Troubleshooting
Panicle Hydrangea 'Vanilla Strawberry' problems — and how to fix them
Panicle Hydrangea 'Vanilla Strawberry' (Hydrangea paniculata 'Renhy') 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 stems
Heavy panicles can bend stems, especially after rain or over-feeding; prune by about a third in early spring to build sturdier stems, or stake.
Weak colour in shade
The pink-to-red aging needs sun; in too much shade blooms stay pale and the show is muted. Grow in full to part sun.
Leaf scorch in heat
Edges brown in intense sun and drought; keep well watered and mulched, with light afternoon shade in the hottest regions.
Powdery mildew
Possible in humid, crowded sites; ensure airflow and avoid overhead watering, though panicle types are fairly resistant.
