I picked up this Cptn Cook at a local nursery at its closing down sale a few months ago for just $5....bargain

It was horribly pot bound so I took nearly 70% of the roots before repotting about 10 weeks ago.
It looks like it is starting to bud so I have 2 questions.
When to chop?
Where to chop?
I'd appreciate any advice on this and styling
Thanks,
Glenn
