Controlling Invasive Muscadine Vines on Trees

Identifying and Eradicating Muscadine Grapevines

The vine strangling your trees is muscadine (Vitis rotundifolia), a native grapevine that can become aggressively invasive in landscapes. It climbs trees, smothers canopies, and is difficult to eliminate once established.

Why Muscadine Is a Problem

• Grows rapidly in nutrient-rich soils and along forest edges.
• Highly tolerant of stress, disease, and variable conditions.
• Can girdle and kill trees by blocking light and adding weight.
• Spreads by seeds (birds) and vegetative layering.

Step-by-Step Removal

1. Cut the vine at ground level: Use loppers or a pruning saw to sever the main stem 6 inches above ground. Make a clean, straight cut.
2. Make a second cut (optional): If the vine climbs high, cut again at 5 feet to prevent re-sprouting from the upper stem.
3. Remove the top growth: Pull the severed vine down carefully. If it's too entangled, leave it—it will decay and fall eventually.
4. Treat the stump immediately: Apply concentrated glyphosate (Roundup) directly to the fresh cut surface and any remaining foliage. Use a paintbrush or spray bottle for precision.
5. Monitor and re-treat: Check every 2 weeks during the growing season. Reapply glyphosate to any new sprouts.
6. Follow up next spring: Spot-spray any emerging shoots with glyphosate.

Critical Precautions

• Glyphosate kills ALL green plants it contacts. Avoid drift onto desirable plants, tree leaves, or lawn.
• It's safe to apply to tree bark—just don't get it on foliage.
• Wear gloves, eye protection, and long sleeves.
• Follow all label instructions.

Long-Term Management

Complete eradication may take 2–3 years of vigilance. Prevent re-establishment by removing seedlings promptly and maintaining a mulch ring around trees to discourage vine germination.
