Default grape vines & walnut trees

Thanks so much for the info.
I have considered cutting the walnut tree down and hadn't made up my mind.
Now I know the tree has to go.
Thanks again for the info.

I would like to start 5 or 6 grape vines on a couple of lots that has a
large walnut tree on the edge. Has anyone heard of trouble growing
grapes around walnuts? I know tomatoes will not grow in close
proximity
to walnut trees.


In the USA wild grapes are resistant to Juglone (the poison in Walnut
trees) and cultivated grapes are susceptible. The toxic zone from a
mature tree occurs on average in a 50 to 60 foot radius from the trunk,
but can be up to 80 feet.
