We are doing ours now. We had 6 x 1.8m trellis panels dividing th eveggie plot form the mai garden and the posts have gradually succumbed to strong winds and heavy rains and leaned more than Pisa whilsts the panels have rotted or have their middles blown out of their supporting frames.
We used metposts the first time. This time all but two of the posts are out and will be replaced by new ones buried in concrete boots. We will then attach 5m x 2 metre panels of builders' wire mesh for reinforcing concrete. It doesn't rot, doesn't break and will support my assorted clems and roses. We already have some along the back perimeter and I use it to support pumpkins and trained blackberries and tayberries.
We also have a honeysuckle over on the far side and its trellis needs replacing so I shall simply cut back what I can't "untrain", put in new metal trellis as above and let the honeysuckle. It doesn't need tying in but does need twining through to guide and support it.
Posts and metal mesh come from a local builders' merchants who are happy to deliver. Cheaper than garden centres too.
