I have a large potted petunia plant with wave, petunias, geranium and two other creepers in a rather large hanging pot. It bloomed beautifully until rains came and the petunia blossums wilted.
The geranium and other creepers look great. The petunias which drape down about 3 feet are not blooming at all.
Is there a household product that I can add to watering that will help increase blooming?
