Paeonia lactiflora 'Karl Rosenfield' (Paeonia lactiflora 'Karl Rosenfield') 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.
Non-flowering
Typically due to eyes planted too deeply, too little sun, or over-feeding with nitrogen; correct by replanting shallowly (3-5 cm) in full sun.
Botrytis blight
Damp springs bring grey mould to buds and stems; cut out infected growth, improve spacing for airflow, and clear all autumn foliage to limit reinfection.
Heavy blooms flopping
The large double red flowers weigh stems down, especially after rain; place grow-through hoops or stakes early in the season.
Ants on buds (harmless)
Ants attracted to bud nectar cause no damage and need no treatment; they leave once the flowers open.
