Product Description
Mizuna is a popular Japanese leafy green known for its delicate, deeply serrated leaves and mild mustard flavour. It has a fresh, slightly peppery taste that adds texture and colour to salads, sandwiches, stir-fries and Asian-style dishes.
This fast-growing brassica is suitable for both baby leaf and mature leaf production. Young leaves are tender and mild, while larger leaves develop a stronger flavour that works well in cooked dishes such as soups, noodles, sautés and hot pots.
Mizuna is an excellent choice for home gardeners, market growers and small-space gardens. It can be harvested as a cut-and-come-again crop, allowing repeated picking from the same plants when the central growing point is left intact.

How to Grow Mizuna
Sow Mizuna seeds directly into prepared garden beds or raise seedlings in trays for transplanting. Cover seeds lightly and keep the soil evenly moist during germination.
Plant into fertile, well-drained soil enriched with compost. Mizuna grows quickly and benefits from regular moisture, especially when grown for tender baby leaves and salad greens.
Harvest young leaves regularly to encourage fresh growth. In warmer weather, provide part shade to help maintain leaf quality and reduce stress.
For continuous production, sow small batches every 2–3 weeks during the growing season.
Harvest
Harvest baby leaves from around 20–30 days, or allow plants to mature for larger leaves. Pick the outer leaves first, leaving the centre intact for continued growth. For a full cut, trim plants above the growing point and allow them to regrow.
