Last year we composted the leaves from the mixed deciduous trees in and around our garden and planned to do the same this year. However, there are ash trees within our collection area, they do not seem to have any of the signs of Chalara ash dieback I have found in my internet research; is it considered safe to harvest ash leaves for leaf mould?
I don't see it as a problem-in the wild they will decompose naturally-despite the disease-in a garden situation you are doing the same
And fungal spores are in the air all the time. I don't think anything we do will alter that.
We have two much loved mature ash trees and are quite anxious about them so I've been listening to and reading everything I can about this. I heard an expert say that the spores would not survive long on fallen leaves and it was quite safe to compost them. I hope they're right - they don't seem to know all that much about it. Anyway, as we'll be using the leafmould in this garden with the trees that grew the leaves, I shall gather the fallen leaves again this year and make leafmould.
Thank you all for your input; still no signs of the disease in our area so leaf mould it is.
