Propogation by seed
From Early Spring TO Early Summer
Sow the watercress seeds, planting two or three and evenly spacing them apart from each other. For the best results, bury them approximately 1/4 inch below the soil surface. The seeds typically germinate within five days. Amend the garden loam by mixing 6 inches of compost into the top 8 inches of soil. Watercress thrives in soil with high levels of decomposing organic matter.
Planting young plants
From Early Spring TO Early Summer
Fill a gallon-sized pot with standard garden loam. The pot must have drainage holes at the bottom. Amend the garden loam by mixing 6 inches of compost into the top 8 inches of soil. Watercress thrives in soil with high levels of decomposing organic matter. Plant seedlings at least 3cm apart and water regularly.
