Troubleshooting
Bog Bilberry problems — and how to fix them
Bog Bilberry (Vaccinium uliginosum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Iron chlorosis in alkaline or compacted soils
Interveinal yellowing indicates elevated soil pH or compaction limiting iron uptake. Amend with sulphur chips or chelated iron, use rainwater for irrigation, and work acidic organic material into the planting hole to correct the pH.
Root rot from poor drainage in heavy soils
Despite tolerating moist habitats, the plant cannot stand waterlogged clay or stagnant drainage; roots rot and the plant declines rapidly. Improve drainage with coarse grit, raise the planting bed, or grow in a container of ericaceous compost.
