Pruning the Apple Orchard

In 2012 we planted 200 tress, all cider varieties which were sourced from John Worle of Hereford.  The trees were given a mild pruning but this season it was decided that we need to give them a good pruning to try and encourage wind flow through the apple orchard and the adjoining vineyard.  We managed to prune 150 trees, the balance will be done next season... we simply ran out of time.
