Thanks for the input, Mitchell. I actually noticed maybe 2 months ago that it was sending out two shoots. (Man, they get stiff really fast.) They were unfortunately, though probably not surprisingly, at the top, which is where I don't want new growth. As such, I pruned off the top section to try to force it to send any growth energy to other locations where I need more branching. We'll see if it responds.
To answer more directly some of your points:
- My latitude is just a little south of yours.
- In the summer, it is outside with nearly full sun, but it's not usually more than around 80ºF/27ºC. So I don't know if that could be affecting it.
- Once it starts cooling off notably overnight in the autumn, it comes indoors for the winter. It sits on a table next to a south-facing window, so it gets maybe 4 hours of sun there.
- In the summer, outdoor humidity is pretty much always over 50% here. It sits on a humidity tray inside.
- I don't think those woody nubs were shoots. I think they're just like a callus/build-up from the tree putting out leaves in the same spot without branches. They seem to get larger without any shoots.
- I'm no expert, but I think the colour of the leaves is good. A couple will get pale and fall off here and there, but they're a rich green for the most part.
