    Does anyone know a way to get rid of leaf spot on Chaenomeles? I have got "Pink Lady". I have read all the RHS stuff but has anyone found something that actually works? poppikin

    Have you tried any of the products mentioned by the RHS in the chemical control section? I presume you are not growing them for human consumption. https://www.rhs.org.uk/advice/profile?PID=745 Blackstart

    Thank you Blackstart. I mentioned in my first post that I had read all of the Rhs stuff. I was asking if anyone had experience of something that actually works. poppikin

    I have been in touch with RHS Advisory and you maybe amused to hear that they say they have not heard of any black spot disease on Chaenomeles. It can get fireblight and canker, but neither of these causes a leaf spot. They would not suggest using a fungicide, because any black spot on the leaves is not likely to be a disease. I have sent in a sample. poppikin

    Afternoon; I can explain the confusion/misunderstanding. You are growing a Japanese Quince (Chaenomeles speciosa) relevant RHS page https://www.rhs.org.uk/Plants/3463/i-Chaenomeles-speciosa-i/Details As the RHS advisor said this does not suffer from Quince leaf spot. Quince leaf blight affects the Common Quince (Cydonia oblonga). Both are commonly called quince and are members of the Rosaceae and both can suffer from fireblight.

    Hopefully the sample you sent will allow them to identify the problem with your Japanese Quince.

    Nigel thinking about your message, thank you again, it's strange that RHS Advisory didn't mention that in their written reply that I related in my post. They now have the sample so we shall wait and see. It may take some time.
