I have a question,i have a huge wavy petunia.I should say was huge thats dying on me.Flowers are turning brown,i think i overwatered it but i'm not sure.I thought the chilly nites got it but i see others that left there flowers out and look great. Thought about calling the florists that i bought it from.My question is will it recover? I'm sick over it this plant was huge now it looks awful,it still has some flowers.
