Hello - is there anyone with knowledge of tree health - in particular Oak? My suburban garden is dominated by a wonderful Oak tree abt 55 yrs old and 50ft high. It has struggled this year for the 1st time in its life - the first leaves soon curled and looked almost dirty rather than fresh. I assumed it was the cold, but maybe it was the first stage of mildew - a second try of leaves which looked normal have now become covered in white/grey mildew. Dried leaves are now (end July) falling as though it is autumn. (The bark looks fine and no sign of insect infestation).
Will the tree die?
