Chestnut Tree what is wrong with the trunk?
Glasgow,
United Kingdom 
There is a lovely chestnut tree in the communal gardens but about 3 years ago I noticed a sticky patchy oozing out of it. Now I have noticed the trunk is shedding its bark almost like a snake shedding its skin. Otherwise the tree is in full bloom leaves look healthy.

From an article in The Independant -
The trees have already been stressed by three winters of drought. But now in their weakened state they are suffering from simultaneous attack by a pest, the leaf miner moth, whose larvae eats the leaves, and a disease known as bleeding canker.
This causes a dark liquid to ooze from spots on the trunk of a tree, which can quickly develop into large damaged patches, spreading all the way around the branch or trunk until limbs fall off, or the tree falls over.

There is no chemical treatment currently available.

Try pouring a Jeys fluid diluted solution on the wound it workd for me with our 200 yr old Horse Chestnut tree.
