Germination
3-5 daysSeeds sprout within 3-5 days under moist conditions, producing a small radicle and cotyledons
Keep soil moist during this critical period. Maintain temperatures between 50-70°F for best germination. No light is required for germination.
Seedling
3-5 daysFirst true leaves emerge alongside cotyledons; plant stands 0.5-1 inch tall with delicate green foliage
Ensure consistent moisture and provide bright light (4+ hours daily). Thin seedlings if overcrowded. Keep soil cool.
Vegetative Growth
7-14 daysFeathery pinnate leaves develop rapidly; plant reaches 2-4 inches in height with bushy, delicate foliage
Maintain consistent moisture and cool temperatures (55-65°F ideal). Provide bright light. Begin harvesting outer leaves once plant is 2-3 inches tall.
Mature/Harvest-Ready
2-3 weeks from plantingPlant reaches full height of 4-6 inches with dense, fine-textured leaves ready for harvest
Harvest frequently to encourage continued leaf production and prevent bolting. Can be cut as baby greens or harvested as a mature crop.
Bolting
2-3 weeks after maturityIf left unharvested or exposed to warm temperatures, cress will flower with small white or pinkish blossoms and begin to decline in quality
Harvest before bolting occurs for best flavor. Once bolted, leaves become more bitter. Can allow bolting if seed collection is desired.

Harvest Tips
Cress can be harvested as baby greens 10-14 days after planting, when leaves are 1-2 inches tall, or allowed to mature to 4-6 inches (14-21 days). Cut leaves from the outside inward, pinching or snipping with scissors just above the soil line to encourage regrowth. Harvest in the morning for best flavor and crispness. Mature plants can be harvested entirely by cutting at soil level. Cress is best used fresh shortly after harvest.
