About

Mizuna (ミズナ(水菜), "water greens"), kyouna (京菜), Japanese mustard greens, or spider mustard is a cultivar of Brassica rapa var. niposinica.

How to grow it

Mizuna has been cultivated in Japan since ancient times. Mizuna was successfully grown in the International Space Station in 2019. It grows in hardiness zones 4 to 9. Mizuna prefers full sun or partial shade, well-drained soil and a pH of 6.5–7.0. It can be grown as a microgreen, sowing every 3 cm, or for its leaves, with 20 cm spacing.

Mizuna is best sown directly into the garden. While the ideal germination temperature is 55° to 75°F, the seeds will germinate in temperatures as low as 40°F. Mizuna is both tolerant of light frosts and very slow to bolt, making it an ideal vegetable for early spring or fall planting. While tolerant of partial shade, it will grow best in full sun, which means at least 6 hours of sun per day. Supplemental irrigation should be provided if rainfall is not plentiful.
