Q.Holly Tree Disease
Thank you for your reply and the web links, but having read through them I cannot see anything resembling my specific problem. The original plant had several stalks/branches and looked in great shape and colour. After 6 months, I noticed one of the stalks had turned brown, along with all the leaves on that stalk. I cut this back to the base, but now another stalk has developed the same all-over brown colour and looks decidedly as though it is dying. The leaves are not curled up nor are there any obvious ‘mites’ or ‘bugs’ anywhere on the plant. No patches or blots on the plant. The rest of the bush looks fine! I hope it is possible to see my explanation from the attached photo? Thanks – IanL

To me, it doesn't look diseased. It just looks like it suffered some transplant shock. I see new growth, with a red tint, and I see just a little desiccated growth. I don't see any indication of an issue that needs resolve. I, only, included the articles on disease to show you the most common that are associated with the species. I do not think that there is anything, particularly, wrong with the shrub.
What I would recommend is to test the soil for pH imbalances or nutrient deficiencies. At the most, there is a slight deficiency that can be corrected with a liquid feed.
Unfortunately, the photo looks to be the same as the last, so I cannot gather any new information from it. But a soil sample will tell you about any deficiencies that might be present in the soil.
