Q.Should my plant grow vertically?
I’ve had this plant since 2016. It keeps growing straight up. In 2018, it drooped over so I placed sticks in the soil to keep it from drooping. Was that the right or wrong thing to do?
It has a new branch coming from each main branch. Can I cut the new ones off and start a new pot? Will I harm the plant?
I really just do not know what to do with the plant anymore as the vertical growth doesn’t seem sustainable. Any advice would be appreciated!

New and established peperomia plants benefit from annual light pruning to correct any leggy, sparse growth. Pinching back the stems in early spring will help by encouraging more branching. Remove the end of each stem and the first set of leaves, pinching them off between your fingernails.
