Troubleshooting
Rabbiteye Blueberry problems — and how to fix them
Rabbiteye Blueberry (Vaccinium ashei) 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.
Mummyberry (Monilinia vaccinii-corymbosi)
Fungal disease that causes shrivelled, mummified berries. Remove and destroy infected fruit; avoid overhead irrigation; apply fungicide at green tip in high-pressure areas.
Poor fruit set / small crop
Rabbiteye blueberries are largely self-infertile. Always plant two or more compatible cultivars (e.g. 'Climax' + 'Premier') within 3 m for adequate cross-pollination by bees.
Iron/manganese chlorosis
Yellow leaves with green veins indicate micronutrient lockout from pH above 6.0. Lower soil pH with elemental sulphur; use a chelated iron drench as a short-term fix.
