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).
