21 inch hanging petunia plant
Hanging petunia plant that I bought has been shriveled and brown and yellow looking right from the beginning. Now it has gone 1/2 down all leaves are brown or yellow, but the bottom is green and blossoming despite watering it twice daily. I believe it needed a bigger plant pot maybe. I fear it will die.

It sounds like it may have a fungus. Trim away any yellow or brown growth and then treat the plant with a fungicide.
