wait for flowering to end ....let flowers fall away freely .... then allow about a week to pass to see if any seed pods form at the ends of stems ...
to make your cutting "less Lanky" and encourage the stem to be thicker, more "trunk like" ....cut current stem just above where it starts to bend
this new cut will force 1 to 5 new stems to emerge ...... you want as many new stems to make it, as flower buds form at the ends of stem tips
as new stems emerge, pinch out leaves that shade out, or crowd other leaves
I would repeat the cutting (cut the top off) once every 2-3 years
