Troubleshooting
Legacy Blueberry problems — and how to fix them
Legacy Blueberry (Vaccinium corymbosum 'Legacy') 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.
Iron-deficiency chlorosis
Pale leaves with green veins from soil that is too alkaline. Mulch with acidic bark, irrigate with rainwater, and feed an ericaceous fertiliser to correct it.
Bird predation
Birds take ripe berries fast. Net or cage the bush from first colour until the crop is picked.
Mummy berry
A fungal disease causing shrivelled, hardened fruit and shoot blight in wet springs. Remove fallen mummified berries and improve airflow and sanitation.
Under-watering
Shallow roots make the bush quick to wilt and shed fruit in dry spells; maintain steady moisture, especially while berries swell.
