How to Grow Green Mustard Microgreens in Singapore
Green Mustard microgreens can be grown indoors throughout the year in Singapore. For a standard 10 × 20 inch microgreen tray, approximately 10–15 grams of seed provides a useful starting sowing rate. For smaller home-growing trays, reduce the quantity proportionally and aim for even coverage without heavily overlapping the seeds.
- Prepare the tray.
Add approximately 3–4 cm of moist growing medium to a shallow tray and gently level the surface. Quality soil, coir and purpose-made hemp growing mats are suitable options. - Sow evenly.
Spread the Green Mustard seeds evenly across the growing surface. Aim for consistent coverage while avoiding heavy piles or overlapping clumps of seed. - Mist thoroughly.
Use a fine spray to moisten the seeds and growing surface evenly without washing the seeds into clusters. - Cover or stack the tray.
Cover the seeded tray with another tray or a suitable blackout cover during the initial germination period. Light, even pressure can help encourage more uniform establishment. - Maintain even moisture.
Check the crop regularly and keep the growing medium evenly moist without allowing it to become waterlogged. Mustard commonly germinates within approximately 3–7 days, depending on temperature and growing conditions. - Introduce light.
Once the seedlings have germinated and are pushing upwards, remove the cover and place the tray under suitable natural or artificial growing light. Maintain good airflow around the developing crop. - Water as the crop develops.
Bottom watering is useful once the seedlings are established because it helps keep the foliage relatively dry. Water as required rather than allowing the growing medium to remain saturated. - Harvest.
Green Mustard microgreens are commonly ready approximately 8–12 days after sowing. Cut the stems cleanly just above the growing medium when the seedlings have reached your preferred size, colour and flavour intensity.
Flavour & Uses
Green Mustard microgreens have a distinctive peppery, spicy flavour reminiscent of mature mustard greens, concentrated into tender young seedlings. They have considerably more bite than mild brassica microgreens such as broccoli, making them a good choice for growers looking for a stronger savoury flavour.
The intensity can vary according to growing conditions and the stage at which the crop is harvested. Their pronounced flavour also means a relatively small quantity can add noticeable character to a dish.
Fresh Green Mustard microgreens can be added to salads, sandwiches, wraps, burgers and grain bowls. They also work well with egg dishes, noodles and roasted vegetables, or as a fresh garnish added immediately before serving.
A Spicier Alternative to Mild Microgreens
Green Mustard is particularly useful for growers who enjoy brassica microgreens but want more flavour intensity than broccoli, cabbage or other mild varieties provide.
It can be grown as a standalone crop for a distinctly mustard-like flavour or combined with milder microgreens to add a peppery component to mixed trays and salad blends.
