Seedling
1-2 weeksTiny cotyledons emerge 3-5 days after planting. First true leaves develop within 1-2 weeks, showing the characteristic frilly structure beginning to form.
Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy seedlings. Thin seedlings to proper spacing once they have 2-3 true leaves.
Early Growth
2-3 weeksSeedlings establish true leaves with increasingly pronounced feathery, frilly margins. Rosette begins forming as multiple leaves develop from the central stem.
Continue consistent watering and moisture. Begin light fertilization with balanced or nitrogen-rich fertilizer every 10-14 days. Mulch lightly around plants to retain moisture.
Vegetative Development
2-3 weeksThe plant develops a full, bushy rosette with many deeply dissected, lacy green leaves. The ornamental, frilly appearance becomes fully evident. Plant reaches 8-12 inches in height.
Maintain consistent moisture and cool temperatures. Continue regular fertilization. Monitor for pests, particularly flea beetles and aphids. Avoid overhead watering to prevent fungal issues.
Mature/Harvest Ready
Ongoing until boltingLeaves are fully developed, tender, and abundant. The rosette is full and visually striking with its intricate, feathery foliage. Plants are ready for harvest at 4-6 weeks from planting.
Begin harvesting outer leaves as needed. If temperatures begin to warm or approach bolting, accelerate harvest. Maintain soil moisture to prevent bitterness and bolting.
Bolting/End of Season
Variable, triggers with heat and photoperiodFlower stalks begin to emerge from the center of the rosette. Leaves become tougher and more bitter in flavor. Plant prepares for seed production.
Harvest all remaining leaves before bolting is complete. In warmer seasons, plan for succession planting in fall. Remove bolted plants to avoid self-seeding.

Harvest Tips
Mizuna can be harvested at baby leaf stage (4-5 weeks) for tender microgreens or allowed to mature fully (6-8 weeks) for larger leaves. Use the cut-and-come-again method: harvest outer leaves from the bottom of the rosette as needed, allowing the center to continue growing. Harvest in early morning for best flavor and texture. Entire rosette can be cut at soil level for full harvest. Mizuna is most tender and flavorful when grown in cool weather; harvest before temperatures exceed 75°F to avoid bitterness.
