Moving a clematis

Hi all, as above when is the best time to move an established plant and how low should I cut it. Also what would be the best to put in new hole, thanks for your time!

 

I would move it while the plant is dormant before the new seasons growth starts - probably in late winter as long as the ground is not frozen. Prune back the top growth to about 12" /18" and dig at least a 12 inch diameter hole to ensure you get the root ball out in tact.

 

I recommend Q4 clematis fertiliser. I put a handful in with newly planted clematis a few months ago and they have grown strongly and flowered well- much better than similar plants I put in last year without fertiliser. It's about a fiver for a decent sized box.
