High cordon table grape trellis

I'm hoping to try my hand at growing a grape vine. I found the perfect location minus a possible problem.

I want to use a high cordon trellis at 5 feet tall. But the first two feet will be in complete shade.

If i grow the grape vine in a container until the trunk is at least four feet tall before planting into the ground can a 4 foot grape vine survive if the first 2 feet are in shade? Everything above 2 feet will be full sun.

Also can grapes handle being near roots from hostas?
Thanks

Yes that will work fine.  My red vines start at the base of a large pear tree and are in shade at the base and under the canopy of the tree but extend 100 feet in east west directions on a trellis wire 6 feet high above a fence to keep the deer out of the garden.  The deer help prune the tips of the vines for better production but do not eat the older leaves.

This is super great news. You just made my day. Thanks.

I'm thinking of trying einset seedless but would love to hear what others recommend.
