Someone in another group I read wants to move some 100 year old grape
vines . Any chance of success ? My understanding is that they root very
deeply , wondered if that would make it difficult to avoid transplant shock


I have not done it (yet) but I poked around a bit and found several
success stories of moving huge old vines (prune the vine back hard,
first, seems to be a common theme.) Cuttings are easier to handle, but
the old vine will be back to fruiting faster. Remember that grapes fruit
off of new wood and require fairly hard pruning to produce well.

Timing will also matter - you are likely near (or past) the end of the
"spring window" for moving them, and long past the best time for pruning
(dead of winter.) Fall is probably a better time to move, so the roots
can re-establish over the winter. Moving them with leaves on seems
doubtful in the extreme.

You'll be losing a good deal of root material (I don't know how deep
they go, but they certainly go wide, based on the ones I find) but that
will re-grow as well.
