Die-off

Die-off causes branch and plant death through various mechanisms. You see progressive dieback from branch tips. Environmental stress or disease causes this condition. Prune out dead wood and improve tree care to promote recovery.

Cultural management is your first line: remove infected material, clean up debris, and improve the growing environment to make conditions less favorable for the pathogen. Avoid wounding plants during maintenance, as many pathogens enter through fresh cuts. Chemical options are available for severe cases, but they work best as preventive treatments applied before symptoms appear.
