Mizuna 'Early Mizuna' problems — and how to fix them
Mizuna 'Early Mizuna' (Brassica rapa var. nipposinica 'Early Mizuna') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bolting
Heat and long days push plants to flower and turn leaves harsh. Sow in cool windows, cut regularly when young, and keep moisture consistent.
Flea beetles
Riddle the thin leaves with tiny holes, the most common mizuna pest. Grow under fine mesh and keep plants moist and fast-growing to outpace damage.
Slugs and snails
Hide in the dense rosette and graze tender new growth in damp weather. Use barriers or traps and harvest in dry conditions to keep leaves clean.
Downy mildew
Yellow blotches with grey undersides in cool, humid conditions. Improve airflow with wider spacing, water at the base, and remove affected leaves.
