This orange tree recently came into my care. It's been around for a decade or something. Do you know if it's desperate for a bigger pot?
It seems to have some issues with its leaves: the newer leaves are curly, and some other leaves have brown spots. I'm looking these things up right now, but if you recognize them feel free to let me know what they are.
