Specialty Gardening: Does anyone have the secret to growing petunias ALL summer?, 1 by cindyeo

My petunias in containers are all very scrawny right now, they were beautiful right up until about 2 weeks ago, which is when we finally got some hot weather here in Massachusetts. But I kept them well watered. And I cut them back a bit about 3 weeks ago. But there are no flowers now and they look awful. Everything else in the same pots are doing fine. Is it just a fact of life that petunias peter out? Or is there a secret I'm missing? August 2:
