Dieback is a fungal disease that affects the roots and causes leaves to wilt and branches to die back.

It’s caused by the fungus Phytophthora cinnamomi and is exacerbated by wet conditions.

There aren’t any chemical solutions for dieback, so it’s best to prune away affected parts of the plant. If the entire plant becomes infected, you’ll have to replace it.
