Double Pink Oleander problems — and how to fix them
Double Pink Oleander (Nerium oleander 'Mrs. Roeding') 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.
Oleander leaf scorch (Xylella fastidiosa)
A bacterial disease spread by sharpshooter leafhoppers causing progressive yellowing and browning of leaf margins from the tips inward. No cure exists — remove and destroy infected plants and avoid replanting oleander in the same spot. Report suspected Xylella to local plant health authorities.
Oleander caterpillar (Syntomeida epilais)
Orange-and-black caterpillars that defoliate plants rapidly, common in Florida and the Gulf Coast. Hand-pick and destroy small colonies; treat larger infestations with Bt (Bacillus thuringiensis) spray. Regular inspection of undersides of leaves reveals egg masses early.
Scale insects
Oleander scale (Aspidiotus nerii) forms white, waxy discs on leaves and stems, weakening growth. Treat with horticultural oil in spring before hatching of crawlers; systemic insecticides are effective for heavy infestations on larger shrubs.
