Watercress thrives in consistently moist to wet conditions, making it ideal for growing alongside streams, in water gardens, or in containers kept saturated. Provide partial to full sun and keep the roots submerged or the soil soaking wet at all times. Harvest young leaves regularly to encourage fresh, peppery growth and prevent bolting.
