We recently took over a house in Liguria, Italy, and inherited this sprawling grapevine growing along our garden fence. It hasn’t been maintained or pruned for several years, and we really want to bring it back to health and manage it properly. However we don't know anything about looking after it.

It probably needs trimming, but I don't know how and whether or not it's already too late in the year for that.

We'll get some wood to build it something to climb on, since it appears to have outgrown the fence.
Anything it needs in terms of nutrients? The leaves appear to be quite small, but not sure if this is a sign of deficiency or overcrowding.

Any help is much appreciated!
