Good for you!
Worms are a gardener's best friend!

It's probably too late in the year for worms-
you'll likely have some good worms in your compost by late spring.

Meanwhile, gardenweb has 2 other forums you might want to visit:

Soil Compost & Mulch and
Vermicomposting

Have fun!

Worms love sweets! Pumpkin, apples, bananas. If you are serious about starting up with some worms, find someone with horses and ask them if you can dig some from their manure piles. They are free and will do wonders for your garden!

Worms do love manure, but make sure that it is seasoned so it won't heat up and kill them. They also love newspaper, cardboard, veggie trimmings. I am patiently waiting for them to establish themselves in my extremely sandy yard, but nothing has happened yet. I figure it's the dead of winter now and that is having something to do with it, and surely by spring there should be some signs. I have spread newspapers and cardboard over the yard and in some places I have put little pockets of compostibles. I have an inside vermicomposting bin and I have even taken a few of the cocoons from there and buried them in places around the yard under the newspaper mulch. (I wouldn't suggest putting actual worms out there because I think that it would be a shock to them and they wouldn't survive the change). The worm cocoons have a much better chance to adapt to the environment they are put in than actual live worms. When it starts get warmer where you live try and get some cocoons to put in your yard.

ps I used to get loads of worms in the composted steer manure that I would get at the hardware store
