Description : Should I "deadhead" my petunias to make them bushy, and to keep them from getting "leggy" ?
Last Answer : Yes, it is good to deadhead and even remove most of the long branches that develop on petunia plants over the summer. At about the first of July cut back half of the branches on a plant and fertilize. ... . By August they will all be growing well and looking as good as at the first of the summer.
