How to Grow Mibuna Green Spray Mustard
Sow seeds 4-6 weeks before the final frost date, or start indoors for transplanting. Sow 5-6 seeds half-inch deep and 4 inches apart in fertile, well-drained soil in full sun to part shade. Sow every two weeks for a continuous harvest. Start seeds indoors 3-4 weeks before transplanting outside for an early harvest. The flavor is best when grown in fertile soil and watered well. Work compost or mature manure into the earth to increase fertility and moisture retention. Mibuna is outstanding for undercropping and intercropping.
Thin the seedlings to 1 plant every 12 inches once the true leaves establish. Do not worry about bolting unless high temperatures persist. Mibuna does very well when grown in containers and unheated greenhouses throughout the year. Some gardeners have begun using this plant as a cover crop with success. With this crop, your imagination is your limit!
Harvesting Mibuna Green Spray Mustard
Like lettuce, harvest large outer leaves while allowing smaller leaves to mature. Sharp scissors or a knife are the only tools needed.
Culinary Tips
Excellent for salads, pickling, steaming, and stir-fry. Mibuna is characteristic of fresh Japanese vegetables. Prepare this green as you would any mustard green; take care not to overcook them, and a little seasoning goes a long way.
