Troubleshooting
Acerola problems — and how to fix them
Acerola (Malpighia emarginata) 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.
Fruit drop
Caused by irregular watering or drought stress during fruiting; keep soil evenly moist and avoid letting the shallow root zone dry out.
Iron chlorosis
Yellowing between leaf veins on alkaline or waterlogged soils; correct pH, improve drainage and apply chelated iron if needed.
Root-knot nematodes
Acerola is susceptible in sandy soils, causing stunting and poor vigour; use clean potting mix and resistant rootstock where available.
Cold damage
Leaf and twig dieback below about 5°C; protect or move containers indoors before frost.
Prevent acerola problems before they start
Most acerola issues are care-mismatch, not bad luck. Dial in the basics:
