Description of Mizuna

Mizuna is an annual plant that grows in a dense rosette and is known for its high yields. It is part of the Brassica family and is known for its mild, peppery flavor, which is slightly bitter compared to arugula. Its leaves and stems are edible and can be used in a variety of culinary dishes3​​2​.

Origin and History

Mizuna has its roots in Asia, where it has been cultivated for a long time, especially in Japan. In 2019, Mizuna was successfully grown on the International Space Station, underscoring its robustness and versatility.4​.

Guidance in Planting

Choosing the right place 

Mizuna thrives best in full sun in humus-rich, well-drained soil. It is recommended to add composted material to the planting area before planting5​.

 

Time of planting 

Plant Mizuna in mid to late spring to harvest before the summer heat. It can also be replanted near the end of summer for harvest in the cool weather of fall and early winter5​.

 

Seed selection and pre-germination 

Mizuna can be sown directly in the garden from spring to early winter. In loose soil, you sow directly in the vegetable area from June to August6​.

 

Planting techniques 

Sow Mizuna seeds ¼ to ½ inch deep, spacing 8 to 10 inches between plants if you are growing the plants for a harvest of leaves. If you sow Mizuna to be harvested as microgreens, you can spread the seeds and thin small plants for eating and let others grow to maturity.5​.

Care by Mizuna

Watering requirements 

Keep the soil evenly moist, but not too wet. Mizuna, like most vegetables, prefers regular watering, especially during the growing season5​.

 

Fertilization and soil improvement 

Fertilize Mizuna with a weak fish emulsion solution, especially if you harvest the plants heavily during the growing season5​.

 

Pruning and thinning 

There is no specific information available on pruning and thinning Mizuna. However, it is good practice to thin the plants to ensure sufficient air circulation and room for growth.

 

Pest and Disease Prevention 

Protect Mizuna from flea beetles with row cover and avoid planting Mizuna after cabbage or other cabbage family crops to prevent diseases related to the cabbage family​5​.

Mizuna in different climates

Mizuna in hot climates 

Mizuna grows best in cool weather, but can be grown in warmer climates if planted in fall or early spring to avoid the hottest months.

 

Mizuna in cooler climates 

Mizuna can withstand frost near maturity and can be grown through the winter in a plastic tunnel or cold frame5​.

Harvest and Storage

When and how to harvest Mizuna 

Harvest Mizuna when the leaves reach a desirable size, typically 40 days after sowing. The leaves can be cut off and the plant will continue to produce new leaves for a continued harvest.

 

Storage tips 

After harvesting, wash, bag and store Mizuna in a cool refrigerator where it can last for more than a week. Mizuna can also be blanched and frozen for later use, just like other vegetables such as chard and spinach7​.

Applications

Culinary Applications 

Mizuna is extremely versatile in the kitchen, making it a favorite among chefs and food enthusiasts. The mild mustardy, peppery flavor makes it suitable for a variety of dishes, from fresh salads to stir-fries and soups. The young, tender leaves are particularly suitable for raw consumption in salads, while the more mature leaves and stems can be sautéed or added to soups and stews. Mizuna can also replace basil or spinach in your favorite pesto recipe1​.

 

Recipes and Cooking Tips 

There are many recipes available that highlight Mizuna's unique taste and texture. For example, a Mizuna Quinoa Salad with Lemon Spring Onion Vinaigrette or adding Mizuna to miso soup and grain salads can offer a new twist on traditional dishes.2​​3​.

Mizuna and Sustainability

Benefits of growing Mizuna locally 

Growing Mizuna locally can have several benefits, including fresher produce, lower transport emissions, and support for local agriculture. In addition, as demonstrated by Mizuna Gardens, sustainable agricultural practices involving the cultivation of Mizuna can contribute to environmental and economic sustainability, especially in relation to land management​4​.

 

Reduction of food waste 

By growing Mizuna locally and harvesting as needed, food waste can be minimized. Mizuna can be grown in a "cut-and-come-again" style, where leaves are harvested as needed, allowing the plants to continue producing new leaves.

Summary of Important Points 

Mizuna is a nutritious, versatile and robust leafy vegetable that is relatively easy to grow. It has a long history in Asian culinary tradition and is beginning to gain popularity globally. Its role in sustainable agriculture and the potential for local cultivation highlight its value beyond the kitchen.

 

Future Trends in Mizuna Cultivation
