What causes petunia leaves to turn brown?
I have five petunia double peppermint hanging baskets, They lookd ice but now they are wilting ,the leaves are brown on the edges and even the small leaves are brown . I called the nursery where I bought them and they told me I watered them too much or fertilized too much or I have a bug in tthem . I have only had them about a week and a half. I was talking to another grower of flowers and he told me that you can't over water or over fertilize petunias . I don't know who to believe and I don't know what to do for these plants. I have spent more on these plants than I have ever paid for hanging baskets .And I have had a lot. And it is very depressing. Please Help! Thanks in adavance for your advice.
