Hydrangea 'Annabelle' problems — and how to fix them

Hydrangea 'Annabelle' (Hydrangea arborescens 'Annabelle') 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 stems

The huge heads weigh down soft stems, especially after rain. Prune less hard to leave a sturdier framework, or use a low grow-through support ring.

Wilting in dry heat

Foliage and blooms wilt fast when soil dries. Site in part shade, mulch, and water deeply during hot, dry spells.

Few flowers after wrong pruning

It blooms on new wood, so cut back in late winter or early spring; pruning in summer removes developing buds.

Leaf spot and powdery mildew

Fungal spotting and white mildew in damp, crowded conditions. Improve spacing and airflow and avoid wetting foliage.
