Thanks @Joey66 , I will find it hard to get anything here as they ban all chemicals stuffs EU or Finland I don't know who.We have a stong household cleaner that is often used on Roses so I will give that a go .It looks like mildew or a type of blight - spray with a copper base fungicide or a fungus spray look on e bay as shops are hard to get supply - Home Bargain used to do a rose fungicide spray that will do the job - a systemic fungicide is the best option - Its probably caused by the hot humid weather & will affect the growth of your tree - water it well at the roots - before spraying out of the sun - cloudy or early am![]()
It is not one of our trees but a neighbours I just want to help as it could come our way .The problem with living near so much forest I suppose .
