Because porcelain-berry vines can grow up to 15 feet in a single growing season, especially when rainfall is abundant, and seed may be viable in the soil for several years, effective control requires dedicated follow-up. Treatment measures often must be repeated during the growing season and for several years afterwards to fully eradicate the plant. Prevention of flowering, fruiting, and seed production will help reduce its spread.
Hand pulling of vines in the fall or spring will prevent flower buds from forming the following season. Where feasible, plants should be pulled up by hand before fruiting to prevent the production and dispersal of seeds. If the plants are pulled while in fruit, the fruits should be bagged or disposed of at the town composting facility. The 'cut-and-dab' herbicide method may be useful in deterring more profaned growth. Foliar spray is not recommended as it can be harmful to the surrounding floura and fauna. See the invasive removal page
for how to carry out these methods. Any removal within 100 feet of wetland resource areas, including certified vernal pools, or within 200 feet of a perennial stream may require approval from the Concord Natural Resources Commission. Please contact the Division of Natural Resources before you begin.
