Can anyone tell me what is wrong with my zinnias? I bought them and planted them about a week ago and they looked healthy. Over one week the leaves are turning brown and wilting from the bottom up. I don't see any pictures online that they look similar too. What can I do (preferably organically) to help them? I have always had zinnias and never had any problems whatsoever, which is one of the reasons I love them!

Thanks
