Easter Heliconia problems — and how to fix them
Easter Heliconia (Heliconia wagneriana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Caterpillar leaf damage
In outdoor tropical plantings, moth larvae (notably Caligo and Opsiphanes species) can cause significant defoliation. Hand-pick caterpillars where feasible, or apply a Bacillus thuringiensis (Bt) spray early in an outbreak.
Fungal leaf spots (Helminthosporium spp.)
Dark brown to black lesions with yellow margins develop during prolonged wet conditions or in overcrowded plantings with poor airflow. Thin clumps, avoid overhead irrigation, and apply copper-based fungicide if lesions spread rapidly.
