Q.Dying petunia plants
I planted petunias in a pot in June and they have been thriving. A few days ago 1 plant started dying, now I have 2 more plants dying. They are not being over or underwatered. I have not seen any bugs on the plants. I am wondering why they have been doing well for 6 weeks and then all of sudden are dying.

They are annuals, most of them, and will die off once they are done, though it is a bit early. Unfortunately, without seeing the plant in question, I can only assume what is going on.
The most common issue for these flowers is overwatering, and getting water on the leaves and flowers. Both will cause a sudden death out of no where sometimes.
Next will be too much sun. They will flower profusely in full sun, then wither out from exhaustion.
Disease will be common, too , but there are many of them and to diagnose them would be to see them.
