Replacing my grapes-need info and advice
I don't know how I killed off my grapes. They were in pots buried up to the soil line (waiting for me to get a trellis up) until mid May. After I dug them up we did have one more cold and snowy spell, but not much below freezing. These were all grafted grapevines: Marquette, Himrod, Marquis, and Remaily.
I would like advice as to whether these cultivars are really hardy here in zone 5. Maybe it was just the crazy spring that did them in?
I recently bought a St. Theresa at a local nursery. While I was there they also had another Swenson grape called Trollhaugen. I was wondering if anyone has experience with Trollhaugen. I would also like opinions on Einset in comparison to the ones I had purchased.
Should I just replace the ones I lost or choose new cultivars?
