Depends on many things, light scource is number 1, sun best imo. If really trying to save plant, first if photo ld repot and rootprune, or at least break roots up, if any to speak of, then id find the biggest pot l can. Feed a high phos nute and grow some roots. The top will take care of itself. Just my opinion. I have a garden too.lol. powdered are cheaper as not paying for water. Best example l can give is 10-52-10 half strength at first after they show signs of recovering feed veg nute. Just my opinion, not bashing op. If auto id repot but not disturb roots if possible.
