What goes wrong with Brachychiton
| Problem | What you'll see | What to do |
|---|---|---|
| borers | Tunnels in the trunk or branches, sawdust-like frass at the base or entry holes, and branch dieback. | Maintain plant vigour and surgically remove larvae or apply registered systemic insecticides. |
| queensland_fruit_fly | Stings on developing seed pods with larvae feeding inside. | Monitor with traps and clear fallen pods promptly. |
| Borers | Small entry holes in the soft wood of the trunk or stems, often accompanied by sawdust-like frass. | Maintain plant vigour through correct watering, monitor the trunk regularly, and physically remove larvae or prune affected minor branches if necessary. |
| Scale insects | Small, raised brown or white bumps clustered on tender new growth and leaf undersides, often accompanied by sooty mould. | Improve airflow around the canopy and treat infestations with horticultural soap or neem oil spray. |
| Root rot | Softening of the caudex base, yellowing or premature dropping of leaves, and branch dieback. | Ensure sharp drainage, avoid overwatering, and never allow the plant to sit in standing water. |
| sooty_mould | Black, powdery coating on leaves resulting from honeydew-secreting insects. | Control underlying sap-sucking pests like scale or aphids with horticultural oils. |
| Phytophthora root rot | Wilting foliage, soft or discoloured bark at the soil line, and root decay. | Ensure sharp drainage, avoid overwatering, and apply a systemic fungicide if early symptoms appear. |
