3 year old leaf mould containing cameraria ohridella
We have gathered leaves onto one site for rotting down for at least 3 years. For the last 2 the trees nearby have shown clear signs of the leaf mining moth. We went on heaping them on to our heap. Now we learn that the problem is managed on the continent by burning the leaves. Is there anything we can do to kill any insects in the leaf mould without burning the whole lot?
