Periwinkle, also known as Vinca minor, is a popular evergreen ground cover known for its blue-purple flowers and its ability to thrive in a variety of conditions. However, it can be invasive and difficult to control, leading many gardeners and homeowners to seek methods for its removal. Removing periwinkle can be a challenging task, but with the right techniques and tools, it is possible to eradicate it effectively. In this article, we will explore the different methods for removing periwinkle, including manual removal, chemical control, and prevention techniques.
Understanding Periwinkle and Its Growth Habits
Before attempting to remove periwinkle, it is essential to understand its growth habits and how it spreads. Periwinkle is a fast-growing, evergreen ground cover that can grow up to 6 inches tall and 12 inches wide. It has long, trailing stems that root at the nodes, allowing it to spread quickly and form dense mats. Periwinkle can thrive in a variety of conditions, including full sun to partial shade and well-drained to moist soils. Its ability to tolerate a range of conditions and its rapid growth rate make it a challenging plant to control.
Manual Removal of Periwinkle
Manual removal is a effective method for controlling small infestations of periwinkle. This method involves physically pulling or digging up the plants, making sure to remove as much of the root system as possible. It is crucial to remove all roots and stems to prevent regrowth. Manual removal can be a time-consuming process, especially for large infestations, but it is a non-invasive and environmentally friendly method.
To manually remove periwinkle, start by cutting the stems back to the ground using pruning shears or a string trimmer. This will make it easier to access the roots and reduce the amount of material that needs to be removed. Next, use a garden fork or shovel to carefully dig up the roots, working in small sections to avoid breaking up the roots and leaving behind pieces that can regrow. It is also essential to remove any rooted nodes, as these can produce new plants.
Chemical Control of Periwinkle
Chemical control is another method for removing periwinkle, especially for large infestations or in areas where manual removal is not practical. Herbicides can be effective in killing periwinkle, but they must be used carefully to avoid damaging other plants or the environment. There are several types of herbicides available, including non-selective and selective herbicides. Non-selective herbicides will kill all vegetation, while selective herbicides target specific plants or plant species.
When using herbicides to control periwinkle, it is essential to follow the instructions on the label carefully and take necessary precautions to avoid exposure. Wear protective clothing, including gloves, long sleeves, and eye protection, and avoid spraying on windy days or when rain is forecasted. It is also crucial to choose an herbicide that is labeled for use on periwinkle and to apply it at the recommended rate.
Prevention Techniques for Periwinkle
Preventing periwinkle from growing in the first place is the most effective method for controlling its spread. There are several techniques that can be used to prevent periwinkle from growing, including using physical barriers, planting competing species, and improving soil health.
Physical Barriers for Periwinkle Control
Physical barriers, such as landscape fabric or plastic sheeting, can be used to prevent periwinkle from growing in specific areas. These barriers work by blocking light and preventing the roots from growing. To be effective, physical barriers must be installed correctly, with the edges buried 6-8 inches deep to prevent the roots from growing underneath.
Planting Competing Species
Planting competing species, such as native grasses or wildflowers, can also be an effective method for preventing periwinkle from growing. These plants compete with periwinkle for resources, such as light, water, and nutrients, making it more difficult for the periwinkle to establish itself. Choose plants that are well-suited to the local climate and soil conditions, and plant them at the same density as the periwinkle.
Soil Improvement for Periwinkle Control
Improving soil health can also help to prevent periwinkle from growing. Periwinkle thrives in poor soil conditions, so improving soil fertility and structure can make it less favorable for the plant. This can be achieved by adding organic matter, such as compost or manure, and using mulch to retain moisture and suppress weeds.
Conclusion
Removing periwinkle can be a challenging task, but with the right techniques and tools, it is possible to eradicate it effectively. Manual removal, chemical control, and prevention techniques can all be used to control periwinkle, depending on the size of the infestation and the desired level of control.

What is Periwinkle and Why is it Considered Invasive?
Periwinkle, also known as Vinca minor, is a type of flowering plant that is native to Europe and Asia. It is a low-growing, evergreen plant that is often used as a ground cover in gardens. However, periwinkle is considered an invasive species in many areas, including North America, because it can quickly spread and outcompete native plants for resources such as water and sunlight. This can lead to a reduction in biodiversity and changes to ecosystem processes.
Periwinkle’s invasive nature is due to its ability to produce long stems that root at the nodes, allowing it to spread quickly and form dense mats. It also produces blue-purple flowers in the spring, which are followed by seed pods that can be dispersed by animals and humans. As a result, periwinkle can be found growing in a variety of habitats, including forests, grasslands, and wetlands. In these areas, it can form dense stands that shade out native plants and prevent them from growing. Removing periwinkle from these areas is necessary to restore native ecosystems and promote biodiversity.
