Cedar Flagging

Evergreen plants

17 host plants

Cedar flagging causes tip dieback on conifer branches, creating a browning or reddened appearance. You notice discolored branch tips that die back, leaving thin, bare branches. The condition may be environmental or disease-related. Prune out affected branches and provide proper tree care.

Additional irrigation may be needed during summer drought. Avoid disturbing soil, and thus roots, near plantings.
