Troubleshooting
Green Gem Boxwood problems — and how to fix them
Green Gem Boxwood (Buxus 'Green Gem') 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.
Boxwood blight
Fungal disease causing dark leaf spots, stem lesions and rapid defoliation. Buy clean stock, water at the base, ensure airflow, and remove and destroy infected debris.
Winter bronzing
Foliage turns orange-bronze in cold, exposed, sunny winters. Site with afternoon winter shelter and water before freeze-up; color usually recovers in spring.
Boxwood leafminer
Larvae mine inside leaves, causing blistering and yellowing. Monitor in spring and treat affected plants with an appropriate systemic if infestation is heavy.
Root rot from wet soil
Shallow roots rot in poorly drained or overwatered ground. Plant in well-drained soil and avoid soggy conditions.
