Troubleshooting
Itoh Peony 'Bartzella' problems — and how to fix them
Itoh Peony 'Bartzella' (Paeonia 'Bartzella') 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.
Slow to establish
Itoh peonies invest in roots first; expect modest flowering for the first two seasons before the plant bulks up and blooms heavily.
Failure to bloom
Usually a crown planted too deep or too much shade. Replant with eyes 2.5-5 cm below soil level in full sun.
Botrytis blight
Wet springs can blacken emerging shoots and buds. Cut out infected tissue, improve airflow, and remove all foliage at the end of the season.
Leaf scorch on flowers
Intense afternoon sun in hot climates can bleach the yellow blooms quickly; a little afternoon shade prolongs colour.
