Superior neglect of a 30 year old Fukien Tea

I have a Fukien Tea in an approx. 8-10" diameter and 3" deep pot. The tree has been healthy with plenty of growth and blooms. The tree has not been repotted in over 12 years time and yet it continues to look healthy.

First - is this normal for a Fukien Tea. That is to be in a small pot for so long without major problems?

Second - Since we are past early spring (Oregon Zone 8a) can the tree still take a repotting?

Third - are there any special instructions when repotting after such a long period of time?

Cheers

as it has been in this pot for 12 years.. Wait till spring.

I think it is fairly long.

Fair point !?!
