Invasive Mint Control: No Allelopathic Plant Exists

Gardener seeks a plant allelopathic to mint to outcompete garden takeover.

Reality Check

Mint is an "ultimate invader"—crowds out everything. No plant will displace established mint.

Real Solutions

1. Herbicide: Spot-spray glyphosate (Roundup) — not in edible areas.
2. Manual removal: Dig out by hand (tedious but effective).
3. Repurpose: Plant dug mint under large shade trees—forms fragrant carpet where grass fails.

Bottom Line

No magic plant replacement. Physical/chemical removal required.
