not waterlogged, and provide consistent moisture to prevent bolting.

Choy Sum benefits from regular watering and a side dressing of compost or balanced fertilizer. Harvest leaves and stems when plants are young and tender, or cut the entire plant at the base. For a continuous supply, sow seeds every 2-3 weeks during the growing season. Monitor for common pests like aphids and flea beetles, and use row covers if necessary.
