Our apple tree were cut down before we moved but grew again , we have been here 6 years , 3 years ago we got 3 apples of two tree's, last year no apples, this year lots but the are rotton in the middle
So here are the trees. One on the left now has pears, the one on the right has apples The big one with no fruit Leaf on the tree which now has pears Pears! Leaf on the tree which has apples on it Apples! Growing out of the stump of the plum tree Fungus on the little apple tree. Looks the same as what was on the plum tree. The plum tree branches were rotted and black in the middle but still had stacks of fruit on. We were advised not to eat the fruit. If the apple tree is the same do we have to cut them all down?
Exactly what @Pony said. It's essentially reverted to whatever rootstock it was grafted onto That looks like honey fungus to me. Google it. Not good
Take the fungus off. Literally cut it out and get as much as you can like a cancer for lack of a better example. Then paint the wound with some sealing stuff that you can get from garden centres to stop fungi getting into open wounds. It might be too late but worth a try Prune it in the autumn gently. Again painting any wounds. Aim to remove any crossing branches and have a general shape up. Go easy on it though as it will be suffering from the attack from the fungus Good luck
That fungus is one I m not familiar with. Could you take another photo at a different angle please. Honey fungus is a capped fungi usualy growing in clumps. If you dig into the rootzone there will be a strong mushroom smell and you'll find "bootlaces" black strands of mycelium. The main problem with infected trees is that the roots need to be removed aswell as the fungi are still present in them. Everything in the pictures is correct, nowt strange going on there.
