Seedling
1-2 weeksTiny cotyledons emerge, followed by the first true leaves with delicate, feathery appearance
Keep soil moist and provide bright light. Thin seedlings to proper spacing when 1-2 inches tall. Protect from slugs and snails.
Vegetative Growth
2-3 weeksPlant develops 4-6 true leaves; feathery foliage becomes more pronounced and spreads outward
Maintain consistent moisture and cool temperatures. Begin light feeding with balanced fertilizer every 2-3 weeks. Mulch to retain moisture and keep soil cool.
Leaf Development
1-2 weeksRosette expands with increasingly divided, lacy leaves; plant becomes bushier and fuller
Continue consistent watering and feeding. Monitor for pests like flea beetles. Provide shade cloth in summer heat (above 75°F) to prevent bolting.
Harvest-Ready
2-4 weeks or ongoingPlant reaches 8-12 inches tall with abundant, tender feathery leaves ready for harvest
Begin harvesting outer leaves when plant is 6-8 inches tall. Regular harvesting encourages more leaf production. Keep soil evenly moist.
Bolting (End of Season)
Variable, signals end of productive seasonPlant sends up a central flower stalk; leaves become tougher and more bitter
Harvest immediately if quality is still acceptable, or pull plant and compost. Bolting accelerates in warm weather (above 75°F) and long daylight hours.

Harvest Tips
Begin harvesting outer leaves when plant is 6-8 inches tall using cut-and-come-again method; this encourages continued leaf production. For baby greens, harvest entire plant at 25-30 days. Cut leaves at soil level or pinch off individual outer leaves. Harvest in morning for best flavor and texture. Regular harvesting extends productivity for 2-4 weeks. Mizuna is best eaten young and tender; flavor becomes more peppery and texture tougher with age or heat stress.
Fun Facts
- 🌱 Mizuna is native to Japan and has been cultivated for centuries; its name means 'water greens' in Japanese, reflecting its preference for consistently moist soil.
