Oriental Poppy 'Patty's Plum' problems — and how to fix them
Oriental Poppy 'Patty's Plum' (Papaver orientale) 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.
Dormancy gap
Foliage yellows and disappears entirely by midsummer. Plan planting companions (Aster, Salvia, Geranium) to disguise the gap.
Crown rot
Caused by waterlogging during summer dormancy. Raised beds or very free-draining soil prevents this.
Powdery mildew
Common in dry summers. Usually superficial; remove affected leaves and improve airflow.
Stem collapse
Tall stems may topple in wind or rain. Use grow-through supports or plant adjacent shrubs for windbreak protection.
Slugs
Target tender new spring rosettes. Protective measures in spring protect the regrowth.
