How to Control Porcelain Berry in CT, MA & RI
By ArborActive Team · Updated
Porcelain berry can cover a shrub in a thick mat. Identify it before removing vines that could be native grapes.
Identify the plant
Ampelopsis glandulosa var. brevipedunculata. Look for toothed, often lobed leaves and berries that can turn turquoise, purple or pale green. The pith inside the stem is white. Native grape vines typically have brown pith and older bark that peels or shreds.

Start with the size of the patch, what you want to preserve and whether the site is near water.
Small patches
Pull young plants when roots come free easily. Where a vine is fruiting, collect the fruit as stems are removed. Start with isolated plants before the patch grows into nearby trees or shrubs.
Established infestations
Cut accessible stems to release covered plants and dig out roots where disturbance is acceptable. Large patches can resprout from established roots. A qualified applicator may selectively treat new foliage or use another label-approved method suited to the stem and site.
Keep it from coming back
Recheck openings after cutting. Both seedlings and shoots from surviving roots can appear. Retain desirable plants and restore cover where the vine left bare ground.
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
Can berry color alone identify it?
Color helps when fruit is present, but leaves and stems provide useful confirmation. Compare the stem pith and bark before treating a vine that resembles grape.
Ask ArborActive about your property
Send your town, the approximate patch size and a photo of the suspected porcelain berry. Mention nearby water and plants you want to keep.
