A florist friend of mine uses 25cm cinnamon sticks for flower arrangements. They typically have a profile like a slightly open B-shape and are extremely sturdy. When I saw them, I immediately thought these may be great to grow on smaller mounted orchids. Of course cinnamon also has anti-fungal and anti-bacterial properties and should not break down easily. I was wondering whether anybody has experimented with cinnamon sticks as growing medium for smaller mounted orchids and seedlings.
I would think the same as above. While it's great for treating cuts I've always heard you should be really sparing with it on roots as it dries them up a lot.
Cinnamon (by way of it's essential oil, Cinnamaldehyde) is a dessicant, so yes, it would be counterintuitive to use it as a potting media. It's dessicating/drying properties are what make it such a good antifungal and wound sealer though.
