Hello everybody,

I have a 3 year old clematis (2 Jackmanii) that I am trying to train sideways over the two black fences(??) - please see photograph.They have about 3 - 4 stems each and reached about halfway between the two black fences last year. My question is - should I prune them all the way to the ground or should I prune them where they touch the black fence at the top to increase the spread of leaves (and hopefuilly flowers?)

All advice is appreciated.
