Seedling
7-10 daysTiny true leaves emerge with characteristic feathering visible within 5-7 days. Cotyledons are simple and smooth; first true leaves show the fine, lacy pinnation.
Keep soil consistently moist. Thin seedlings to proper spacing once they have 2-3 true leaves. Provide bright light to prevent legginess.
Vegetative Growth
15-25 daysPlant develops the full rosette form with increasingly feathery, finely divided leaves. Leaves are bright green and tender, growing rapidly outward from the center.
Maintain consistent moisture and regular watering. Apply balanced fertilizer every 2-3 weeks. Remove any yellowing outer leaves. Monitor for flea beetles and other pests.
Pre-Harvest Maturity
5-10 daysRosette reaches full size with abundant fine-textured leaves. Plant is bushy and full; leaves remain tender before flowering begins.
Increase watering frequency in warm weather to delay bolting. Begin harvesting outer leaves as needed. Keep soil cool with mulch in summer succession plantings.
Harvest
Continuous or 1-2 harvestsLeaves are tender, flavorful, and at peak quality. Plant is ready for cutting or pulling whole. Leaves maintain their delicate texture and mild peppery taste.
Harvest in the morning for best flavor and crispness. Cut outer leaves first for continuous harvest, or cut entire rosette 1 inch above soil for regrowth. Use within a few days for best quality.
Bolting
5-7 days before poor eating qualityPlant begins to flower, sending up a central flower stalk. Leaves become tougher, more bitter, and less desirable. Small yellow flowers appear at stem tips.
Once bolting begins, quality declines. Harvest remaining leaves and replant. In spring, allow some plants to bolt to attract pollinators and save seeds.

Harvest Tips
Mizuna is ready to harvest 30-50 days from planting. Begin harvesting outer leaves once the plant is 6-8 inches tall for continuous picking, which encourages bushier growth. For whole-plant harvest, cut 1 inch above soil level and the plant will often regrow for a second cutting. Morning harvest ensures crispest leaves. Younger, smaller leaves are more tender and milder in flavor; larger outer leaves may be slightly tougher and more peppery. Can be harvested as baby greens at 20-25 days for salad mixes.
