Troubleshooting
Weeping Blue Atlas Cedar problems — and how to fix them
Weeping Blue Atlas Cedar (Cedrus atlantica 'Glauca Pendula') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot (Phytophthora spp.)
Poorly drained soil causes crown yellowing, needle drop, and eventual death. There is no effective treatment once established; prevention through site selection and good drainage is essential.
Cedar aphid (Cedrobium laportei)
Heavy infestations cause needle yellowing and premature drop. Apply insecticide in late summer when colonies are active, or use systemic treatments for established trees.
Snow and ice damage
The long, weeping branches are prone to breakage under heavy snow or ice load. Gently brush off accumulated snow after snowfall. Staking and training can help direct branch orientation to reduce accumulation.
