|We have 3 grape vines, how tall should they be and do we have to do anything special with them?
They are purple grapes, do not know what species.
|Because you're new to growing grapes, let me share a wonderful source of information through Washington State University. Here's the web address: http://mtvernon.wsu.edu/frt_ho... You'll want to download and read the publication EB0775, Growing Grapes. I promise you that this publication will address all of your concerns and help you grow productive grapevines.|
