Aubergine

I am trying Aubergines for the first time and have 5 going strong ,I read on another site that when 5" high pinch out the growing tip and encourage 2 leader shoots, and only let 4 fruits per plant ripen.

How tall and wide are these going to grow I can`t find that info ,and any other tips

 

I don't pinch mine out, as they bush up naturally. If you pinch them out it takes 2 or 3 weeks for them to get back to where they were (but you will need to do that if they don't bush out naturally).

Mine grow a bit more than knee high, and a couple of feet across.
