All about growing Mizuna from seed

Growing Guide

Mizuna is a Japanese green with a mildly spicy flavour, perfect for eating raw or lightly cooked. The plants take up little space and are ideal in containers as well as in the ground. Sow repeatedly for generous harvests across most of the year. They are easy to grow from seed most of the year, in sun or light shade and moisture-retentive soil.


Sow seed thinly direct outside or in a pot on the windowsill or in a greenhouse at 3 to 4 weekly intervals for regular harvests throughout the year. When sowing outdoors, sow seed 5mm deep, in drills 30cm apart. Thin seedlings to 25cm apart, or leave unthinned as baby salad
leaves. For indoor sowing thin to 2 seedlings per 9cm pot.

Keep the soil moist, watering in dry spells, to ensure consistent growth and prevent plants running to seed (bolting) prematurely. Give shade in hot weather, to prevent the leaves becoming tough and unpalatable. Cover with fleece or make summer sowings in a spot that gets some light shade.

Top Tip

Prefers cool, damp climates and is cold tolerant, so will usually continue cropping through autumn and winter, especially if given some protection.When harvesting pick a few leaves from several plants.
If you take lots of leaves from one plant, growth will be weakened.
