Troubleshooting
Hydrangea 'Vanilla Strawberry' problems — and how to fix them
Hydrangea 'Vanilla Strawberry' (Hydrangea paniculata 'Renhy' (Vanilla Strawberry)) 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.
Flopping flower heads
Oversized blooms or too much nitrogen can bend stems. Feed lightly and prune harder in early spring to build sturdier wood.
Poor or no flowering
Almost always from pruning at the wrong time. It blooms on new wood, so cut back in late winter/early spring, never in autumn after buds form.
Leaf scorch and wilt
Hot, dry sites cause crisp leaf margins and midday wilting. Increase watering, mulch, and give afternoon shade in hot regions.
Powdery mildew
White coating on leaves in humid, crowded conditions. Improve airflow, avoid overhead watering, and remove affected foliage.
