This is my first post here so I'm sorry if my questions were asked and answered before, but I wasn't able to find those posts. I ordered some Concord vines from a local nursery, but I haven't received them yet. This will be my first attempt at growing my own grapes. My wife and I are planning on trying to sell our home in a few years, so I want to try and grow them in pots for a couple years. I've been able to find some info on growing potted grape vines on this forum and on other websites, but there are a couple of questions I haven't been able to find answers to. The most important is that I am completely unsure on what to do with the plants in winter. A website that let you search by ZIP code told me that where I live is a hardiness zone 5B. Winters can be very frigid here with temperatures dropping to around zero degrees F for days at a time. I have a potted rose bush that I place in my unheated, unattached garage at the beginning of every winter. I'm not exactly sure what the temperature in there is, but the plant goes completely dormant until I bring it out in the early spring. Would this be acceptable for the grape pots? What is the acceptable tempurature range for them in winter? And when should I be putting them in the garage and bringing them out from it? This next one may be a stupid question, but does the amount of sunlight they receive in winter matter? Also, I am unsure on what size pot to use and how tall of something to climb on to give each plant. Any advice anyone can give me on these questions is greatly appreciated.
