Sow small batches outside for a long season of cut-and-come-again leaves. This is the usual UK way to grow mizuna in beds or containers.
Sow a small batch
every 3 weeksSow thinly around in shallow drills or scatter into prepared soil, then cover with a light layer of fine compost. Sow a fresh batch every 21 days for a steady supply of young leaves.
Thin seedlings
When the seedlings are large enough to handle, thin them so the strongest plants are left at apart. Snip extras off at soil level rather than pulling them up, so you don't disturb the roots of the plants you want to keep.
Protect from pests
Check plants from for slug and snail damage, and use fleece or mesh if flea beetle is pinholing the leaves. Keep the bed clear of weeds and water in the morning so growth stays steady.
Water regularly
every weekFrom , keep the soil evenly moist so the leaves stay tender and the plants do not run to seed in dry spells. Water at the base and avoid soaking the foliage late in the day.
Harvest leaves
every weekStart picking from once the plants are well rooted, taking outer leaves first or cutting whole plants just above the crown. Keep harvesting little and often, because regular picking encourages fresh growth through .

Why companion planting matters
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.

Basil
Basil is a fragrant, tender herb whose leaves are a staple of summer cooking. Native to tropical regions, basil is treated as an annual in temperate climates like the UK because it cannot tolerate frost. It thrives in warm, sunny conditions and can be grown in garden beds or pots for a steady supply of fresh, flavourful leaves throughout the summer.
Brussels Sprouts
Brussels sprouts are a hardy winter brassica (cabbage family) that form sturdy, leafy stems often around 60–90cm tall. They produce edible mini-cabbage buds along the stem from autumn through winter. Thanks to their cold tolerance, sprouts remain productive into late winter, and frost actually improves their sweetness.
Calabrese
Calabrese (broccoli) produces a large central head of tightly-packed green buds, followed by smaller side-shoots after the main head is cut. It’s a cool-season brassica crop. Grow it in full sun with fertile, well-drained soil and keep plants watered during dry spells. Harvest the heads while firm, then leave the stem in the ground to allow side-shoots to develop.
