Troubleshooting
Hydrangea 'Little Lime' problems — and how to fix them
Hydrangea 'Little Lime' (Hydrangea paniculata 'Jane' (Little Lime)) 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.
No autumn pink colour
Cool nights and adequate sun drive the green-to-pink shift. In deep shade or very warm autumns blooms may stay green.
Sparse flowering
Caused by pruning at the wrong time. It blooms on new wood, so prune in late winter/early spring, not autumn or spring after buds emerge.
Leaf scorch
Crisp brown leaf edges in hot, dry, exposed sites. Water more, mulch, and provide afternoon shade in hot climates.
Powdery mildew
White film on foliage in humid, still air. Improve spacing and airflow and water at the base rather than overhead.
