Germination
2-3 daysTiny seeds sprout and develop cotyledons (seed leaves) visible within 2-3 days
Keep soil moist and warm (60-70°F). Ensure good light exposure immediately upon sprouting.
Seedling
3-5 daysSmall green seedlings with 2-4 true leaves, very delicate appearance
Maintain consistent moisture and provide adequate light to prevent leggy growth. Thin seedlings if necessary.
Vegetative Growth
5-10 daysRapid development of compound leaves on thin stems; plant becomes bushier
Continue regular watering and ensure good air circulation. Can begin harvesting outer leaves at this stage for microgreens.
Mature Foliage
Ongoing after 10-14 daysFull, feathery foliage with vibrant green color and peppery aroma; plant reaches 6-12 inches tall
Begin harvesting by pinching or cutting outer leaves. This encourages more growth.
Bolting (Optional)
2-3 weeks after mature stagePlant sends up flower stalks with small white or pinkish flowers if left unharvested
In warm weather, bolting occurs quickly and signals declining leaf quality. Harvest before bolting or allow to set seed.

Harvest Tips
Harvest as microgreens 7-10 days after sowing by cutting just above soil level. For mature plants, begin pinching or cutting outer leaves once plant has 4-6 true leaves (around day 10-14), and continue harvesting to encourage bushier growth. Best flavor and texture before bolting occurs. Can be harvested multiple times from the same plant over 2-3 weeks.
