Troubleshooting
Blue Atlas Cedar problems — and how to fix them
Blue Atlas Cedar (Cedrus atlantica 'Glauca') 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.
Faded blue colour
Insufficient sun mutes the silvery-blue tone; site in the open and full sun for strongest colour.
Underestimating mature size
Often planted too close to buildings; allow many metres of clearance for its eventual broad spread.
Root rot on wet sites
Yellowing and dieback follow waterlogging; plant only in free-draining ground and never overwater established trees.
Tip blight / needle browning
Browning shoot tips can follow fungal infection or cold winds; prune out affected growth and avoid overhead watering.
