worms

Have been doing some garden maintenace, put some manure and soil enricher down about 2 months ago, but still not a worm in sight,have never come across this before,any thoughts ????
Have thought about getting a worm farm, anyone had any success with them.I am in Perth and wondered if anyone has any idea of a good supplier around the Mt Lawley- Bayswater area ???
I was looking for a jarrah hall table earlier, not much luck I'm afraid. There was a lovely one at an auction which I attended, but went close to $1750, but did manage to get a beautiful jarrah wine rack, which looks great in my entrance hall.Now to fill it with some great wines.

cheers
