Germination
3-5 daysTiny cotyledons (seed leaves) emerge within 3-5 days; seedlings appear delicate and pale green
Keep soil moist; provide gentle indirect light; maintain temperature between 50-70°F for best germination
Seedling
5-7 daysFirst true leaves begin to unfold; plants develop their characteristic deeply lobed, curly leaf structure; growth accelerates
Ensure adequate light to prevent leggy growth; thin seedlings if overcrowded; maintain consistent moisture
Vegetative Growth
7-14 daysPlants develop multiple sets of delicate, frilly leaves; foliage becomes denser and more ornamental; peppery aroma becomes noticeable
Water regularly; can be harvested at this stage for microgreens; provide good air circulation to prevent mold
Full Maturity
5-7 daysPlants reach full bushy growth with abundant curled foliage; flavor is most concentrated and peppery
Begin harvesting outer leaves; keep harvesting to encourage further production; plant begins to bolt if temperatures rise above 75°F
Bolting
7+ daysPlants send up flowering stems with small white or pale pink flowers; leaves become tougher and more bitter as plant focuses energy on reproduction
Harvest immediately if planning to use leaves; allow some plants to bolt for seed collection if desired

Harvest Tips
Harvest microgreens at 1-2 inches tall (7-14 days) by cutting above the soil line with scissors. For full-sized plants, begin harvesting outer leaves once plants are 4-6 inches tall, which encourages new growth. Harvest in the morning when flavor is most concentrated. Cress is best used fresh and can be harvested multiple times before bolting
