Troubleshooting
Adriatic Bellflower problems — and how to fix them
Adriatic Bellflower (Campanula garganica) 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.
Root rot in heavy soil
Clay or compacted soil retains moisture and causes root rot. Amend planting areas generously with grit or gravel, or grow in raised beds. Avoid planting in low-lying areas where water collects.
Leaf miner
Occasionally affected by leaf-mining flies that leave pale tunnels in the foliage. Remove and destroy affected leaves; serious infestations are rare. Maintain plant vigour with correct conditions.
Over-spreading
Can self-seed freely and spread more than expected in ideal conditions. Deadhead spent flowers before seed sets to manage spread, or thin colonies in spring.
