Netting is too much of a hassle. Putting it up and taking it down. I did that with blueberries and the netting was always getting tangled up with the plant I think the same with be true with grapevines.
What I’m speaking of is a bird proof caged wire enclosure design for the vines and such. Something permanent. I’ll provide a picture for an example if I can find the thread where a lady designed one. .
