The first picture shows a traditional raspberry support. This is a well established row of berries and the supports do well until the wind blows the wrong direction. If the wind is blowing hard in the direction of the support wires all the canes fall over. In the process of standing them upright again I always manage to break a few canes.
The other picture shows a new method of supporting the raspberry canes. You will notice horizontal wire mesh. The canes will grow up through the mesh and be supported in all directions.
