Troubleshooting
Tail-leaf Tolumnia problems — and how to fix them
Tail-leaf Tolumnia (Tolumnia urophylla) 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.
Crown rot
The most common killer — water lodging between leaf bases leads to bacterial or fungal rot. Water at the base of the mount only.
Dehydration on mounts
Mounts dry very fast, especially in centrally heated rooms. Daily misting of roots or relocating to a humidity tray is needed in winter.
Mealy bugs
Waxy white insects hide in leaf axils. Treat with diluted neem oil or systemic insecticide; repeat every 7-10 days.
Bud blast
Flower buds drop before opening due to sudden temperature change, dry air, or ethylene from ripening fruit nearby. Keep conditions stable.
Root loss
Roots turn brown and hollow from overwatering or medium breakdown. Repot into fresh medium if more than half the roots are dead.
