Even though I deadhead my petunias, by pinching out the spent flowers, my plants still get very leggy. How can I have fuller and prettier petunias?
How to Have Fuller Petunias?

This is standard petunia behavior, especially in warmer weather. You can give them a bit of a haircut though. Try cutting about a third of the legs back by half. When new growth begins, cut another third and so on. This should rejuvenate the looks of your petunias and encourage a bushy growth rather than a leggy one.
