Cress Porcupine You will need:

  • A small plastic drinking bottle (square rather than round)
  • Googly eyes
  • Kitchen paper
  • Cress seeds
  • Water
  • Cling film/Saran wrap

How to grow a Cress Porcupine

  • Lay the plastic bottle on it’s side and cut out the top side of it. Keep the plastic near the front of the bottle opening in tact.
  • Stick some googly eyes on near the bottle opening.
  • Take 5 pieces of kitchen paper and place them on top of one another.
  • Fold the paper in half and then half again.
  • Run the paper under running water quickly and on both sides. It should be wet but not dripping.
  • Place the wet kitchen paper inside the bottle. You might have to cut the end of it off for it to fit.
  • Sprinkle a thin layer of cress seeds over the wet paper – make sure they are evenly spread.
  • Cover the bottle in cling film/Saran wrap so the seeds are sealed in. We’re creating a greenhouse effect.
  • Put the Cress Porcupine in a dark, warm place until the shoots are 1cm tall.
  • Then move it to a windowsill. The cress will be ready to eat in 12 days maximum from when you first plant it.

Tips for growing cress

If you only have a round bottle, steady it by putting four pieces of plasticine at the bottom. These can be made to look like feet.

Keep a close eye on your cress. You need to check on it every day and make sure the kitchen paper is always wet.
