Apricot Problem

[DannyK]

Anyone got any ideas why a branch is dying off.
It's bleeding resin.
Thank you

It has canker, but the looks of it. Apricots are pretty prone to it, and to other random die back of branches, especially in this country, where the winters are really too wet and mild for it (they prefer hot summers but cold, dry winters).

Leave it for now (making major cuts to any Prunus now invites all sorts of infections), then from May, cut out the infected branch, at least an inch or so into clean wood beyond the bleeding section.
If you can't do that (if the trunk is bleeding too, for example), then just cut out the bit that is definitely dead, and keep your fingers crossed that the remaining canker won't girdle the trunk and kill the tree any time soon (sometimes they can live with it for years, other times it can kill them very quickly).
Maybe also give the tree a good feed up, so that it puts on lots of fresh growth to replace that it lost.
