Watercress is a perennial that grows partially submerged in running water and flooded areas. Watercress grows well in moderately cool climates, and if you have a water feature in your landscape, this is a great place to cultivate watercress. But if not, watercress can also be grown well in consistently wet soil in full sun.
Growing Watercress in 4 Easy Steps
# 1 | Choose a sunny location, and amend the soil with 4-6 inches of composted organic matter. Dig out a 6 inch furrow, and line it with composted soil or peat moss.
#2 | This plant germinates the best in cool conditions (50-60 degrees fahrenheiht) so sow the seeds three weeks before the frost-free date for your area. Keep the planting area moist, but not covered with water.
#3 | Seedlings will appear in about five days.
#4 | Consistent moisture is the number one concern in the care of watercress, so keep the soil most as often as possible.
