Zone 5b (Ontario) my cherry tree's cherries this year all rotted and die from what I believe is/was "blue mold rot".
Now all the leaves are browning and curling up. The brown areas are hard and crispy they fall off the tree easily. Is there anything I can/should do?
To confirm my research into blue mold rot I can spray a sulfur mix after the last frost and before the first buds correct?
