Dodder: Parasitic Vine Requires Drastic Removal

Dodder (Devil’s Hair) attaches parasitic roots to host plants, weakening or killing them. No selective herbicide exists. Pull and destroy all infected plants. Next spring, apply pre-emergent (Preen) to prevent seed germination, but still scout regularly. Best: remove top 3″ of soil and replace with clean topsoil to eliminate seed bank.
