Hi Dave,
I am a little late to the party, but wanted to let you know I listened and enjoyed your podcast with Diego Footer on permaculture voices. It is funny that my Comfrey experiences are just opposite from Buttonwillow. I am here in the Northwest portion of Oregon and my Comfrey does the very best where it gets the most sun. Geoff Lawton posted a link about Comfrey on his facebook page that I thought was very interesting. I would have reposted the link here but I don’t know how
I also enjoyed you talking about Yarrow. That has encouraged me to seek some out for my property. And I have been formulating a plan for my chicken habitat very similar to what you have described. Thanks again for a wonderful podcast. I know I had a couple questions right after I listened, but darn if I can’t remember what they were
