Hi there ! It depends on your goal ! If you don't need to go stealth then just a little lst with stem bending will be enough , you can top some of the stems to double them but outside I personnaly prefer to let them thrive by they own from the begining to the end of the grow. And by the way , if you have a garden the plant her in the garden rather than in pot , make a big hole and fill it with good soil ( all mix ) and some guano or lombricopost to make a kind of "super soil" ( kind of) ! Hope it will help you 😁👍
