Wires for clematis

[SpanielPlusToddler]

I’ve bought a clematis Montana to hopefully cover a 6ft fence in my front garden. I’ve also bought vine eyes and green coated wire, to run horizontally along the fence for it to cling to and help it to spread.

The question I need help with is how many wires? 2 or 3? And what heights? I first thought 2 wires, 3ft and 5ft up from the ground. Does that sound ok or too widely spaced? It’s a decent sized plant, already about 3ft tall ish.

Thanks

C Montana is very vigorous and will aim for the sky. I’d put horizontal wire near the top of the fence and half way up (3 ft). It will do its growing after it flowers in the spring

I planted a Montana against an ugly 6ft shed a couple of years ago and put 3 horizontal wires across the whole thing running the whole width. Within 18 months the whole shed was covered in flowers and leaves - amazing! I wish I'd put more wires in initially because it became quite difficult to do so after it's taken over.

I was watching a C montana in a neighbour's garden - in a very few years it had reached the roof ridge, at which point they were presumably having problems with their roof tiles and removed it.
