If the plant flowers, that means it's root bound. After the flowers die off, should I repot plant?
How wonderful that you have a flower! I have grown this houseplant for years and never seen a blossom.
It can indicate that your plant is pot bound. I would wait until the flower fades and then you can repot the plant into a slightly larger pot.
Only go 1 or 2 inches larger in size.
You also can divide the plant if the size is getting to large for your liking.
