Dig and remove the roots of old man’s beard vines. The roots grow deep into the soil and are difficult to remove. Remove as much of the root ball as possible.

Tips for Removing Old Man’s Beard

Cut vines with loppers or a machete. Dig out the root crown with picks, shovels, or similar tools.
Digging out plants is easiest when the soil is moist.
Dispose of them in the green waste bin or trash. Old man’s beard can resprout from stems that touch the ground. If you compost it in place, lay a tarp or sheet of cardboard under piles of stems to prevent them from developing roots.
Cut vines growing on trees and shrubs at roughly waist height. Leave the vines and foliage in the canopy. The cut vines will die. Then either dig out the root or treat the stem with herbicide as described below.

Soil Disturbance and Erosion

Minimize soil disturbance as much as possible when removing old man’s beard.
Regrade the soil after digging ivy roots. Apply mulch (when appropriate).
Take steps to prevent erosion as needed.
Replant the area to shade old man’s beard seedlings.

Herbicides Triclopyr & Glyphosate

Chemical Method: Use with caution

Herbicides Triclopyr & Glyphosate

Use if Necessary

Herbicides that contain the active ingredients triclopyr and glyphosate effectively control old man’s beard when used according to label directions.

Does it work?	Effective Several years of monitoring and effort are required to get rid of old man’s beard. Use preventive measures for best results.
How much effort?	Moderate effort Treat individual old man’s beard plants and patches. Return to the area each year and take action as needed.
What's the risk?	Moderate risk Herbicides come with real risks. ALWAYS read the entire label front to back. Review instructions even for brands you know. Herbicides can run off your site into waterways and may harm wildlife. See How to Keep Pesticides Out of Waterways.
Possible risk of exposure or harm from chemicals	Using herbicides includes some amount of risk. The lowest risk comes with using alternative methods. You may be exposed to an herbicide if you: Get it on your skin Breathe it in Eat or smoke afterward without washing hands Touch or eat plants that are wet with spray (you, pets, or children) Bring it inside on your shoes or clothes Follow directions closely to reduce risk.

Herbicides with active ingredients triclopyr and/or glyphosate, used individually or in a mixture, are effective chemical treatments for old man’s beard. Look for these chemical names in the “Active Ingredients” section of product labels.

The white box on the example product label highlights active ingredient triclopyr. The text on the label states “Kills completely – stumps and roots won’t grow.”
Triclopyr doesn’t injure most grasses. It is a good choice for treating old man’s beard growing next to desired grasses in lawn, pasture, and meadow areas.
Triclopyr is more effective than glyphosate if the herbicide is applied to leaves.

The white box on the example label highlights active ingredient glyphosate. Text on the label states “Kills grass and weeds around flower beds, trees, shrubs....”
Glyphosate will damage most plants and grasses. Don’t let the spray contact plants you wish to keep.

Herbicide Application Tips

Premixed products are available in hardware stores and garden centers.
Old man’s beard often grows with other desired plants, which makes it difficult to treat the foliage, especially for large plants climbing up other vegetation.
Cut-stump and basal-bark applications are common herbicide techniques for this invasive vine. See below.
Apply herbicide to old man’s beard when it is actively growing (late spring through early fall in the Pacific Northwest).
Glyphosate is most effective on this plant in September and early October. Triclopyr can be used earlier in the year.
Don’t treat old man’s beard foliage with herbicide when it is flowering. The flowers shield the foliage and make the herbicide application less effective.
Return to the treated area and look for regrowth and re-treat every year, if needed.

Common Herbicide Application Techniques for Old Man’s Beard

Diagram of basal bark herbicide application technique

James H. Miller, USDA Forest Service, Bugwood.org

Basal-Bark Application

This approach works best for stems that are less than 6 inches in diameter.
Concentrated herbicide (oil soluble) is mixed with another ingredient (adjuvant); typically, a seed oil.
The mixture is sprayed on stems from the ground to a height of 12–18 inches.
The plant absorbs the herbicide sprayed on the trunk. The herbicide moves to the roots.

Cut-Stump Application

Cut stems as close to the ground level as possible.
Remove sawdust and debris from the cut.
Apply concentrated herbicide to the area just inside the bark. This area has living tissue (cambium) that will transport the herbicide to the roots.
Apply herbicide as soon as possible after cutting the stem.
For cut-stump applications, triclopyr is more effective during the early summer. Glyphosate is more effective when applied from mid-summer to leaf fall.

They have detailed information on how to use the product correctly and legally.
They contain information on potential hazards of the product.
They provide instructions you should follow for poisonings and spills.
Following label instructions helps you to minimize the risks and maximize the benefits.

Key Herbicide Safety Tips

Read the entire label front to back.
Follow the instructions.
Review the instructions even for brands you know.
Only apply the product where the label says it may be applied.
Be precise in your application. More is not better.

The Label is the Law

ALWAYS read the label before using herbicide products. The label is a legal document that provides information on how to safely use the herbicide. This helps avoid harm to human health and the environment. Using an herbicide in off-label ways is illegal. It can result in legal enforcement actions.

READ THE LABEL & Follow Instructions
It has instructions to protect you and the environment.

Labels are different for every product and they often change over time.
Use a magnifying glass if needed.
Pay attention to CAUTION, WARNING, and DANGER statements.
Pay attention to the PRECAUTIONARY STATEMENTS.
The law states you must read and follow herbicide instructions.

Protect Yourself
Eye, skin & lung irritants

Wear the right protective gear. This often includes chemical-resistant gloves, safety glasses, a long-sleeve shirt, pants, socks, and shoes.
Mix outdoors or in a well-ventilated area.
Wash hands after mixing or applying, and before eating or smoking.
Take a shower immediately after handling herbicides.
Wash clothes worn while mixing or applying separately from other laundry.

Keep them away during and after applying herbicides (read label for how long).
Remove toys and pet dishes from yard before applying.
Don’t track herbicide products into your home on shoes or clothes.

Protect Plants You Want to Keep

Glyphosate and similar herbicide ingredients damage both grass and broadleaf plants.
Minimize spraying of foliage, stems, exposed roots, or the trunks of desirable shrubs or trees to avoid harm.
Follow the label to avoid damaging the roots of trees and shrubs.

Avoid Wet, Windy, or Hot Weather
Use during favorable weather for best results.

Don’t spray when it’s raining or when rain is expected in the next 24 hours.
Wind causes spray to drift that can get on you and desired plants.
Herbicides may be less effective in hot weather if the target plants are moisture-stressed.
Some herbicides can turn into a vapor in hot weather and damage nearby plants.

Protect Pollinators

Apply in the early morning or evening when bees are less active.
Kill weeds before they flower. Avoid spraying flowering plants.
Do not spray on bees or insects.

Storage & Disposal

Store in a secure area away from children.
Don’t put unused herbicide products in the trash.
