Q.New Growth On Maple Tree Is Stunted And Blackened. Why?
This year’s new leaves are mostly stunted and curled and many have blackened edges. We did have a late frost in the spring. Could this be the cause or is there another problem?

Unfortunately, your photos did not come through. This sounds like an infection, rather than frost related issues. This can happen from saturated soils, or soils that do not have a chance to dry out between waterings.
For now, you can try fungicides/bactericides. Some are broad spectrum and some are specialized. Using a specialized fungicide will require knowing exactly what infection is taking hold. Broad spectrum can help with many illnesses.
