Hello there. I am not an expert gardener. I am trying to plant some geraniums in outside pots and a flower box. The plants that I bought were very, very healthy and beautiful. Unfortunately it was a bit cold up here in good old Wisconsin so I didn't plant them right away. I have since replanted them. The leaves look healthy but the flowering part is dried and dying. How do I bring them back to life? They do look like they are starting new buds. When I remove the old flowers do I pull the whole flower "head" out or do I just remove the dried petals. I really would like to salvage these plants if possible.
