Step-by-Step Growing Guide

Mizuna (Brassica rapa var. nipposinica) is one of the fastest, most versatile salad greens available. It thrives in well-draining, moderately fertile soil with a pH of 6.0–7.0. Direct sow from early spring through autumn, broadcasting seeds over a prepared seedbed or drilling in rows 20 cm apart at 0.5 cm depth. For baby leaf production, sow thickly at 1–2 cm apart and cut at 5 cm height. For full-sized rosettes, thin to 20–25 cm. Water regularly and evenly — drought stress triggers premature bolting. Apply a balanced liquid fertiliser every 2 weeks for continuous cut-and-come-again harvest. Mizuna tolerates light frost to –5°C, making it ideal for autumn and winter growing under low tunnels or cloches. In warm climates, it bolts rapidly in temperatures above 25°C; choose shade-cloth-protected beds in summer. Succession sow every 3 weeks for uninterrupted supply.

Common Pests & Problems

Flea beetles (Phyllotreta spp.) create tiny round shot holes across leaves — most damaging to seedlings; protect with fine insect mesh immediately after sowing. Cabbage white butterfly (Pieris brassicae) and cabbage moth (Mamestra brassicae) caterpillars chew large holes in leaves; use fine mesh exclusion netting to prevent egg-laying. Aphids, particularly cabbage aphid (Brevicoryne brassicae), colonise growing tips causing distorted leaves; apply insecticidal soap or neem oil and encourage predators. Downy mildew (Peronospora parasitica) appears as yellow patches on leaf surfaces with grey-white mould beneath in cool, humid conditions; improve spacing and avoid wet foliage.

Harvest & Storage

Begin harvesting mizuna as soon as plants reach 10–15 cm for baby leaves (about 21 days from sowing). For cut-and-come-again, use scissors to cut leaves 2–3 cm above the crown, allowing the plant to re-sprout for multiple further harvests. A single sowing typically yields 3–5 cuts before quality declines. Full rosettes for whole-plant harvest are ready at 30–45 days. Mizuna wilts rapidly after cutting; harvest in the cool morning and refrigerate immediately in a damp cloth or sealed bag. It keeps for 3–5 days in the refrigerator. Mizuna does not freeze or dry well — consume fresh or use within days of harvest.

Popular Varieties

Kyoto Mizuna is the classic form with deeply serrated, feathery green leaves and white stems; the most widely grown variety for both commercial baby leaf and home garden production. Red Komatsuna is a closely related red-stemmed green with a similar but slightly more mustard-forward flavour and striking colour for salad mixes. Waido Mizuna is a more compact selection with broader, less deeply cut leaves and a milder, more spinach-like flavour suited to those sensitive to peppery notes. Mibuna is a close relative (Brassica rapa var. nipposinica) with smooth, strap-shaped leaves rather than feathery ones and a slightly stronger, more mustard-like flavour.
