Advice on prevention and control:

Posted 2/22/14 by Kathleen Nelson, Mad Gardeners’ Mile-a-Minute Control Project

PLEASE CHECK YOUR PROPERTY FOR PERSICARIA PERFOLIATA, MILE-A-MINUTE VINE (MAM). Yearly checks plus timely action can prevent MAM from becoming a serious pest on your property. See the video at for help recognizing the plant.

Mile-a-Minute Vine, an invasive annual vine from Asia, is being found in more and more places in New England. Expect it to arrive at your property soon. MAM usually arrives in new places in soils that contain MAM seeds. Once arrived, birds and other animals carry seeds to nearby properties. Be prepared to take immediate action to prevent establishment of new patches. A single seed arriving at a new place can, within 4-5 years, give rise to a large, dense patch covering all other vegetation and producing hundreds of thousands of seeds each year plus satellite patches as far as a mile away.


PREVENTION: MAM arriving from a distance often comes in with soil—perhaps a seed in bulk soil, on the soil of a potted plant, on the tires of equipment—even on shoes.

Spotted Lanternfly Confirmed in Pennsylvania

Please see the Pest Alert and follow this link for information regarding the Spotted Lanternfly, a new insect pest recently confirmed in Pennsylvania, the first detection in the US. The Spotted Lanternfly is a planthopper native to Asia that attacks numerous hosts, including grapes, fruit trees, pines, and more than 70 other species. In the fall, adults can be found on the invasive plant Tree-of-heaven (Ailanthus altissima).

You may already have heard about Asian Mile-a-Minute Vine, (MAM), which was accidentally introduced into Pennsylvania, and is rapidly moving north, smothering fields, meadows, and woodland edges. An annual that can grow six inches a day, it blankets everything, blocking other plants’ light. Only tall trees may survive.

The invasion front is moving north. Four populations have been found in southern Litchfield County. The only way to stop this serious threat to New England's agriculture and environment is to prevent the spread of seeds....

how you can help

posted 9/24/14 from New Milford, CT

Start by educating yourself. View and printout information on Mile-A-Minute from this web site. Get to know how to identify this invasive plant by its triangular leaves and tiny barbs on weak stems clambering over trees and shrubs.

Check your own backyard. When you are gardening, walking, hiking, visiting — be aware and look for signs of invasive plants.

Rely on experts. If you suspect Mile-A-Minute Vine, report it. Somebody will contact you to verify the identification.

Please REPORT ALL SIGHTINGS to or or or The Connecticut Invasive Plant Working Group at 860-486-6448.

We need volunteers to contact property owners and help check properties. Contact: Kathleen Nelson, or 860-355-1547.

Be on the Lookout for Mile-a Minute Vine!

posted 9/24/14 from New Milford, CT

Mile-a-Minute Vine (Persicaria perfoliata formerly Polygonum perfoliatum), an invasive Asian annual weed accidentally introduced from Asia into Pennsylvania, has been moving steadily northward. Until recently, the northern front of the invasion was southern New York State and southwestern Connecticut. In 2004 and 2005, populations were discovered in New Milford and Bridgewater, Connecticut. In 2007 two large populations were discovered in Newtown....
