Mizuna: A Versatile and Delicate Green Mustard


Mizuna is a versatile and delicate green mustard that has a nice bitter flavor. This Japanese mustard is frequently harvested for industrial salad mix manufacture, but it can also be cultivated quite easily for home use.

Tips for Keeping Your Plants Healthy

  • Mizuna is a fairly easy plant to grow and care for, however there are a few things you can do to ensure that your plants stay healthy:

Lighting and Temperature

Mizuna will grow in full sun or part shade, however it prefers cooler temperatures and will bolt (go to seed) if it gets too hot.

If you’re growing mizuna indoors, place your plants near a sunny window. A south-facing window is ideal.


Mizuna prefers rich, well-drained soil. If your soil is heavy or clay-like, mix in some sand or organic matter to improve drainage.

Mizuna will also do well in a container garden. Choose a pot that’s at least 12 inches wide and has drainage holes.


Mizuna is a fast-growing crop, so it’s important to fertilize regularly. Apply a balanced fertilizer (such as 20-20-20) once a month. You can also side dress with compost or manure every few weeks.


To encourage full, bushy growth, pinch back the tips of young plants. Pinching back also prevents the plant from going to seed.

Mizuna is ready to harvest when the leaves are about four inches long. You can cut the entire plant down to about two inches above ground level, or you can snip individual leaves as needed.


Mizuna prefers consistent moisture, so water your plants regularly—especially during hot, dry periods.

If you live in a hot climate, consider planting mizuna in partial shade to prevent the plant from bolting (going to seed).


Mizuna will reach a height of five to seven inches and a width of between ten and 15 inches.


Mizuna is a fast-growing crop that will produce flowers and seeds within the first year if left in the soil. The plant is biennial, meaning it will produce seeds in its second year of growth before dying.

If you’re growing mizuna for the greens, you can prevent seed production by regularly harvesting the leaves.

Common Pests

Mizuna is a hearty vegetable that can withstand a lot of wear and tear, but even this hardy veggie isn’t immune to pests. A common brassica disease, unfortunately, afflicts Mizuna quite often.

The good news is that this disease is easily controlled with row cover. The bad news is that Mizuna is also quite attractive to certain insects, who will feast on its leaves given the chance.

The most damage is done by beetles, but snails, whiteflies, and aphids can also cause problems if they’re not kept in check. Regular monitoring and quick action when pests are spotted are the best ways to protect your Mizuna crop.

Mizuna Varieties

Gardening is a fun and rewarding hobby, and one of the best things about it is that you can grow pretty much whatever you want. If you’re interested in growing your own mizuna, there are a few things to keep in mind.
