Today a branch, approximately 30-40%, of my ancient apple tree broke off. It was loaded with apples, one of the heaviest crops ever. The point where the branch broke has exposed a large section of the trunk, which is wet and crumbly in the middle with a more solid outer core. I may have had some fungal attack a couple of years ago - possibly hinge or honey fungus, but I could not really identify it. Or rain may have seeped in from the top of the tear. Do I get rid of all the damp wood, effectively making the tree hollow? Can I repair it, as the branches, leaves and apples seem fine? I don't know the variety. They are like a cross between a Cox and Granny Smith. I would be most grateful for advice. Thank you.

The branch cannot be reattached, unfortunately.
The rot may stem out of several things and does need to be treated. But, for as bad as it sounds, I would recommend bringing a professional arborist in to treat it. In the mean time, you can start to treat the wound with a fungicide to help stave off further damage.
Thanks Heather, after I posted my question and had finished clearing the garden, another branch broke off higher up and with no evidence of the rot lower down. So I am now left with around 30-40% of my tree, but the remaining branch looks sound if unbalanced. what fungicide should I use? thanks :)
