Growing Green Mustard Microgreens for Commercial Harvest
Use approximately 10–15 g of seed per standard 10 × 20 inch tray as an initial trial range. Fine-tune the rate for your seed lot, 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 soil or coir-based growing medium with good drainage.
- 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 2–4 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
Green Mustard microgreens have a fresh, spicy and peppery mustard flavour. Their flavour is more pronounced than mild brassica microgreens such as broccoli or cabbage, making them particularly useful where the microgreen is intended to contribute flavour as well as visual appeal.
Use Green Mustard microgreens as a finishing garnish on savoury dishes or as a fresh addition to salads, sandwiches, wraps, burgers and mixed microgreen packs. Their mustard heat pairs particularly well with meat, seafood, eggs, cheeses and Asian-inspired dishes.
