What does mizuna taste like?

Mild peppery mustard — much milder than mature mustard greens, but with a clear mustard-family edge. Young leaves are gentle enough for salads; older leaves get sharper and more mustardy. The flavour is between rocket and watercress — peppery but not aggressive. Excellent in mixed salad bowls (the feathery leaves add texture and visual variety), stir-fries, sushi rolls, sandwiches. Use within 2–3 days of picking — flavour and texture both fade with storage.

When can I pick mizuna?

4–6 weeks after sowing, when leaves are 10–15 cm tall. Cut-and-come-again: cut whole rows 2–3 cm above the soil, the plants regrow in 7–10 days, repeat 3–4 times before bolting. Mature plants: pull whole plants for use as a stir-fry green (leaves to 30+ cm). Most UK kitchen gardeners use the cut-and-come-again method for maximum salad supply from a small row.

Why does my mizuna keep bolting?

Heat + day length. Mizuna bolts to flower in long warm days — exactly what summer offers. Three strategies. (1) Sow in cool months: March–May for spring crops, August–October for autumn/winter. (2) Skip June and July: hot-season sowings bolt before producing usable leaves. (3) Sow under cover in September: mizuna's best season is autumn–winter undercover, when day length is short and heat isn't an issue.

Is mizuna the same as mustard greens?

Same family, different species, different flavour intensity. Mizuna (Brassica rapa var. nipposinica): mild peppery flavour, feathery leaves, the salad-friendly choice. Mustard greens (Brassica juncea — see separate mustard-greens slug): stronger peppery flavour, broader leaves, more often cooked than eaten raw. Red Giant mustard and Green-in-Snow mustard are the typical mustard greens; Mibuna is a smooth-leaved relative of mizuna. Both grow under the same UK conditions.

Can I grow mizuna under a cloche in winter?

Yes — this is mizuna's most useful UK growing window. Sow in late August or early September under a low polytunnel, cloche, or cold frame. The plants establish before frosts and crop from October through to March, growing slowly through the coldest months but consistently producing tender leaves. No competition from outdoor crops — mizuna's autumn-winter window fills a real gap in UK home-grown salad supply.

How do I stop slugs eating my mizuna?

Combine multiple controls — no single method is 100% effective on tender salad greens. Apply at sowing: (1) Wool pellets scattered along the row. (2) Nematodes (Phasmarhabditis hermaphrodita) watered into the soil. (3) Hand-pick slugs in the evening after rain. Best long-term solution: grow mizuna under cover (cloche, cold frame, polytunnel) — slugs are largely excluded and the crop is much more reliable.

Mizuna

Brassica rapa var. nipposinica

Sow mizuna direct from March to October, in sun or part shade in moist soil — it's a fast-growing cool-season Japanese salad green with feathery deeply-cut leaves and a mild peppery mustard flavour, ideal for cut-and-come-again cropping. Mizuna is hardy (RHS H4–H5) and at its best in the cooler months — spring and autumn sowings produce tender leaves for weeks, while midsummer sowings bolt to flower quickly. One of the most useful UK undercover winter salads — sown in September it crops through to March from a cold polytunnel, cloche, or cold frame. Pick young leaves continuously by cutting at the base (cut-and-come-again — the plant regrows for 4–5 cuts). Slug attack is the main problem outdoors; flea beetle damages young plants in summer.
