do I need to deadhead supertunia flowers

Question

my hanging plant has supertunia, superbena, goldilocks rock flowers. should I deadhead,

Answer 1

What a chore it would be to dead-head these prolific flowers! Fortunately, it isn't necessary. As stems get leggy or flowering decreases, trim the stems back by 3-5 inches, fertilize lightly (half-dose) and a new flush of blooms will occur. If a stem has no leaves lower down, trim it all the way down.
