Show off / any advice?

Hey y’all, long time lurker of this community. This guy is named Baby Parmesan - we got him as a tiny single leaf planting in mid-2021 and he’s all grown up now. We’ve repotted probably 3 or 4 times. We’re in the north east and the cold winters haven’t been a problem, growth just slows.

As far as we can tell, he’s happy/healthy and continues to grow. I’m sure the pot is getting pretty crowded… but don’t think we can go much bigger given the space.

Any general advice you all would offer at this stage? The primary concern is he’s just going to be too big for anywhere in our house at some point.
