Mizuna Cultivation Guide. Mizuma brassica is an oriental vegetable very easy to grow and very tasty, it can be consumed in a salad by picking some young leaves or confining them in a pot when the plant is more developed.

Scientifically it is known as Brassica Rapa Nipposinica and commonly called Japanese mustard. It belongs to the cruciferous family, being the mizuma a close relative.

Its particular flavor, a little spicy and the appearance of the serrated leaves, reminds us a little of arugula. It is a very simple crop so it is suitable for beginners. It is a plant that has a very fast growth, so we can consume it very quickly at the table.

WHEN AND HOW TO SOW

The best time to plant mizuna is during a period of cool weather, i.e. autumn and winter, even early spring. It grows at temperatures ranging from 7 to 23°C. One recommendation is that the colder the mizuna is, the tastier and milder tasting the leaves are.

As for how we are going to sow it, we are going to do it by direct sowing, although we can also do it in seedbed. We have to look for a place with soil rich in organic matter that receives direct sun or has very little shade. When it comes to sowing it, we can do it either by putting 2 or 3 seeds in each hole where we are going to sow it to ensure its germination.

IRRIGATION IN THE GUIDE TO MIZUNA CULTIVATION

In the Mizuna cultivation guide, we are going to help you in this section that creates as much controversy as doubts in the growers. In this case we are going to give you a solution. In case it is rainy season and the substrate or soil is wet, watering will be omitted. In normal conditions we will water it about 3 times a week, depending also on the heat that it is hot or not.

HOW AND WHEN TO HARVEST MIZUNA

You can start harvesting mizuna as soon as the plants form a set of true leaves and are at least 5 cm or more tall. This will normally happen about two weeks after planting.

You can also use the “cut-and-come-again” method to harvest the outer leaves. Cut the leaves you want to harvest about two centimeters above the crown. The inner leaves remain to continue growing and form a new plant.

It is also a plant that admits to be cut every X time and it will resprout again.
