Black spots in sycamore leaves

QuestionsBlack spots in sycamore leaves
Winsome Cunningham Staff asked 8 years ago

I make leaf mould every year. The leaves are mainly sycamore and have black spots. When planting a new Acer earlier this year I applied some of the leaf mold. Will this have an adverse effect on the Acer? Can I continue to make leaf mould with leaves that have the black spots?
