Troubleshooting
Ilama problems — and how to fix them
Ilama (Annona diversifolia) 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.
Poor fruit set
Flowers are protogynous and self-pollination is inefficient; hand-pollinating with collected pollen at dusk dramatically improves set.
Root rot
Heavy or waterlogged soil suffocates roots. Plant in free-draining ground and let soil dry between waterings, especially in the dormant season.
Mealybugs and scale
Sap-sucking insects cluster on stems, fruit and leaf undersides, leaving sticky honeydew and sooty mould; treat with horticultural oil or insecticidal soap.
Cold and frost damage
Even a light frost defoliates or kills the tree; protect or move containers indoors when temperatures approach 2-4°C.
Prevent ilama problems before they start
Most ilama issues are care-mismatch, not bad luck. Dial in the basics:
