Funny you should ask it started life in a bigger pot but took off really slow (I probably stunted it somehow). And as I don't like to waste rather than killing it I just stuck it in the smallest pot I could find as a bit of an experiment. I then potted another (blackberry gum) in the larger pot. All in all it wasn't really any faster than the one in the larger pot (20 litres) once it got going. Sorry I couldn't be more precise but you know when you have been doing it this long you kind of give up counting the days haha all in all expect them to take just as long as those in bigger pots.
