Do you cut off dead flowers or leave them?

Question

Recently planted and not sure if dead flowers need to be removed.

Answer 1

Some plants don't need it, like wax begonias. When you buy a plant, the tag might say "self cleaning" and that means you don't have to deadhead. However, when stems get lanky, cut them back several inches to promote bushy growth.
