Pruning Espailer Apple Tree
My house came with this hybrid apple tree that was espalier'd. For the last three years I have been pruning the "shoots" or long branches that come off the main horizontal branched. However I have never seen any buds or fruit develop. This year I avoided pruning at all to see if it would bud. I've not seen anything and I'm wondering what the best practice is now? Should I prune off all the shoots now? Later? Long term when should I be pruning these shoots and is something wrong that I never see buds let alone fruit? Thanks!
