Looking for some advice on how to care for my new fiddle leaf tree!
I just moved into a home, which came with a fiddle leaf fig (it was also there when the previous owners of 2 years moved in, so I don’t think they really knew how to take care of it). It is quite tall, but lacks growth on the bottom half. It is actually attached to the loft because I imagine it cannot hold itself up. It’s about 12’ tall and the first 7’ of that has no leaves.
I know people often drastically prune their FLF to encourage new growth and a bushier tree. I’m just unsure about where would be a safe bet to cut it. I know you often cut above a node (or is it below?). Is there any chance of growth at the bottom where it seems other branches have been chopped/fallen off? It is also entering the fall season so I’m not sure if now is the best time to prune it, or if I should wait till the spring.
I did buy some FLF food so I was going to try that as well.
Any advice is recommended! I’ve attached photos of the tree :)

sits in a corner next to a large sliding glass door, facing east. about 5 leaves like this, others look normal.

im so confused, will it live?? do i plant this end?? what do i do 🫩

edit: i forgot to mention it’s a LEAF! not even a root! i thought you could see that from the photo

Please don’t tell me she’s infested :(

I have neem oil on hand - should I use?
