That is my exact experience. The worm castings are very dense and claylike.

My red wigglers survived the winter in a cold garage, on a diet of mostly coffee grounds and shredded newspaper. And the occasional banana peel. I was expecting the end result to be crumbly - like good, humus-rich soil; but instead I find the castings to be rather sticky, like clay. There are no "off" smells that I can detect - I don't think it went anaerobic. Is this a cause for concern? Did I not harvest soon enough? Thanks in advance for any input.
