Hi Ginda. Canadice was the only grape I ever grew that I disliked so 
much that I removed it and planted something else.
I'll try to answer your 4 questions but keep in mind that I'm a good 2 
zones colder than you and my experience may not be the same as yours. (I 
have to prune my grapes in the fall and lay the vines flat against the 
1) You can try another grape there but I have no way to know for sure 
how much the shade will affect your new vine. From your description, I 
would think you could get some good grapes.
2) I wouldn't graft it. Canadice is vulnerable to some sort of canker 
that never affected my other grapes. You could tie it to a hitch of a 
truck and try to yank it out but I just cut mine off close to the 
ground. I can't recall if I had to remove any sprouts later or not. I 
didn't plant the new grape at the exact same spot. I moved over about 2 
3) I saw the picture you attached and I've never seen that before.
4) Reliance is a very nice tasting red grape and mine is growing in more 
shade than any of my other grapes. Probably more sun than your location 
though. Vanessa has a nice sweet, fresh flavor too but the grapes are 
slightly smaller than Reliance. Both taste far better than Canadice, at 
least as they grow for me here.
