How to Control Mile-a-Minute Vine in CT, MA & RI
By ArborActive Team · Updated
This annual vine starts from seed. Early removal and repeat visits matter because a new crop can emerge after the first pass.
Identify the plant
Persicaria perfoliata. Look for triangular leaves, small backward-facing prickles, and a round leaflike collar that the stem passes through. The fruit clusters turn blue. Compare the collar and leaf shape before identifying a tangled vine.
University of Connecticut Extension identification and management guideChoose a control method
Start with the size of the patch, what you want to preserve and whether the site is near water.
Small patches
Pull young vines before they fruit. Protect your hands from prickles and check back for plants missed beneath shrubs or along fences. Collect fruiting vines carefully so seeds stay in the work area.
Established infestations
Large mats may need repeated cutting or pulling before fruit develops. Where manual work is impractical, a qualified applicator can assess a labeled treatment that protects desirable vegetation. Ask local Extension about any reporting or biological control programs.
Keep it from coming back
Return during the growing season to catch later seedlings. Check disturbed edges and places where fruit could have washed or been carried. Maintain cover from desirable plants as the infestation recedes.
Check local requirements
Before moving plant material, working near water or using an herbicide, check the rules for your property. Use only products labeled for the plant and site, and follow the label. Ask the local authority about disposal.

Common questions
If it dies in winter, why remove it?
The vine is annual, but seed can remain in the soil. Stopping fruit production reduces the number of seeds that can start the next generation.
Ask ArborActive about your property
Send your town, the approximate patch size and a photo of the suspected mile-a-minute vine. Mention nearby water and plants you want to keep.
