Yea, that's kind of where you are stuck. Between a rock and a hard place. If you see fast growth going forward then you maybe should try to leave it but cooler weather is coming and they don't like that. I can not imagine it recovering over winter. Maybe I am wrong but I have killed several over many years and have another I bought this year that is potted and it has pushed about a leaf a week except for when I moved it to a larger pot and it skipped one week. I am thinking the soil is wrong or there is an underground pest problem. The last one I put in soil went from the size of yours in May to a giant over summer with 3 babies by October but was in a lot of sun. By the way judging from my past experience I fully expect to lose mine someday.
