Troubleshooting
Parsons Juniper problems — and how to fix them
Parsons Juniper (Juniperus chinensis 'Parsonii') 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.
Root rot from wet soil
The most common killer. Plant only in well-drained ground and avoid overwatering or heavy clay.
Phomopsis / Kabatina twig blight
Fungal browning of branch tips, worse in shade and humidity. Prune out affected tips and improve airflow.
Spider mites
Cause stippling and bronzing in hot, dry conditions. Hose down foliage and treat heavy infestations.
Bagworms
Larvae in spindle-shaped bags defoliate junipers; handpick or treat with Bt while caterpillars are small.
