I know this sounds a bit simple, but I am in charge of our plants at a retail store. I have a question about when to deadhead geraniums to maximize their looks. I'm an avid gardener, but what I'd deadhead might be different from what someone in a retail setting might.
When do y'all consider a bloom head a deadhead candidate? When a stem's flowers are 50% spent, 70%, or whatever?
I'd love to hear how y'all decide when they bloom head stays and when it goes.
