Mustard Microgreens — also known as Sarson Microgreens — are the young, tender seedlings of Brassica juncea, a member of the Brassicaceae family native to South Asia and Central Asia. Harvested at the cotyledon or first-leaf stage, their flavour is pungent, peppery and mustard-like heat with bold intensity, and their colour is green. Ready to cut in just 7–10 days from sowing, Mustard Microgreens are one of the easiest ways to grow fresh, homegrown greens indoors all year round, with no garden space required.
These seeds germinate in 2–3 days on cocopeat, coco coir, or soil-less growing mix spread about 1–1.5 inch deep in a shallow tray. Soaking: no soaking needed. Keep the tray covered in darkness for 2–3 days until the shoots are up, then move it to bright indirect light to partial direct light. Mist gently with the 1 Litre Garden Spray Pump on its fine-mist setting to keep the medium moist without disturbing the seeds, and harvest with Multipurpose Garden Scissors (Small) when shoots reach 1–3 inches. Beginner-friendly and low maintenance, Mustard Microgreens grow happily at 20–28°C in any Indian climate zone.
Rich in vitamins and antioxidants typical of the parent vegetable, Mustard Microgreens add a pungent note to salads, garnish, sandwiches and smoothies. Once cut, they stay fresh for 3–5 days refrigerated — refrigerate in an airtight container or a paper towel-lined box. For a tray of contrasting colours and flavours, grow them alongside our Radish (मूली माइक्रोग्रीन) Microgreens Seeds, or try the 6-in-1 Microgreens Seeds Combo Pack to sample six varieties at once.
Microgreens are among the most nutrient-dense foods you can grow at home. With a pack of Mustard microgreen seeds, a shallow tray and a sunny window, you can harvest fresh greens within two weeks and sow a new tray every 7–10 days for a continuous supply — perfect for home cooks, fitness enthusiasts, kids' science projects, cafés and home-based microgreen businesses.
How to Grow Mustard Microgreens at Home
What You Need
Sowing Mustard Microgreens Seeds
Pre-moisten the growing medium and level it gently. Soaking: No soaking needed. Scatter the seeds evenly across the surface so they are close but not piled on top of each other. Sow densely; mustard sprouts quickly and is very beginner-friendly. Mist the surface well after sowing.
Germination and Blackout Period
Cover the tray with another tray or lid and keep it in a warm spot (20–28°C). Seeds germinate in 2–3 days. Keep them in darkness for 2–3 days — this encourages strong, upright stems. Check daily and mist if the surface looks dry; humidity should be moderate to high during germination.
Light and Watering
Once the shoots are up, remove the cover and place the tray in bright indirect light to partial direct light. A bright windowsill or balcony works well; leggy, pale shoots mean they need more light. Water with a fine mist or by bottom-watering (pour water into an outer tray so the medium soaks it up from below) to keep the leaves dry. Ensure good ventilation after blackout to prevent mould.
Harvesting Mustard Microgreens
Snip with scissors just above the growing medium. Mustard Microgreens are usually ready in 7–10 days. Cut just above the growing medium with clean scissors, ideally in the morning when the greens are crisp. Regrowth potential is low-moderate (varies by species; usually single-cut crop), so most growers resow a fresh tray rather than waiting for a second cut.
Storage and Freshness
Refrigerate in an airtight container or a paper towel-lined box. Harvested mustard microgreens stay fresh for 3–5 days refrigerated. Rinse just before eating rather than before storing. Store unused seeds in a cool, dry, airtight container away from direct sunlight.
Preventing Mould and Damping-Off
Avoid overwatering, ensure airflow, don't overcrowd seeds, remove any mouldy patches promptly. Common problems include overwatering leading to damping-off/mould, uneven germination, leggy growth from low light. Learn more about how microgreens are grown and used.
