David and All: I remember someone burying 5 foot pieces of telephone poles, cross-wise, perhaps 3-5 feet deep at the end of a row. Most of the trellises I built in Biglerville PA survived.
I did have a Geneva Double-Curtin grape trellis fail when, after a big wind storm flipped up one side of the Double-Curtin grape trellis, the terrific imbalance caused the posts to snap off. Come on where are all of the experts like Jon Clements or others who are the experts. I thought that one (or by now several) states had Extension Bulletins on this subject.
