Creeping Jenny, also known as Lysimachia nummularia ‘Aurea,’ is a fast-spreading, golden-leaved groundcover that can be both a blessing and a curse for lawn enthusiasts. While it can add a touch of warmth and vibrancy to your outdoor space, it can also quickly overtake other plants, becoming a nuisance that’s difficult to control. If you’re struggling to keep Creeping Jenny under wraps, don’t worry – we’ve got you covered. In this article, we’ll delve into the world of Creeping Jenny control, exploring 12+ ways to keep this feisty groundcover in check and maintain a perfect lawn.
Understanding Creeping Jenny
Before we dive into the control methods, it’s essential to understand the nature of Creeping Jenny. This perennial plant is known for its rapid growth, producing long stems that root at the nodes, allowing it to spread quickly. It thrives in moist, well-drained soil and partial shade to full sun, making it a challenging plant to eradicate once it’s taken hold. Creeping Jenny can be beneficial as a groundcover, helping to suppress weeds and add visual interest to your lawn. However, its aggressive growth can lead to an imbalanced ecosystem, overpowering other plants and creating an eyesore.
1. Physical Removal
One of the most straightforward methods for controlling Creeping Jenny is physical removal. This involves manually pulling or digging up the plant, making sure to remove as much of the root system as possible to prevent regrowth. While this method can be time-consuming, especially for large areas, it’s an effective way to control Creeping Jenny without resorting to chemicals.

2. Mulching
Mulching is another effective method for controlling Creeping Jenny. By applying a thick layer of organic mulch, such as wood chips or bark, you can suppress the growth of the plant by blocking light and preventing seed germination. As the mulch breaks down, it will also improve soil health, making it less conducive to Creeping Jenny growth.
3. Barriers
Installing a physical barrier, such as a landscape edging or a root barrier, can also be an effective way to control Creeping Jenny. These barriers prevent the plant’s creeping stems from spreading into adjacent areas, containing it within a specific boundary. While this method requires an upfront investment, it can provide long-term control with minimal maintenance.
4. Solarization
Solarization involves trapping the sun’s heat under a clear plastic tarp to kill weeds and their seeds. This method is particularly effective for controlling Creeping Jenny, as it can’t tolerate high temperatures. By applying a clear plastic sheet over the affected area and weighing it down with rocks or soil, you can create a mini-greenhouse effect that will kill the plant and its roots.
5. Chemical Control
For larger infestations or more severe cases, chemical control may be necessary. Herbicides specifically designed to target broadleaf weeds can be effective in controlling Creeping Jenny. However, it’s crucial to follow the manufacturer’s instructions carefully and take necessary precautions to avoid damaging other plants or the environment.
6. Companion Planting
Companion planting involves selecting plants that naturally repel or compete with Creeping Jenny, such as creeping thyme or clover. By planting these species in close proximity, you can create a balanced ecosystem that suppresses the growth of Creeping Jenny. This method requires some planning and research but can be an effective, chemical-free control strategy.
7. Mowing and Trimming
Regular mowing and trimming can also help control Creeping Jenny. By maintaining your lawn at a height that prevents the plant from flowering and setting seed, you can reduce its spread. Additionally, trimming back the stems regularly can weaken the plant, making it more susceptible to other control methods.
8. Soil Improvement
Creeping Jenny thrives in poor soil conditions, so improving soil health can be an effective way to control its growth. By adding organic matter, such as compost or manure, you can create a more balanced soil ecosystem that favors other plants over Creeping Jenny.
9. Groundcover Replacement
If Creeping Jenny has become too aggressive, it may be time to consider replacing it with a less invasive groundcover. Plants like vinca minor or pachysandra are excellent alternatives, offering similar benefits without the risk of overgrowth.
10. Boiling Water
For small, isolated patches of Creeping Jenny, boiling water can be a simple and effective control method. By pouring boiling water directly over the plant, you can kill it without resorting to chemicals. This method requires caution, as boiling water can also damage other plants, so be sure to target the Creeping Jenny specifically.
11. Flame Weeding
Flame weeding involves using a propane torch to apply targeted heat to the plant, killing it without damaging the surrounding soil or plants. This method is particularly effective for controlling Creeping Jenny in tight spaces or where other methods are impractical.
12. Biological Control
Biological control involves introducing natural predators or competitors to control Creeping Jenny. For example, certain species of beneficial nematodes can attack the plant’s roots, weakening it and preventing its spread. While this method requires some research and planning, it can be an effective, long-term control strategy.
Implementing a Control Strategy
Controlling Creeping Jenny effectively requires a combination of these methods, tailored to the specific conditions of your lawn. By understanding the plant’s growth habits and weaknesses, you can develop a comprehensive control strategy that maintains a balance between suppression and eradication.

Conclusion
Creeping Jenny can be a challenging plant to control, but with the right strategies and techniques, you can maintain a perfect lawn. By understanding the plant’s growth habits and weaknesses, you can develop a comprehensive control plan that balances suppression and eradication. Whether you choose physical removal, mulching, or a combination of methods, the key to success lies in persistence and adaptability. Remember to stay vigilant, as Creeping Jenny can quickly regain its foothold if left unchecked.
FAQ Section
What is the most effective way to control Creeping Jenny?
+The most effective way to control Creeping Jenny is through a combination of physical removal, mulching, and regular maintenance, including mowing and trimming. This approach helps to weaken the plant and prevent its spread.
Can I use herbicides to control Creeping Jenny?
+Yes, herbicides can be used to control Creeping Jenny, but it’s essential to follow the manufacturer’s instructions carefully and take necessary precautions to avoid damaging other plants or the environment. It’s also important to note that herbicides should be used as a last resort, as they can have unintended consequences on the ecosystem.
How can I prevent Creeping Jenny from spreading to other areas of my lawn?
+To prevent Creeping Jenny from spreading, it’s essential to remove it completely, including its roots, and improve soil health through the addition of organic matter. Regular mowing and trimming can also help to prevent the plant from flowering and setting seed, reducing its spread.
