North Humberside, United Kingdom
The trunk of my old apple trees has turned bright orange and the bark is coming off. There are some very tiny black insects on the trunk which appear to be dead. What is it and what do I do?The tree fruited OK last year and the leaves seemed uneffected, but the orange colour is creeping up the trunk.
The actual colour is deeper than the photograph and you can see what seems to be small dead insects on the detail picture.
