I have planted many petunias around my home. Most of them are doing very well but one section I have planted are not bushing out, just growing straight up with only one stem and the leaves do not seem as green as the others. These plants were all purchased at the same time. Can you please tell me why? Thank you.

Heat, lack of water, lack of light and age can all cause leggy petunias like this. Make sure they are getting enough water and light and prune them back by about 1/3. This will force them to branch and will rejuvenate them if age is to blame.
