I have a large ycca (I think) that has always had 2 trunks. Over the last few years it’s grown more trunks and now seems to be sprouting new trunks all the time! Now it has loads of trunks It doesn’t seem so healthy and is constantly dropping leaves. My question is should I be thinning it out?

Yes, sometimes it is necessary to dig the plant up, and replant only a few tubers or just one well rooted plant. I think it is getting overcrowded and is outcompeting its self.
