Creeping Jenny Control: How to Keep This Invasive Plant in Check
If you’re a gardener or landscaper, you may be familiar with the creeping jenny plant. Also known as Lysimachia nummularia, this fast-growing groundcover can quickly take over your garden or lawn if left unchecked. While creeping jenny can be an attractive addition to your landscape, it’s important to know how to control its growth to prevent it from becoming invasive.
What is Creeping Jenny?
Creeping jenny is a low-growing perennial plant that is native to Europe and western Asia. It is often used as a groundcover because of its rapid growth and ability to spread quickly. The plant has small, round leaves that are bright green in color and grow on thin, wiry stems.
Why is Creeping Jenny Invasive?
The main reason why creeping jenny can become invasive is because of its aggressive growth habit. The plant spreads by rooting at nodes along its stems, which allows it to quickly cover large areas of soil. In addition, creeping jenny is able to tolerate a wide range of growing conditions, from full sun to partial shade and moist to dry soils.
How to Control Creeping Jenny
If you want to keep creeping jenny under control in your garden or lawn, there are several strategies you can use:
Hand Pulling
One of the simplest methods of controlling creeping jenny is to hand pull it. This method involves removing the plant and its roots by hand, which can be time-consuming but effective for small infestations. To make hand pulling easier, it’s best to do it after a rainfall when the soil is moist.
Smothering with Mulch
Another way to control creeping jenny is to smother it with mulch. This method involves covering the plant with a thick layer of mulch, which will prevent it from getting the sunlight it needs to grow. Over time, the creeping jenny will weaken and die off. However, this method may not be effective for large infestations.
Chemical Control
If hand pulling and smothering with mulch don’t work, you may need to resort to chemical control methods. There are several herbicides on the market that are effective against creeping jenny, but it’s important to choose one that is safe for your other plants and follow the label instructions carefully. Glyphosate-based herbicides are commonly used to control creeping jenny, but they may also harm other plants in your garden.
Prevention
The best way to control creeping jenny is to prevent it from spreading in the first place. If you’re planning to use creeping jenny as a groundcover, be sure to plant it in a contained area or use barriers to prevent it from spreading. It’s also important to monitor your garden regularly and remove any creeping jenny plants before they have a chance to spread.
While creeping jenny can be a beautiful addition to your garden, it’s important to know how to control its growth to prevent it from becoming invasive. Hand pulling, smothering with mulch, and chemical control are all effective strategies for controlling creeping jenny, but prevention is always the best option. By planting creeping jenny in a contained area and monitoring your garden regularly, you can keep this invasive plant in check and maintain a beautiful and healthy landscape.
