Astilbe 'Bridal Veil' problems — and how to fix them
Astilbe 'Bridal Veil' (Astilbe × arendsii 'Bridal Veil') 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.
Drought scorch
The most common failure — dry soil causes brown, crispy leaf margins and collapsed plumes. Maintain constant moisture and mulch the root zone.
Powdery mildew
Stressed, dry, or crowded plants can develop white leaf coating in late summer; improve airflow and keep roots moist to prevent it.
Poor flowering in deep shade
Too little light yields lush foliage but sparse plumes; site in dappled or part shade and divide congested clumps every 3-4 years.
Crown heave / division decline
Vigorous clumps push the crown upward over years, reducing vigour; lift and divide in spring or autumn to rejuvenate.
