Growing Organic Watercress

Start watercress indoors or sow directly outdoors during suitable cool-season conditions.

Sow seeds approximately 1/4 inch deep in rich, moist growing medium. Keep the seedbed consistently wet throughout germination.

Under favorable conditions, germination commonly occurs in approximately 7-14 days.

Watercress thrives when the root zone stays saturated with clean water. Avoid allowing the growing medium to dry completely.

Container Growing

Watercress is well suited to pots and containers because its moisture requirements can be managed easily.

Use a container with suitable growing medium and place it in a shallow reservoir of clean water to maintain wet conditions. Refresh the water regularly.

Seedlings can initially be grown closely together and thinned to approximately 4 inches apart as needed.

Hydroponic Growing

Watercress can also be grown in suitable hydroponic systems with clean water, appropriate nutrient management, cool temperatures, and adequate light.

Use a controlled system and follow appropriate food-safety practices when growing leafy greens for consumption.

Sunlight and Temperature

Watercress prefers cool conditions, approximately 50-60 F, and thrives in bright light or partial shade.

In cooler weather it can grow in full sun when adequate moisture is available. During warmer weather, partial shade helps reduce heat stress.

Harvesting Watercress

Watercress generally reaches maturity in approximately 50-60 days under suitable conditions.

Harvest the tender young leaves and crisp stems before flowering, when the flavor and texture are most desirable.

Use clean scissors to cut stems above the growing medium.

For continued production, avoid cutting away more than approximately one-third of the plant at a time.

Culinary Uses

Water Quality and Responsible Growing

Grow edible watercress with clean water and controlled growing conditions. Avoid using potentially contaminated natural waterways or livestock runoff.

Watercress can spread in wet environments. Keep cultivated plants contained and do not release them into streams, ponds, or wetlands.
