The best advice I've seen so far is to just cull every cane/branch outside the main stem except vines running on the structure. It would be a year without fruit, but it puts me into a great position for the future.
Not sure if I should just eyeball dead vs live canes during the winter or just cull them all
These look like a Concord offshoot breed so that is good advice. I can't start trimming for 2 weeks, so by that time it mah be difficult to determine, what to trim.
I could video call you and you say 'cut' or 'no cut'
