Pests, Disease & Emergency Rescue

A sick bonsai gives you weeks, not days — but only if you read the symptoms correctly. This is a diagnostic guide, organised by what you can see rather than by pest name.

What's inside

• A symptom-first decision path: yellow leaves, dropped leaves, white fuzz, sticky residue, black spots, brittle branches
• The five pests a beginner will actually meet — spider mites, scale, aphids, fungus gnats, mealybugs — with how to confirm each one
• Root rot: how to check without killing the tree, and what recovery actually involves
• Treatment ladder from least to most drastic, so you do not reach for a systemic insecticide on day one
• Quarantine, and why a new tree should not join the others immediately
• Emergency triage for a tree that has been forgotten, frozen, scorched or knocked over
• How to tell a dying tree from a dormant one before you throw it away
• When a tree is genuinely gone — an honest chapter
