Peonies Sprayed with Weed-B-Gon: Recovery Steps and Future Care

Broadleaf herbicide (2,4-D, dicamba) drift on peonies causes twisted, curling foliage and bud drop. Established peonies have deep roots and often survive a single exposure.

Immediate Response

• Do not cut foliage yet—leaves photosynthesize to fuel root recovery.
• Water deeply to leach chemical from root zone.
• Apply 2-inch composted manure mulch to stimulate soil biology.

Watch & Wait

• If foliage completely withers, cut to ground.
• Roots may resprout next spring.
• Do not fertilize heavily—stress recovery, don't force growth.

Transplanting

Wait until fall (September) to move any survivors. Peonies hate spring transplanting.

Most established peonies bounce back. Be patient.
