How to prune field poppy

No structural pruning; remove spent plants in late summer once seeded. Deadheading can extend flowering very briefly — snap off spent petals before pod swells — but is generally not worth the effort. For naturalistic drifts, leave pods to ripen and shatter. Pull and compost the whole plant once it yellows and seeds have dispersed.

Rarely; remove spent plants at end of season only. Field poppy (Papaver rhoeas) is an annual that completes its lifecycle in one season. It does not benefit from cutting back, and deadheading only marginally delays seed set. The ornamental seed pods are part of its charm. Let plants self-seed for successive years, then pull and compost spent stems after pods have ripened.
