Microgreen-Sorte
Spinach Microgreens
Spinach microgreens are the young shoots of Spinacia oleracea, harvested above the growing medium. They belong to the amaranth family and have a mild, delicate green flavour.
Variety profile
- Botanical name: Spinacia oleracea
- Typical growing time: 12–21 days
- Difficulty: demanding
- Flavour: mild and delicately green
Seeds and preparation
Use only fresh, food-safe seeds. Cool, even germination conditions are preferable to warmth and waterlogging. Use only untreated, viable seeds intended for producing edible sprouts or microgreens. A small germination test before the main sowing saves space and reveals differences between seed lots.
Sowing and germination
A clean, shallow tray with drainage and a separate catch tray make cultivation easier. Moisten the growing medium evenly without standing water. Distribute the seeds closely but without overlapping. During covered germination, check odour, moisture and seedling development daily.
Light, water and crop management
Spinach often germinates more slowly and unevenly. Small test trays help determine seeding density, temperature and harvest time for each lot. Once the cotyledons are upright, provide bright, uniform light. Water from below, drain excess water and allow the surface to dry slightly between waterings.
Harvesting and use
Harvest with clean scissors just above the growing medium when the cotyledons are fully open and the shoots are dry. Remove unused hulls and damaged plants. The shoots are particularly suitable for mild salads, sandwiches and cold dishes. Add them just before serving.
Putting nutrients into perspective
Mature spinach is a source of iron, but no fixed iron content for its microgreens can be inferred without analysis. Variety, seed lot, light, temperature, irrigation and harvest age affect composition. This information is not a substitute for laboratory analysis or medical advice.
Hygiene and common problems
Dense, warm and humid crops can encourage plant diseases and undesirable microorganisms. Keep hands, trays and tools clean, use drinking-quality water only and do not consume suspect batches. Common problems include patchy germination, long pale stems, adhering hulls and mould. Change seeding density, airflow, light and moisture only gradually and document each adjustment.
Conclusion
Spinach microgreens broaden the selection with a distinctive crop-specific flavour. Lot-specific germination tests, clean bottom watering and a documented harvest window enable reliable assessment.
