Troubleshooting
Hydrangea 'Incrediball' problems — and how to fix them
Hydrangea 'Incrediball' (Hydrangea arborescens 'Abetwo' (Incrediball)) 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.
Wilting in heat
Smooth hydrangeas wilt dramatically when soil dries. Water deeply and mulch; plants usually recover overnight once rehydrated.
Stem flop after rain
Even strong stems can bow under waterlogged giant blooms. Prune to about 30 cm (12 in) in late winter to encourage thicker, more upright new growth.
Few blooms
Too much shade or autumn pruning removes flower potential. Give more sun and prune only in late winter/early spring.
Leaf spot
Fungal spotting in wet, crowded conditions. Avoid overhead watering, space plants for airflow, and clear fallen debris.
