Troubleshooting
Calibrachoa 'Superbells Trailing Blue' problems — and how to fix them
Calibrachoa 'Superbells Trailing Blue' (Calibrachoa × hybrida 'Superbells Trailing 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.
Bare, leggy stem bases
Long trailing types can go bald at the centre if starved or shaded. Feed weekly, keep in full sun and shear back the longest stems mid-season to force fresh branching.
Iron-deficiency chlorosis
Yellow leaves with green veins signal iron lock-out in alkaline compost. Use an ericaceous mix and a chelated-iron or acidic fertiliser.
Drying out and wilting
Long trailing baskets lose water quickly and wilt fast in heat. Check daily, water thoroughly at the base, and consider a water-retaining compost or self-watering basket.
Crown rot in wet spells
Matted, poorly drained trails rot at the crown. Ensure free drainage, water in the morning and improve airflow around the basket.
