For mature leaves, wait until the plant reaches 6-8 inches tall. Cut entire plants at the base or harvest individual outer leaves as needed.
Harvest in the morning when leaves are crisp and flavorful. Use clean, sharp scissors or a knife to avoid damaging the plant.
Storing Fresh Mizuna
Proper storage extends the shelf life of freshly harvested mizuna. Rinse leaves gently in cool water to remove dirt and pat dry with a clean towel.
Store unwashed mizuna in a plastic bag with a damp paper towel in the refrigerator. It will stay fresh for up to a week.
For longer storage, blanch and freeze mizuna. Alternatively, add it to stir-fries, hot pots, or juices for immediate use.
