Hazel nut queries
Two years ago we bought two named hazel nut trees, and planted them up. They are now strong healthy looking young trees, which bore a few nuts last year, and there are signs of a few to come this year.
My question is this, how do I prune them to encourage more fruiting next year, and in the following years? They cannot be allowed to get too tall due to the place in which they are - but I know I have seen highly productive hazel hedges so that should not be a problem, if only I knew how to set about it. Any help would be greatly welcomed.
