It has never flowered - is it supposed to?

I never know how much water to give it - it only seems to grow after i've watered it.

I only water it between say mid March to mid October - is this ok?

It seems to produce new branches but the original trunk has stopped growing and the branches are now actually taller. Is this normal?

Thanks for any replies.
