The secret of growing watercress is to keep it in full sun and the soil damp, but make sure it's never saturated, since overwatering can kill your crop. Never pick wild watercress — it may contain a waterborne parasite called a liver fluke.

Materials Needed:

  • recycled plastic bottle
  • store-bought watercress shoots
  • potting soil
  • recycled container

1. Place long shoots of watercress into a container of water.

You may use store-bought watercress for this method of growing the plant.

2. Allow time for seedlings to develop roots.

Watercress will grow in full sun. As they roots flourish, new shoots will begin to grow.

3. Repot into moist potting soil.

Once watercress seedlings have developed an abundance of roots, they are ready to be transferred to a container.
