Strong Wire Trellis
I've just bought a fairly mature Wisteria, going to grow it up a south facing stone wall (side of the house). I know I need to support it and understand it needs to be strong support. So I believe I need a couple of horizontal steel wires, maybe 4m long, with hoop supports every 1m and a tensioner at one end.
I'd appreciate your advice on whether I've missed anything and any suggestions for the best value to purchase it from (seen some 'kits' online, none seem to be exactly what I want and quite expensive).
