Alternatively, put some sheets of damp cardboard on bare soil under the
shrubs for a day or two, then gather the thin red worms from under that.
I seem to recall that if your compost smells really strongly ammoniacal
it's probably too acid for them (and the better bacteria, too); fork in
a few good handfuls of garden lime to aerate the stuff and alter the pH.

That's a good idea, I'll give it a try tonight

Thanks
