Am looking to grow grapes and was considering constructing a trellis out of
1 1/4" galvanized pipe. I was planning on driving the vertical runs about 3
feet below grade(frost line here) and running 1 1/4" horizontal piping runs
about 7 feet high off them. A few concerns came to mind.....the horizontal
runs will be about 10 feet long....is that long enough? The vines will be
trained along the piping. Due to the size of the piping will it tend to get
too hot for the vines as the direct sun shines on them, thus burning the
vines and leaves? I'm in the northeast. Thanks in advance.
