About 3 months ago, I noticed a small protusion on the trunk of my ficus. It looked like a root so I let it be. Indeed, it was a root growing further up the trunk. I’m putting it down to the fact I was using Rhizotonic on some of my plants and decided to — for reasons yet known to me — add some to my bonsai on a couple of waterings.
As you can see, it has grown a fair bit. I thought it would have fallen off by now. It has dried out quite a bit, but I might just let it fall naturally rather than cut it off.
(Excuse the white crust of water residue, haven’t cleaned this off yet).
