Ground elder (Aegopodium podagraria), also known as bishop’s weed, is a notoriously invasive perennial that spreads rapidly through underground rhizomes. Its aggressive nature makes it difficult to control using mechanical methods alone. To effectively manage and eliminate ground elder, you need herbicides that penetrate both the foliage and root systems.
Ground elder Herbicide has been selected based on effectiveness, user experience, and ability to handle dense, persistent patches of this weed.
Whether you want organic solutions or commercial-grade strength, there is a wide range of Ground elder Herbicides to suit your needs.
This comprehensive guide outlines the best herbicides for targeting ground elder in various settings, from lawns to flower beds and borders. Let’s dive into the best options available today.
10 Best Herbicides for Ground Elder
1. Roundup Pro Concentrate
Roundup Pro is a professional-grade systemic herbicide that effectively eliminates ground elder by killing it to the root. Its glyphosate-based formula is absorbed through the leaves and translocated down into the rhizomes. It’s rainfast within 2 hours and shows visible results in 7–10 days.
Apply during active growth when ground elder has fully leafed out. Use a tank sprayer for best results in dense infestations. Avoid contact with ornamental plants as it is non-selective.
This is ideal for clearing large areas or unmanaged gardens taken over by ground elder. Always wear protective gear when applying. It’s a powerful solution for long-term control.
2. Ortho GroundClear Vegetation Killer
Ortho GroundClear uses glyphosate and imazapyr to eliminate ground elder and prevent regrowth for up to a year. It offers both contact and residual weed control. It’s suitable for driveways, patios, and non-crop areas where total clearance is desired.
Spray directly onto fully emerged ground elder leaves for optimal absorption. It begins working in 3 hours and fully kills the plant within 2 weeks. Avoid using near trees or shrubs due to soil mobility of imazapyr.
This is a great option for areas where no vegetation is wanted. It’s fast-acting, effective, and long-lasting. Do not use on or near lawns.

Buyer’s Tips for Choosing Herbicide for Ground Elder
1. Choose a Systemic Herbicide for Ground Elder
Ground Elder spreads aggressively through underground rhizomes, making systemic herbicides essential for complete control. These herbicides are absorbed by Ground Elder’s leaves and travel deep into its root system, killing the entire plant—not just the visible parts. Look for ingredients like glyphosate or triclopyr that are proven effective against Ground Elder.
2. Look for Root-Killing Formulas That Target Ground Elder
To fully eliminate Ground Elder, select herbicides labeled as “kills Ground Elder to the root.” This invasive weed is known for regrowing quickly after surface damage, so avoid contact-only sprays. Always choose a formulation designed to destroy Ground Elder’s root network completely.
3. Use a Strong Concentration to Tackle Ground Elder
Ground Elder is a tough perennial that often requires high-concentration herbicides for successful eradication. Products with glyphosate concentrations of 360g/L or more are typically more effective on mature Ground Elder infestations. Follow label instructions closely to ensure proper dosage for Ground Elder control.
4. Choose the Right Herbicide Formulation for Ground Elder Areas
Depending on the location of the infestation, the best herbicide for Ground Elder might be a ready-to-use spray, concentrate, or gel applicator. For Ground Elder in flower beds, a gel or brush-on product allows precise targeting without harming nearby plants. For widespread Ground Elder infestations, concentrated solutions offer better coverage and value.
5. Select a Herbicide Safe for Soil Reuse After Ground Elder Treatment
After treating Ground Elder, many gardeners plan to replant the area. Choose a herbicide that breaks down quickly in the soil to avoid harming future plantings. Glyphosate is a popular choice for Ground Elder because it becomes inactive on contact with soil, making it ideal for vegetable gardens and ornamental beds.
6. Pick Herbicides That Are Garden-Friendly for Ground Elder Removal
Ground Elder often invades areas near shrubs, perennials, and vegetables. Look for herbicides labeled as safe to use around garden plants while targeting Ground Elder. Products with shielded sprayers or applicator sticks help minimize drift and protect non-target species when removing Ground Elder from delicate spots.
7. Ensure the Herbicide Is Rainfast to Maximize Ground Elder Control
Because Ground Elder thrives in damp, shaded environments, choose a herbicide that becomes rainfast within 1–2 hours. Fast-drying formulas ensure that the treatment remains effective even if rain or irrigation follows shortly after application. This prevents Ground Elder from surviving due to herbicide wash-off
Ground Elder Herbicides FAQs
1. What is the best herbicide for killing Ground Elder permanently?
The best herbicide for permanently killing Ground Elder is one that contains glyphosate or triclopyr as the active ingredient. These systemic herbicides penetrate the leaves and travel down to the roots, effectively killing the entire plant and preventing regrowth. Look for products labeled specifically for tough perennials and deep-rooted weeds like Ground Elder.
2. Can I use a selective herbicide to target Ground Elder without harming grass?
Yes, but with caution. Some selective herbicides are designed to kill broadleaf weeds like Ground Elder without damaging grasses. However, Ground Elder’s underground rhizomes make it tough to eliminate with selectives alone. For complete control, especially in non-lawn areas, non-selective systemic herbicides are more effective.
3. When is the best time to apply herbicide on Ground Elder?
The most effective time to apply herbicide on Ground Elder is late spring through early summer when the plant is in full leaf and actively growing. Applying during this phase allows the herbicide to be fully absorbed and translocated to the root system, increasing the chances of full eradication.
4. How many applications are needed to kill Ground Elder completely?
Ground Elder is very persistent and often requires multiple applications of herbicide for full control. Typically, 2–3 treatments spaced a few weeks apart will significantly weaken and eventually kill the plant. Be sure to reapply if you notice new growth emerging from the soil.
5. Are organic herbicides effective against Ground Elder?
Organic herbicides made with natural acids or oils may burn the top growth but usually don’t kill Ground Elder’s deep, spreading roots. For long-term control, chemical herbicides with systemic action are far more effective. Use organic solutions only for temporary suppression or in areas where chemical use is restricted.
6. Can I apply herbicide to Ground Elder in flower beds or around crops?
Applying herbicide near sensitive plants requires precision. Use a shielded sprayer or paint-on method to avoid contact with ornamentals or crops. Alternatively, look for spot treatment herbicides safe for garden use and always read the label for crop and flower bed compatibility.
7. How do I prevent Ground Elder from coming back after herbicide treatment?
After killing Ground Elder with herbicide, prevent its return by removing all root fragments, covering the area with mulch or landscape fabric, and monitoring for regrowth. Reapply herbicide immediately at the first sign of new shoots. Consistent follow-up is key to keeping Ground Elder out permanently
Conclusion
Ground elder is one of the toughest weeds to control, but with the right herbicide and application timing, long-term elimination is possible. Using systemic products that penetrate to the roots is key to avoiding regrowth. Triclopyr, glyphosate, and 2,4-D are among the best ingredients for full control.
Choose your herbicide based on where you’re applying it—lawns, flower beds, or non-crop zones—and always follow label instructions. By combining chemical control with good lawn care practices, you can reclaim your garden from ground elder for good. Take action early and persist for lasting results.
