Growth Stages

1

Germination

3-5 days

Tiny seedlings emerge with cotyledons (seed leaves) visible within 3-5 days

Keep soil moist and provide light as soon as sprouts appear. Maintain temperatures between 60-70°F for best germination.

2

Seedling

5-7 days

First true leaves begin to appear; plants develop their characteristic moss-like curled texture

Ensure adequate light to prevent leggy growth. Keep humidity moderate and continue consistent watering.

3

Microgreen/Young Growth

7-10 days

Plants reach 1-2 inches tall with fully formed cotyledons and emerging true leaves showing curled texture

Provide bright indirect light. This is the optimal stage for microgreen harvesting for maximum tenderness and flavor.

4

Vegetative Growth

10-15 days

Bushy growth with multiple stems and increasingly curled, finely textured leaves; plant reaches full height

Thin seedlings if direct sowing. Water consistently and provide good air circulation to prevent fungal issues.

5

Harvest Readiness

Harvest-ready at 2-3 weeks

Plants are 4-6 inches tall with dense, mature, deeply curled moss-like foliage at peak flavor and tenderness

Begin harvesting when leaves are fully formed. The longer cress grows, the more peppery the flavor becomes.
