The growing point of a mizuna plant sits at the very center of the crown, right at soil level, tucked among the bases of the stems. Everything above it can be removed and the plant will push a new flush from that point within days. Cut into it and the plant is done, no matter how healthy the roots are.
In practice that means shearing about one inch (2.5 cm) above the soil, or a little higher if the crown is on a raised neck. Leaving an inch of stubble looks wasteful and feels wrong the first time, but that stubble is what feeds the regrowth. Cutting flush with the soil is the single commonest reason a bed of mizuna gives one crop instead of four.
Use scissors or a sharp knife and cut cleanly. Tearing the stems leaves ragged tissue at the crown that rots in wet weather and gives soft rot a way in.
| Method | Where to cut | Regrowth | When to use it |
|---|---|---|---|
| Shear the band | 1 in (2.5 cm) above soil | 3 to 4 more cuts | Baby leaf sown thickly |
| Pick outer stems | At the base of each stem | Continuous for months | Full-size plants at wide spacing |
| Lift the whole plant | Cut the root below the crown | None | Clearing the bed, or before hard frost |
Timing: size and flavor move together
Mizuna is edible at every stage, so the question is what you want it for rather than whether it is ready. Leaves at four inches (10 cm) are mild, tender and best raw. At eight inches (20 cm) they carry a definite mustard bite and the stems have real crunch, which is what you want for a mixed salad or a fast stir-fry. Past twelve inches (30 cm) the stems turn fibrous and the heat is assertive enough that most people prefer them cooked.
Nothing goes bad if you leave it, but the window is not indefinite. Once the plant starts making a flower stem the older leaves toughen quickly, and once you can feel a thickening bud at the center of the crown you have perhaps a week of good picking left.
Pick in the morning where you can. Leaves cut before the day warms hold far more water, stay crisp for days in the fridge, and wilt within an hour when cut in afternoon heat.
| Leaf length | Days from sowing | Flavor | Best use |
|---|---|---|---|
| 3 to 4 in (8 to 10 cm) | 21 to 30 | Mild, barely peppery | Raw, as the base of a salad |
| 6 to 8 in (15 to 20 cm) | 35 to 45 | Clean mustard bite | Mixed salad, quick pickles |
| 10 to 12 in (25 to 30 cm) | 50 to 60 | Peppery, stems crunchy | Stir-fry, soup, braising |
| Over 14 in (36 cm) | 65 plus | Hot, stems fibrous | Cook it; strip the toughest stems |
How many cuts you actually get
Three to four cuts from one sowing is realistic in cool weather with decent feeding. Each flush is a little smaller and a little more peppery than the last, because the plant is drawing on a crown that is slowly running down. Knowing that the fourth cut will be thin is useful: it tells you when to sow the replacement row rather than waiting until the bed is bare.
- Cut, water, feed the same day Shearing removes most of the plant's leaf area and all of its current nitrogen store. Water thoroughly and give a liquid feed within a few hours so the new flush starts immediately rather than after a week of hesitation.
- Expect the next cut in two to three weeks In mild weather regrowth is fast. In cold weather it can take four to six weeks, and in midwinter it may simply hold and give you nothing until light returns. That pause is normal and the plant is not dying.
- Sow the replacement at the second cut Do not wait for the stand to fail. Sowing a new row when you take the second cut means the new plants are ready roughly as the old ones tire, and you never have a gap.
Regrowth after a cut is noticeably more peppery than the first flush even under perfect care. If mildness matters more to you than quantity, take one or two cuts and start again rather than pushing to four.
After picking, and what to record
Do not wash mizuna until you are going to use it. Wet leaves in a bag go slimy in a couple of days. Store unwashed in a loose bag or a lidded box with a dry sheet of kitchen paper, and it keeps five to seven days. Wilted leaves recover almost completely if you stand the cut stems in cold water for half an hour, so a bunch that has flopped on the way in is not wasted.
Keep a note of the date of each cut for each row and roughly how much came off it. Two seasons of that record tells you exactly how many cuts your conditions support and how long regrowth takes at each time of year, which is the number that lets you plan a continuous supply instead of guessing.
