I was so happy to see the folks from Yelm Earth at the Seattle garden show. This worm farm in Washington state has been through a lot of changes over the years. I went to visit it when I was doing research for The Earth Moved and I think it was for sale then. Anyway, there’s a good group of people tending the worms, selling castings, and more. They’ve got a rich supply of manure for feedstock, good equipment, and plenty of knowledge. Check them out.
