The clematis growing up my garden fence and into the trees are getting a bit rampant and where I have different varieties growing near each other they are intertwining with each other and with the honeysuckle.
When you prune your clematis do you cut it back to a few main supporting stems which you tie back to trelllis? What shaped trellis is best if you use trellis? I use wire and vine eyes and tie the clematis in, which is fine but no real shape to the trained plant results.
If you use obelisks what obelisks have stood the test of time? Wood or metal?
