Grape vines that won't blossom
I live in Wolverine, MI which is considered a Zone 2. We have very sandy, acidic soil. I've had grape vines: (1) seeded concord, (7) unseeded concord for 10 years. Full sun on the grape arbor. They produce beautiful vines and leaves. What do I need to do to make them blossom? It's been 10 years and never a single blossom. I asked the Minnesota extension (didn't know MI has one) and they said it was probably "non-fruiting grape stock". I purchased them through a MI catalog company, so I don't think that would be the case. Please help me before the grapevines go to the compost pit.
Thank you so much, you sent a picture similar to what I see every spring. I checked back into my garden journal to confirm what I saw with the picture you sent. What you described is probably what's happening. My primary buds are freezing during winter, that makes perfect sense. My grapes start putting forth the secondary buds about the end of April or beginning of May. Then along comes the last frost of the season (usually the last week of May rarely into June) and all I'm left with are the tertiary buds. I am going to buy some straw this weekend and lay some shoots on the ground. I would love to give you an update in the spring. It's already getting into the 40's at night up here right now, but I should have time to get them going before the first frost. Again, I am so grateful for your response. Sincerely, Mary Ford
