4 and 5 were eaten. Number 2 had a spare which was donated to 5. The culprits were identified as slugs and snails, so preventative measures have been taken. The clear plastic bottle guards were upgraded and spikes added to the tops, ash and crushed egg shells surround each plant and there is a milk/beer trap.

Something seems to have eaten some of the seedlings, cut clean through the stems. So I have erected guards made of clear plastic bottles around them.
