Troubleshooting
Golden Deodar Cedar problems — and how to fix them
Golden Deodar Cedar (Cedrus deodara 'Aurea') 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.
Loss of golden colour in shade
The 'Aurea' cultivar requires full sun to maintain its golden-yellow foliage. Insufficient light causes new growth to emerge pale green. Ensure no overhead canopy shading develops as surrounding trees mature; re-site if necessary.
Deodar aphid and bark beetle
Phloeosinus bark beetles and various aphid species can infest stressed trees. Keep trees vigorous with appropriate watering and avoid mechanical damage to bark. Severe infestations on young trees can be treated with systemic insecticides, but prevention through good cultural care is preferable.
Frost damage to new growth
The golden new growth emerging in spring is susceptible to late frost damage, turning brown. Site in a frost-pocket-free location. In zones 7, protect young trees with horticultural fleece during forecasted late frosts.
