Troubleshooting
Atlas Poppy problems — and how to fix them
Atlas Poppy (Papaver atlanticum) 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.
Short lifespan
Individual plants typically live 2–3 years. Allow free self-seeding to maintain a colony.
Crown rot
Wet winters can kill the crown. Improve drainage with grit; grow in raised beds in heavy soils.
Aphid infestation
Clusters of aphids on stems and buds in spring. Encourage ladybirds and other predators; water jets dislodge colonies.
Powdery mildew
May appear on foliage in hot, dry summers after flowering. Usually cosmetic only.
Unwanted self-seeding
Can spread prolifically. Deadhead immediately after flowering if naturalising is not desired.
