    ABOUT

    Green Nasturtium microgreens are one of the few crops that look as impressive on the plate as they taste — those wide, shield-shaped leaves on flushed pink stems are a chef's garnish dream straight from the tray. Bite into one and you'll get a clean, sharp, persistent peppery heat that builds slowly on the palate, quite unlike any other microgreen — more tenacious than radish, more complex than arugula. Scatter a few chopped leaves over street tacos, fold them into a vinaigrette, or blend them into soft goat's cheese for an instant flavour upgrade. Nasturtiums also hold the record for the highest lutein concentration of any edible plant — reason enough to start a tray today.

    GROWING INSTRUCTIONS
    1 Soak your seeds in lukewarm water for 2–6 hours before planting — the seeds have a hard, powdery outer coat and the water helps life push through. The soaking water will turn murky; rinse the seeds in a strainer before use. You'll notice the seeds swell slightly — a good sign.
    2 Fill your tray with a quality potting mix or compost, tamp it gently to an even surface, and mist the soil so it is uniformly moist but not waterlogged. Spread the pre-soaked seeds across the surface with a little space between each one — nasturtiums grow large, so resist the urge to crowd them.
    3 Cover the seeds with a thin layer of soil (about 5 mm) and mist again. This 'buried' blackout method keeps the large seeds moist and dramatically improves germination. Place a second tray on top as a weighted lid, or simply cover with a dark cloth.
    4 Keep the tray in blackout for 5–8 days at 18–22 °C. Check moisture every day — nasturtium seeds dry out easily and slow germination. Around day 4–5 you'll see the first pale, curly shoots pushing up through the soil — this is the exciting moment that makes the wait worthwhile.
    5 Once most seedlings have emerged and are lifting the cover, remove the blackout and move the tray into bright light or under a grow lamp. Nasturtiums are hungry for light — give them as much as possible from this point on. Watch those pale, stringy seedlings transform into vibrant green within 24 hours.
    6 Water from the bottom by placing the tray in a shallow dish of water (pH 6.0–6.5) and letting the soil absorb moisture for a few minutes — this keeps the leaves dry and Maintain good airflow around the tray. At 18–22 °C the leaves will colour up beautifully.
    7 Harvest with clean scissors at soil level between day 14 and day 21, once the cotyledon leaves are fully open and the first true leaf may be emerging. The stems will be firm and the leaves plump and fragrant with that characteristic peppery sharpness — rinse gently and use immediately for the best flavour.
