Troubleshooting
Chinese Juniper 'Itoigawa' problems — and how to fix them
Chinese Juniper 'Itoigawa' (Juniperus chinensis 'Itoigawa') 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 leading cause of juniper death in bonsai; soggy or dense soil suffocates roots and the tree slowly browns. Use a gritty mix and water only on a drying cycle.
Hidden decline after browning
A stressed juniper can stay green for weeks while already dying, so damage is often spotted late. Avoid repotting and heavy styling in the same season and watch vigour closely.
Spider mites
Hot, dry conditions bring mites that bronze and weaken the foliage. Check for fine webbing, hose down foliage, and treat with miticide or horticultural oil.
Juniper needle blight / phomopsis
Fungal dieback browning shoot tips, worse in damp stagnant air. Improve airflow, remove affected foliage, and apply a suitable fungicide if it spreads.
