How to prune cooking apple tree
We moved in last summer and have a cooking apple tree (as well as several other fruit trees) that from the looks of it has been pretty much neglected over the last few years.
i have been looking up how to go about pruning these trees but I am unsure of how to prune this cooker. It has a main central 'trunk'/branch which is around 3 metres tall now, with many further branches coming off it further down. Can I cut this central stem to open up the centre and try to keep the tree at a more manageable height for the future.
and if so, do I then have to put a special paint on this cut?
