I pollarded our cherry tree last Winter. It has since put out new shoots and
is looking reasonably healthy but today I noticed resin has exuded from a
few places on the trunk. It is hard to the touch - like amber. There are a
couple of pieces as large as a thumb.

Does the tree have a disease? Is it related to the pollarding?

My first thought would be that maybe some insects got under the bark via the
exposed wounds when you pollarded it and are now doing damage causing the
resin to form as part of the trees defence mechanism?

Certainly happened to an old tree of mine in a former garden. There was
already a split in the bark so this would make sense.

Don't want to worry you, but AIUI cherries are best pruned when in
active growth so that the wounds heal quickly, otherwise there is a
danger of silver leaf disease getting in. But whether the trunk
exuding resin is a symptom of SLD, I've no idea. Silvery leaves and
shoot and branch dieback are the obvious symptoms.

Here in the U.S. we have a borer that gets into all trees that have pits for
seeds (peach, cherry, plums, apricots, and nectarines). To get rid of them,
we spray the trees while still dormant, but just before the leaves come out.
This coats the tree and will kill anything trying to eat into it. Some get a
latex house paint and mix a little bug poisen into the paint and paint the
tree from the second or third limb down to toe roots below the first inch of
the ground. Others will take a strand of wire that is fairly stiff, and
stick it into the hole in the tree, behind the ball of sap and jab it
upwards in an attempt to kill the borer.

Lilacs have a seperate borer, but it will also go to your fruit trees if
they are close enough. I cant tell you which method is the best, because I
still have problems with them. Good luck.

Actually the wounds don't heal. They are quickly sealed by...

an amber like resin
