Grow it Again!

Turn a sweet potato into a beautiful houseplant. It's cheap, simple and fun!


  • 1 sweet potato
  • 1 glass jar
  • enough stones to almost fill your jar
  • a small paring knife 


  1. Place the stones in your jar.
  2. Fill the jar with water to just cover the stones.
  3. Find a sweet potato that is already growing some roots or buds. If your potato hasn’t sprouted yet, leave it in a sunny place for a few days. You will see little “eyes” start to grow.
  4. Cut a 5 cm piece from the rounded end of the sweet potato.
  5. Place the sweet potato, cut side down, in the jar.
  6. Keep your sweet potato in a sunny place.
  7. Make sure the bottom of the sweet potato is always under water.

Watch it grow

  1. After a week, you should start to see roots growing and leaves forming. If nothing is happening, try using an organic sweet potato.
  2. You can also do this same activity with a turnip, cutting a 2cm slice from the leafy end.
