I have a very large trailing petunia growing in a container on my deck. It gets plenty of sun but also shade part of the day. The flowers are fine, but the vines look like they are wilting and separating. It's starting to look very long and straggly. I water it and give it Miracle Gro. It has been quite windy and rainy but the plant is protected pretty well. Hope you can help, as I don't want these beautiful plants to die.

Many annuals begin to get a little leggy this time of year. 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.
