Earthworms ;o) and grubs :(
I'm pulling out old plants from big tubs and there must be hundreds of earthworms in one, also lots in another. However, in the one replete with fat, happy worms are also big, fat, shiny grubs. I think I got them all but I can't be sure. I don't want to dump all the dirt and lose the worms. What would you do? And do you think the grubs will return?
