If you can’t see why it’s a good idea to put a plank of wood like this in one’s garden water butt, you’ve clearly never had to get the drowned corpse of an indeterminate creature out of one, as we once did. Anyway, over the last few months, it has been colonised. The slime came first — now, this rather more photogenic red fungus, or that is what I assume it is. Who knows, give it a couple of thousand years and we might have entire civilisations existing in this water butt universe.
