Wormery?

I use a wormery and have found that, as Proserpina has said you get better results when you add cardboard /paper into the mix, using kitchen waste usually adds a lot of moisture, which is collected as worm juice, but some people think to get the best compost from your worms there should be no or very little juice from the wormery, to get that you need something bigger than the usual size, tiered wormeries that are on sale, the advice is also to avoid onions and citrus fruit skins as the worms don't like material like that, I do think it gives better compost and as t.t.t has said it is also believed that it helps keep plants healthier
