my summer fruiting 'Glen Ample' raspberries have small orange spots/lumps on the leaves......The picture enclosed should describe it better....What is it...? and what to do..? ............Having received a reply from Tg, i used the link to ask The James Hutton Institute in Dundee for an opinion. One of their Plant Pathologists has worked on this...it is apparently Raspberry Yellow Rust...If severe can cause leaf loss with perhaps winter kill of the plants, but extremely unlikely and will probably go away.Destroy the affected leaves, but let them know if it becomes a real problem...Thank you , one and all.
