Troubleshooting
Lowbush Blueberry problems — and how to fix them
Lowbush Blueberry (Vaccinium angustifolium) 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 crop from single plants
Lowbush blueberry is largely self-infertile. Plant several individuals together so insects can cross-pollinate for good fruit set.
Soil too rich or alkaline
Fertile, limed soil causes weak, chlorotic growth. Grow lean and acidic; re-acidify if leaves yellow between green veins.
Weed competition in the low canopy
Vigorous weeds smother the creeping canes. Mulch and hand-weed, as the plant resents being out-competed.
Bird and wildlife predation
The wild berries are a favourite of birds and small mammals. Net plants if you want the harvest yourself.
