Troubleshooting
Hydrangea 'Limelight' problems — and how to fix them
Hydrangea 'Limelight' (Hydrangea paniculata 'Limelight') 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.
Weak, flopping stems
Over-feeding with nitrogen or too much shade produces lax stems. Give full sun, prune to a sturdy framework, and feed lightly.
Poor flowering in shade
Needs ample sun for its best panicles. Move or plant where it gets at least six hours of direct light.
Pruning confusion
Blooms on new wood, so prune hard in late winter or early spring; pruning in summer or autumn sacrifices the next year's flowers.
Leaf scorch in extreme heat
Crisp leaf margins during heatwaves with dry soil. Mulch and water deeply; light afternoon shade helps in the hottest climates.
