Unfortunately, there are not a lot of products on the market labeled for creeping myrtle (also known as vinca minor and periwinkle flowers) as they are typically considered a desirable plant species. Manual removal methods and herbicide applications with Glyphosate or Triclopyr are effective in eradicating vinca minor/creeping myrtle/periwinkle however it generally takes several seasons to matter which method is used due to the hardiness and roots that extend several feet. For best results, cut stems 1 to 2 inches from the ground and applied when temperatures are between 60 to 85 degrees. Roundup Pro Max is a non selective herbicide that contains a surfactant for faster burndown and better adhesion to the waxy cuticle on the leaf surfaces. Use precautions if spraying in turfgrass areas or around desirable plants, shrubs, flowers, etc as this will generally kill whatever applied to. Any areas can be reseeded or planted in after 2 weeks. Triclpopyr Ester when mixed with a non ionic surfactant can be used to treat brush, vines, or woody weeds. DO not use a surfactant with Triclopyr Ester when treating cool season turfgrass. Alligare Triclopyr 4 is recommended for non crop areas, ornamental turf, rangeland, grass pastures, etc. This is an oil based insecticide labeled for woody plants and perennial and annual broadleaf weeds. We recommend contacting your Master Gardener Division with the County Extension Office for their recommendations on timing and successful tips they have found in your area.
