Troubleshooting
Juniper Bonsai problems — and how to fix them
Juniper Bonsai (Juniperus procumbens 'Nana') 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.
Kept indoors
The single most common killer. Junipers need outdoor light and winter dormancy; indoor specimens decline slowly, often greying months after the damage is done.
Delayed death from underwatering
Foliage can stay green for weeks after the roots have dried out and died. Maintain consistent watering and check soil moisture daily in heat.
Spider mites
Common on stressed or indoor trees; foliage looks dull and dusty. Shake a branch over white paper to check, then treat with a miticide and improve conditions.
Root rot
Heavy, water-retentive soil suffocates roots. Repot into a gritty, free-draining mix and let it dry appropriately between waterings.
