Possum proof - I hope

We have spent days repairing/cleaning up our garden since the major tree removal work last week. Today I turned my attention to possums. This little garden bed is a favourite of theirs. They ate the last lot of pansies we planted. Just before we were put into lockdown a few days ago we bought some polyanthus and primula seedlings. We planted them today in the possums' restaurant, but this time I built a little enclosure for them. We'll see who wins this round.
