Chinese Incense Cedar problems — and how to fix them
Chinese Incense Cedar (Calocedrus macrolepis) 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.
Frost damage to young plants
Young specimens are tender; protect with fleece in the first 2 winters in cold gardens.
Root rot
Waterlogged soil is fatal; plant in well-drained sites and avoid irrigation during dormancy.
Aphids on new growth
Clusters of aphids on spring shoots; treat with insecticidal soap or encourage natural predators.
Wind scorch
