I think most of your gardening content would be welcome there. I myself write about a raptor called Hypersensitivosaurus and I count that as Natural Medicine content, as the group is also very much focused on health and natural healing and creativity plays a part in that.
I would suggest you come hang out with us in Discord. If people get to know you a little better, you will be part of the family - in the least scary meaning of the word possible - very soon.
Let me know if you're interested in joining and I'll sent you an invite.
Have a great day,
Vincent
