Mizuna / Japanese Mustard (Brassica rapa var. nipposinica)

Sow the seeds directly into the bed or in a greenhouse from April to September. However, Mizuna also grows when sown in an unheated greenhouse from autumn to spring and also forms leaves during winter. The plant is intolerant of drought, it needs to be grown in moist, fertile soil to form lush leaves. Fairly hardy and tolerating summer heat, Mizuna doesn't like frost and raw weather. It's a fast-growing plant and can be harvested already some weeks after sowing and you can continue cropping for 10 months before it will start to produce seeds.
