Worms don’t provide eggs or fleece or any of the other things one thinks of when considering livestock but they are still a valuable resource. And they produce material that will give any garden or flower bed a kick in the pants.
If you are a gardener, large or small, I would HIGHLY recommend that you have a copy of Seed to Seed on your bookshelf. There’s a lot of satisfaction in breaking yourself from having to buy seeds every year. And this is just the resource you need to get started.
