Troubleshooting
Peony 'Sarah Bernhardt' problems — and how to fix them
Peony 'Sarah Bernhardt' (Paeonia lactiflora 'Sarah Bernhardt') 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.
Failure to bloom
Almost always caused by planting the crown too deeply, too much shade, or excess nitrogen. Lift and replant with eyes no more than 5 cm deep in full sun.
Botrytis blight
Grey mould blackens buds and stems in cool, wet, crowded conditions. Remove affected growth, improve airflow, and clear all debris in autumn.
Flopping stems
Heavy double blooms collapse after rain. Support with grow-through ring supports or hoops set early in the season before stems lengthen.
Ants on buds
Harmless and not a problem; ants feed on the sweet nectar from developing buds and do not damage the plant or trigger opening.
