Hello, we planted grapes this spring - some have done well and some haven't seemed to grow at all above ground. The problem now is that I'm not sure which grapes are which as I was not home when they were planted and my husband doesn't remember. So, I was wondering if you can distinguish grapes by their leaves? I have three varieties: Himrod Seedless Green, Blue Concord, and red variety that I haven't found the packaging for yet. My grapes actually have a one year warranty if they do not grow so I wanted to call so any help would be appreciated. Thanks!
