Hi, I'm planning a very small vineyard in the UK. In my region I've spoken to several vineyard owners who all bemoan their use of timber posts and so I'm looking into the use of metal trellis systems. Some of the few companies who supply such metal trellis also sell screw in ground anchors (galv steel) or aluminium arrow head style drive in anchors. The aluminium anchors either use a galv steel cable or a stainless wire to run from the anchor to the surface. The manufacturers state their suitability in "suitable soils" or "neutral soils". I guess their concern is to avoid corrosion of either the cable or the anchor itself.
I can't be too choosey with my soil and its wet / sodden clay in winter and damp to cracked / dry in summer. pH is around 6.5. Has anyone experience of such aluminium arrow head style anchors in my sort of ground conditions please? How long have they lasted? Did the cable / wire of alum arrowhead fail first or possibly not at all? etc. etc.
I've not had any problems with these anchors so I'm not suggesting they are of no use. I'm just doing my research first off to make the right choice.
Many thanks and I look forward to any comments.
regards, Mark
