Eradicating Lawn Ivy: Persistent Broadleaf Weed

Massachusetts homeowner battling ivy in lawn. Herbicides ineffective. Needs viable strategy.

Why Ivy Wins

• Waxy leaves shed herbicide
• Extensive rhizome/stolon network
• Shade tolerance > grass
• No selective herbicide labeled for ivy in turf

Strategy: Precision Glyphosate + Persistence

Phase 1: Targeted Kill

• Two-person cardboard shield method:
• Person A: Holds two cardboard pieces around ivy stem (above grass)
• Person B: Sprays glyphosate on exposed ivy
• Hold shield 10 sec to prevent drip
• Move systematically

Phase 2: Vigilant Follow-Up

• Weekly patrols, same pattern
• Pull EVERY sprout immediately (photosynthesis starvation)
• Spot-spray regrowth with glyphosate gel/brush
• Overseed damaged grass spots

Alternative: Total Renovation

• Glyphosate entire area
• Wait 3 weeks, confirm ivy dead
• Till, amend, reseed
• Only if ivy >50% coverage

Cultural Prevention

• Mow high (3.5-4") - grass shades ivy
• Dense turf via overseeding/fertility
• Improve light penetration (prune)
• Edging barrier (6" deep) to stop lateral spread

Timeline

Monthly precision spraying + weekly pulling = 1-2 seasons for control. Then eternal vigilance. Ivy doesn't surrender—it retreats.

No magic bullet. Cardboard shield + glyphosate + persistence = only reliable method.
