Contrary to a prior post, I will say DO NOT plant Black Walnut within 50 feet of a grape vine (or any other plant for that matter). The Black Walnuts exeude a chemical from their roots called juglone. It is a growth inhibitor which tries to keep anything else from growing near the tree. Not all plants are susceptable to juglone, but most are.
Walnuts are selfish with their soil!

How do you harvest them with a very looooong ladder?
We wouldn't get a single grape without netting it anyway, for me there's no point letting a grape or a kiwi or anything up into a tree.

Grape Vine companion planting:
Companion plants: Geraniums, Mulberries, Hyssop, Basil, Tansy
Basil - Herbaceous layer – pest repellent
Tansy - Herbaceous layer – pest repellent
Geraniums - Herbaceous layer – pest repellent
Hyssop - Herbaceous layer – helps plant growth
Chives - Root zone – inhibits fungal diseases
Mulberries - Canopy layer – beneficial companion plant
Bad Companions : Radish, Cabbage
