Why are my petunias sticky?
Petunias emit a gooey material via the tissues of their stems. The sticky stuff, in turn, travels all the way to their soft foliage. The goo is believed to be protection against insect nuisances like thrips and aphids, according to the Utah State University Extension.

Petunias are susceptible to Fusarium, which is a fungus rather than a true disease. The fungus invades the roots, and takes in the water before the petunias can. Just like an under-watered plants, this leads to wilting. You may also see yellowing or browning of the leaves as well.
