Description

(Brassica juncea). The leaves of this gargantuan mustard from China reach an astounding 3 feet long and 1.5 feet wide. We enjoy this variety for its large succulent leaves and thick, crunchy white midrib. The flavor is exceptionally sweet and mild for a mustard, making it suitable for raw eating in salads and a top choice for pickles, stir fry, and steaming.

Growing Tips: Prefers well-drained, rich soil with a pH of 6.0-7.5. Keep soil consistently moist but not waterlogged. Full sun to partial shade; however, it requires 6-12 hours of sun daily. Mustard greens grown in partial shade tend to be more tender and less prone to bolting in warmer weather.

When to Grow

Plant in early spring or late summer for a fall harvest. Best grown in cool weather; avoid planting during extreme heat. The perfect temperature for Chinese Giant Leaf is 55-70 degrees F. Check local freeze dates to avoid planting too early or too late in the season.

How to Sow and Plant

  • Direct Sowing: Sow seeds 1/4 inch deep directly in the garden, and space plants 12 inches apart.
  • Transplanting: Start seeds indoors 4-6 weeks before the last freeze date and transplant seedlings outdoors when they are large enough to handle.

How to Grow

Thin seedlings to 6-12 inches apart when they are 2 inches tall. Use mulch to retain moisture and suppress weeds. Regular watering is crucial, especially in dry conditions. Harvest leaves when they are young and tender for the best flavor.

How to Save Seeds

  • Brassica juncea is capable of self pollinating, but insects can cross pollinate the flowers with other varieties of B. juncea if growing within a 2-mile radius. If saving seeds, isolate the plants from other B. juncea varieties by 2 miles.
  • To save the seeds, allow pods to brown, dry, and become crispy. Shake pods into a paper bag to remove seeds. Store seeds in a cool, dark, dry location.
