angel wing begonia plant indoors

Question

Have just brought it in house after a good blooming all summer. It is leggy and sparse. Fed it today for the first time. Can I cut it back or pinch it to shape it?

Answer 1

You should allow the plant to go into a dormancy period.
Very little watering and a cool, dark and dry location.
Don't fertilize during this period.
