I can't seem to find an answer already to this, but do any bonsai principles apply to an herby plant like a gerbera daisy?

I have a g. daisy that is almost 2 years old that just keeps sending out flowers and refusing to die. I potted it into 1:1:1 and it sucks the water out of it every 2 days.

Its leaves and flowers are too long for the smaller pot that it's in and it doesn't look great.

I'd like to have it grow more compactly.

Can I root prune and defoliate it a bit to encourage smaller growth?
