I usually use the midland style because that’s the style I was originally taught by Nigel Adams and because it’s a beautiful style, if somewhat wasteful with the binders used on top. It makes for for a very dense and relatively strong hedge.

That being said there’s a lot of other styles each with their own histories and use cases.

If you want to learn there’s some books on the topic, though not all of them in English. For instance the Dutch stichting heg & landschap has a decent guide and overview of the most common styles and techniques in the Netherlands and Flanders (Heggenvlechten en haagleiden in Nederland en Vlaanderen). A very in depth one is “Europe’s field boundaries” by Georg Müller, but I suggest trying to find it in a library as it’s very expensive.

In order to actually learn the techniques the best way is to find a teacher or course near you. There’s a lot of videos on youtube and pictures in the aforementioned books, but those aren’t really a replacement for someone experienced showing you the ropes.
