Troubleshooting
Sunshine Blue Blueberry problems — and how to fix them
Sunshine Blue Blueberry (Vaccinium corymbosum 'Sunshine Blue') 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.
Container drying out
Its compact pot-friendly habit means the rootball can dry quickly. Check moisture daily in summer and never let containers fully dry.
Chlorosis from tap water
Repeated hard-water irrigation raises pH and yellows foliage. Switch to rainwater and refresh with ericaceous feed.
Insufficient sun
Too much shade gives soft growth and a light crop. Site in the sunniest spot available for full fruiting.
Bird predation
Sweet berries draw birds. Net the bush once berries start to colour.
