Thanks @steevec, and cheers🍻 We got two grapevines, a white and this red (blue) one. They're quite easy when they made it over the first year. As soon as the roots are established, cutting back becomes a task (it's no exaggeration if i tell you i have to cut about a mile of branches each year. A single branch can grow more than 15 metres/year, and there are plenty of them).The red one is now 8 years. The main idea behind those is to provide shade during summer, but they for sure have more benefits ;)
