Older leaves will yellow and fall off. It looks healthy, but I'm not sure it's a Singapore (hopefully someone with experience will chime in).

jacobean - that definitely is not singapore. Singapore has glossy leaves and rounded tips and doesn't have red petioles. I think I see red veining in the leaves, too?

It's normal for the leaves to yellow and fall off..

I would worry if I saw bugs and all of the leaves were yellowing at the same time. It's doing what it is supposed to when it grows, Natural shedding !!!

Have fun!!

Thanks for the help. I will go ahead and repot now. I just thought that the leaves were suppose to stay on longer.

There is red veining in the leaves. So, I won't be surprised when the leaves fall off in winter because its not a singapore.
