Eradicating Trumpet Vine: A Multi-Year Battle Plan

Holly in Illinois (Zone 5) wants to remove a trumpet vine embedded in chain-link fence (trunk grown into fence). Cutting it back caused vigorous regrowth. Runners appear up to 30 feet away, clipped at ground level, dug out.

Removal Steps

1. Cut all blooms first to prevent seed spread.
2. Use heavy equipment (backhoe) to remove fence and vine trunk completely.

Runner Management (Three Reproduction Methods)

• Seeds (prevented by bloom removal).
• Rooting where vine touches ground.
• Underground runners (the main problem).

Killing the mother plant does little to stop runners.

Long-Term Strategies

1. Dig/pull like ivy: Persistent, may never fully eradicate.
2. Eco-friendly: Boiling water + salt or white vinegar on infested spots. Clear vegetation, apply to 3-ft radius around root clusters.
3. Herbicide (glyphosate/Round-Up): Paint on leaves/stems (not spray) to minimize drift. Effective but environmental/health concerns.

Expect years of diligent effort. No magic solution.
