Hey David (and David the Good),
I live in a cold climate with a small plot same as you. I haven't heard of bokashi before. Thank you for bringing this interesting tidbit to my attention. We don't drink cow's milk but we do enjoy cheese. Mmmmmmm. I'll talk to the Miss about that.
What are your thoughts on composting on ground under heavy mulch? Ruth Stout talks about it in her book, Gardening Without Work. I have a herb garden I was thinking about a heavy straw mulch and throwing extra what I don't throw to my Red Wiggler worms. Would the earthworms in the ground process the stuff if you have a good environment for bacteria?
I hope David the Good has something to add to this. But if you just want to say get your book. I'll all about it.
