Pear Tree training
I have a five year old Conference pear (dwarfing rootstock) which has never been pruned. It has grown strongly in a upright candelabra shape to about 2.5 m high but never fruited. Is it now to late in its life to prune and train as a 'Palmette' or U shaped Espalier ? If not when can I start this process and how/when do I make the initial pruning cuts ?
