Why 2,4-D Will Kill Your Vinca Along with the Vetch

Broadleaf Herbicides Don't Discriminate Among Broadleaves

2,4-D targets broadleaf weeds but cannot distinguish between desirable ornamentals (vinca) and weeds (vetch). Any broadleaf herbicide will damage or kill both.

Safer Alternatives

• Hand-pull vetch on a warm day when soil is moist.
• Apply a pre-emergent broadleaf weed preventer in September to stop winter annuals like vetch and chickweed.
• Spot-treat with a shielded sprayer if absolutely necessary, but risk remains high.

Mechanical removal and prevention are the only safe options in mixed plantings.
