I have a extremely large, (in my opinion), grape vine that has taken over a
split rail fence and it has been there for at least 20 years. I would like
to extend the fence another 25 feet but instead of using split rail I want
to set some 4x4's into the ground and attach "feedlot" panels for the arbor
to run through. My questions are whether or not an arbor that old will train
itself down the new fence and if not, what is the best way to get it to
start running down the new fence? Also, what is the best way to fertilize a
large grape arbor? No more fruit grows on it and that's how I want it, it is
just a big wall of vines and leaves which is what I want but I am not sure
how to fertilize. Thanks very much.

Just train a cane in the direction you want to go and reduce any canes
that may be redundant. It may take 4 - 6 years for it to go 25'. Vines
vegetate if given water and nitrogen. I'd give it a nice shot of fish
emulsion now and also in May, June, and July. I don't know what your
soil is like but if the roots can penetrate it, they can go down to
forty feet.
