Troubleshooting
Stilt Palm problems — and how to fix them
Stilt Palm (Iriartea deltoidea) 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.
Cold damage
Intolerant of temperatures below 18°C; any chilling causes severe frond damage and potential loss of the growing point.
Low humidity stress
Frond tips brown and die back rapidly in dry air; a high-humidity greenhouse environment is essential outside tropical climates.
Root disturbance sensitivity
The stilt root system is sensitive to major disturbance; avoid repotting unnecessarily and plant out only when the specimen can remain permanently.
Scale insects
Check the stilt root bases and frond midribs; treat with horticultural oil spray.
Spider mites
Present a risk in warm, dry indoor conditions; increase humidity and treat promptly with neem oil.
