Outside my back door I have a dozen pots of various herbs on a gravelled
area. Something is digging in the pot of thyme throwing the compost onto
the gravel. About a third is now out and the roots of the time exposed
almost to the bottom, this has been happening over several days. What is
it likely to be? There is very little moisture there, though there are
odd trails of slugs/snails on the exposed compost. Not worried, just
wondering, mind you it is a bit of a pain as I will have to clean up the
gravel nearby. I intend replanting with a new thyme plant then cover the
compost with mesh. That still does not explain the cause. Any ideas please?
