The course started with a bit of theory, in the polytunnel they used as a classroom, and then moved out into the orchard to prune the trees ourselves. They took a lot more off the trees than I thought they would, but in doing so showed us the shape we should be aiming for and how to manipulate the branches that are left.
We were given so much information in just one day, I think I’ll book myself on the advanced pruning course in March to make it sink in better (and maybe the summer one as well).
