Microgreen ‘Mustard Green’ Seeds
Botanical Name: Brassica juncea
Mustard greens are a popular choice for growing microgreens at home or in small gardens. They’re fast to grow, easy to manage, and full of flavour. The young leaves have a bright green colour and a spicy taste that works well in salads, wraps, and Asian-style dishes.
Why Grow Mustard Green Microgreens?
- Quick harvest: Ready to cut in just 7–10 days.
 - Bold flavour: Adds a peppery kick to your meals—great for spice lovers.
 - Eye-catching colour: Vibrant green leaves that mix well with other microgreens.
 - Nutrient-rich: A natural source of vitamins A, C, and K, plus antioxidants like sulforaphane (source).
 
How to Grow Mustard Green Microgreens
- Pre-soak: Not needed.
 - Seeding Rate: 5 grams per small tray (e.g. punnet-sized).
 - Growing Medium: Use organic soil, coco coir, or grow hydroponically on hemp mats.
 - Tray Setup: Add 2–3 cm of soil or coir. Flatten and moisten the surface. Sprinkle seeds evenly and mist with water.
 - Blackout Period: Cover with another tray or lid and place in a dark, ventilated spot for 2–3 days. Water 1–2 times daily.
 - Light Exposure: When shoots reach 3 cm, remove cover and place in indirect sunlight or under grow lights. Continue watering.
 - Harvest: Cut 1–2 cm above the soil line when plants are 6–8 cm tall (about day 7–10).
 
Helpful Growing Tips
