I've got some east facing hardifence down the side (1.5m wide) of my house that I would like to cover up. A green living plant will look much nicer than the grey fibre cement, especially when I'm having breakfast and looking out the window.
I have settled on Hardenbergia comptoniana, and will put up some wide spaced wire mesh for it to climb on. The problem is that I am not sure how far apart to space them to cover the fence.
I could take a wild guess and go for 2m spacings, but I'd rather get some first hand opinions about it from anyone who has planted them.
Fu said http://forum.homeone.com.au/viewtopic.php?p=422529#p422529 that you could "cover a verge with one of these" so it makes me think that 2m spacings along the fence may be too conservative.
What is the consensus? 2m, 2.5m, 3m or 3.5m spacings? Or other!
