I have a large unplanted pot which still had a lot of potting mix in it. I
decided to combine it into another pot. When I was tipping it I saw masses
of red worms and at least half a dozen large witchetty grubs. Are these
useful or harmful in a pot? Should I try to remove the grubs or just let
them be. I will probably plant a citrus or other small fruit tree in this
pot (which is quite large).

Best practice seems to be to get rid of the grubs, otherwise they are
likely to chew on the tender new roots of anything you grow since there
is nothing else in there for them to chew on. As for the worms, they
will probably move out anyway.
