Growing Wasabi Mustard Microgreens for Commercial Harvest
Use approximately 28 g of seed per standard 10 × 20 inch tray as an initial trial rate. Fine-tune the rate for your tray dimensions, medium, airflow and target harvest size. Aim for even coverage without dense piles of overlapping seed.
- Prepare trays. Fill with an evenly moistened growing medium, or prepare your chosen growing mat according to the manufacturer’s directions.
- Sow evenly. Distribute seed evenly across the surface. Pre-soaking is not required.
- Cover for germination. Mist as needed, then cover or stack trays according to your production method to maintain moisture and good seed-to-medium contact.
- Manage moisture. Keep the medium evenly moist without leaving it waterlogged. Germination commonly occurs within approximately 2–3 days under suitable conditions.
- Provide light and airflow. Uncover established seedlings and move trays into suitable natural or artificial light. Maintain good ventilation and monitor moisture closely.
- Harvest cleanly. Cut above the growing medium when the crop reaches your preferred size, commonly around 8–12 days after sowing.
Flavour & Culinary Uses
Wasabi Mustard microgreens have a bold, spicy mustard flavour with a sharp heat reminiscent of wasabi or horseradish. They are particularly useful where the microgreen is intended to contribute noticeable flavour as well as visual appeal. Use them as a finishing garnish for sushi-inspired dishes, seafood, poke bowls, salads, sandwiches, meat dishes and other preparations that benefit from a fresh mustard-like heat.
Wasabi Mustard is a variety of Brassica juncea and should not be confused with true Japanese wasabi (Eutrema japonicum).
