1. When making a salad or food with one of these vegetables, cut off an inch length from the base and save them for later.
  2. Place the stubs in a container with water, make sure that the stub is not submerged in water but very close to the top (roots facing down).
  3. Place the container on the windowsill, or anywhere with plenty of sunlight, and make sure to refresh the water regularly.
  4. Once the roots reach a formidable and healthy size, relative to the stub, and some green stats poking out of the stub, transfer the stub into soil so that the top of the stub is level with the soil and water the plant regularly.
  5. Harvest the plant by just cutting off the greens.
