  • The next step is very simple: just remove the lower leaves from the sprouts and place the sprouts in the water to develop roots.
  • After one or two days, you will see the roots start emerging from the sprouts. You can also place the water jar on a seed germination mat to provide warmth. Make sure your sprouts get enough light so the roots will develop quickly.
  • Maintain the water level in the jar, it should be high.  Freshwater is very important, keep changing the water. If you see wilted or rotten slips then discard them.
  • When the roots are fully grown and several inches long then it is time to plant them in the soil of the container. The height of the slip should be 12 to 18 inches long then plant them.
