We have a hibiscus in a pot on the window sill and masses of powdery soil
is regularly appearing in the saucer coming out from the bottom of the
pot.

We are assuming it's a worm? Is it detrimental to the plant in any way
and should it be fished out? One curious aspect is that its pushing out
so many of the little soil granules that the pot no longer even sits
upright.... that's a lot of serious pushing out.
Seen any ants about?
