Q.Sooty Canker disease.
Mock orange shrub developed sooty canker and was removed. Question: Does canker disease (spores)live in soil after plant has been removed? If so, what can I do to prevent disease from spreading to any replacement or surrounding plant. Thanks for the help. Georgian

Yes, it can live in the soil, but not for very long periods. After the tree is removed, make sure to remove as much of the debris from the tree as possible, such as leaves or bark. Treat the area with a fungicide and then wait 1 full year before planting anything new in that area.
