Troubleshooting
Heart-leaved Globe Daisy problems — and how to fix them
Heart-leaved Globe Daisy (Globularia cordifolia) 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.
Winter wet rot
Prolonged moisture on or around the crown in cold wet winters causes rot and can kill the entire mat. Ensure excellent drainage; in containers, tilt the pot slightly to aid run-off and shelter from persistent winter rain.
Red spider mite
In hot, dry summers under glass or in sheltered sunny spots, spider mites may colonise the dense mat. Look for stippled, bronzed foliage and fine webbing; treat with predatory mites or insecticidal soap.
Failure to flower
Often caused by insufficient direct sun or over-fertilising with nitrogen. Ensure at least 6 hours of direct sun and keep soil lean.
