The trellis should have been treated when it went up about 2yrs or so ago but wasn't. It's free standing about a ft in from the fence with a ft wide slate path behind, so accessible from behind.
Ivy and honey suckle aren't well established on the trellis so could easily be untwined. There's a potato plant whose branches can't be untwined but me thought it would be ok if these got a little wood stain on. I'm happy to prune the Lavatera down, it's a rigourous plant and will survive a sever pruning.
Here's the problem... I'm not sure when to prune back clematis...Freckles and jingle bells are well established, both evergreen and cover the middle section of the trellis, they're just coming to the end of flowering and look really lush. There is also a summer flowering clematis grown in between them to flower between May and September which looks almost dead but has started to put out shoots and grows in the branches of freckles and jingle bells.
The Q is , the trellis needs painting and the clematis will need to be cut back/pruned, can this be done now and how far back can they be pruned...
