I am a total beginner at gardening, and am having a go at trying to grow a grapevine for fun :) I am looking for some advice before I prune it, because I don't want to do something damaging.
The grapevine is a "boskoop glory" variety, and I planted it in early spring this year. It is maybe only a year or two old in total. Over the summer it has grown to around 1m tall in total. It looks like this:
It's maybe not so easy to see in the photo, so I have added a drawing. There are two branches at about 30cm from the bottom, and another two at about 40cm from the bottom. All branches are a similar thickness.
I thought that a good way to grow this would be with some horizontal wires across the fence, so get something like this style:
But then my instinct says I should cut off the bottom two branches of my plant completely, and try to train the top two horizontally. Is this a good idea? It feels like the bottom two are probably a bit too low to train across some horizontal wires.
Also, does it look like I should make other cuts at this stage? Should I remove the bunches of fruit completely at this point, to concentrate on growing the structure? As I say, just learning, so help would be great!
