Troubleshooting
California Juniper problems — and how to fix them
California Juniper (Juniperus californica) 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 overwatering
The most common killer. Yellowing or browning foliage and a sour-smelling soil signal waterlogged roots; switch to a gritty mix and let it dry between soaks.
Foliage browning indoors
Kept inside, this sun-loving desert conifer declines steadily. Move it permanently outdoors into full sun.
Spider mites
Hot, dry, still air can trigger mite infestations that bronze the foliage. Improve airflow, spray foliage with water, and treat with horticultural oil if needed.
Weak inner growth
Insufficient light or over-fertilising causes leggy, open foliage. Maximise sun and use restrained, low-nitrogen feeding to keep pads tight.
