Extending grape vine...
 

I live in central Florida about 2 miles from the Gulf and have a split-rail
fence with a tremendous grape vine growing on it, I would estimate the vine
is 15-20 years old, and I would like to add another 24 feet of fence to it
and I was wondering what I could do to help the vine extend along the new
fence or will it do it naturally? If it does it naturally how long do you
think it would take? Thanks.
