Bindweed, also known as morning glory, is a perennial weed that can quickly overrun a lawn, garden, or landscape. Its twining stems and roots can choke out desirable plants, reducing their growth and productivity. Getting rid of bindweed without killing grass can be challenging, but it is achievable with the right techniques and a bit of patience. In this article, we will explore the most effective methods for controlling bindweed, protecting your grass, and maintaining a healthy and thriving lawn.
Understanding Bindweed
Before we dive into the strategies for eliminating bindweed, it’s essential to understand the characteristics of this pesky weed. Bindweed is a deep-rooted perennial that can grow up to 10 feet tall. Its roots can extend up to 20 feet deep, making it difficult to eradicate. The plant produces small, trumpet-shaped flowers that are usually white or pink, and its leaves are oval-shaped with a pointed tip. Bindweed can spread quickly through its seed pods, which can contain up to 600 seeds. These seeds can remain dormant in the soil for many years, making it crucial to prevent the plant from producing seeds.
Prevention and Cultural Control
Preventing bindweed from taking over your lawn is the best way to avoid the hassle of trying to get rid of it. Here are a few preventive measures you can take:
Bindweed thrives in poor soil conditions, so improving soil fertility and drainage can help prevent its growth. Add organic matter like compost or manure to enrich the soil and promote healthy grass growth. Regularly mowing your lawn at the recommended height for your grass species can also help suppress bindweed growth.
Soil Solarization
Soil solarization is a passive and non-chemical method for controlling weeds, including bindweed. It involves trapping the sun’s heat under a clear plastic tarp or sheeting to kill weeds and their seeds. This method is most effective in warm and sunny climates. To solarize your soil, follow these steps:
- Tr trap the sun’s heat by laying a clear plastic tarp or sheeting over the affected area.
- Bury the edges of the tarp or sheeting with soil to prevent heat from escaping.
- Leave the tarp or sheeting in place for 4-6 weeks during the hottest part of the summer.
- After solarization, remove the tarp or sheeting and plant your desired grass species.
Physical and Mechanical Control
Physical and mechanical control methods involve manually removing bindweed from your lawn. These methods can be time-consuming but are effective for small infestations.
Hand-Pulling and Digging
Hand-pulling and digging are simple and non-chemical methods for removing bindweed. It’s essential to remove as much of the root system as possible to prevent regrowth. Follow these steps:
- Water the soil the day before to make it easier to pull out the roots.
- Use a fork or spade to gently loosen the soil around the bindweed plant.
- Pull out as much of the root system as possible, taking care not to break off any roots.

What is bindweed and how does it affect lawns?
Bindweed is a perennial weed that can be particularly troublesome for lawn owners. It is a climbing plant that can spread quickly, choking out other plants and damaging lawn health. Bindweed has small, trumpet-shaped flowers that are typically white or pink in color, and its stems are slender and twining, allowing it to climb up and over other plants. As bindweed spreads, it can form a dense mat of stems and leaves that can shade out grass and other desirable plants, reducing their growth and overall health.
The impact of bindweed on lawns can be significant, as it can outcompete grass and other plants for water, nutrients, and light. This can lead to a decline in lawn health, causing grass to become thin and weak. Additionally, bindweed can be difficult to eradicate, as its roots can grow deep into the soil and produce new shoots, allowing the plant to regrow even after it has been cut or pulled. Effective strategies for eliminating bindweed are essential to prevent it from taking over a lawn and causing long-term damage. By understanding the habits and growth patterns of bindweed, lawn owners can take targeted steps to control and eliminate this invasive weed.
How does bindweed spread and what are its growth habits?
Bindweed spreads through a combination of seed production and vegetative growth. The plant produces small, egg-shaped seeds that can be dispersed by wind, water, or animals, allowing it to colonize new areas. Additionally, bindweed can spread through its roots, which can produce new shoots and roots as they grow. This allows the plant to form a network of underground stems and roots that can produce new growth, even if the above-ground parts of the plant are removed. Bindweed is also able to regrow from small fragments of root, making it a challenging weed to eradicate.
The growth habits of bindweed are characterized by its ability to twine and climb. The plant’s stems are slender and flexible, allowing it to wrap around other plants and structures. As bindweed grows, it can form a dense mat of stems and leaves that can shade out other plants and reduce their growth. The plant is also able to grow in a variety of conditions, including full sun and partial shade, and can thrive in a range of soil types. By understanding the growth habits of bindweed, lawn owners can develop effective strategies for controlling and eliminating this invasive weed. This may involve a combination of physical removal, herbicides, and cultural controls, such as improving soil health and promoting the growth of desirable plants.
What are the most effective methods for physically removing bindweed?
Physical removal is an important step in controlling bindweed, as it can help to reduce the amount of weed present and prevent it from spreading. The most effective methods for physically removing bindweed involve digging or pulling the plant, taking care to remove as much of the root system as possible. This can be a time-consuming and labor-intensive process, as bindweed roots can grow deep into the soil. It is essential to wear protective clothing, including gloves and eye protection, when removing bindweed, as the plant’s sap can cause skin irritation and eye damage.
To physically remove bindweed, start by cutting the plant back to ground level, using pruning shears or a string trimmer. Then, use a fork or spade to gently loosen the soil around the roots, taking care not to break them. As much of the root system as possible should be removed, as this will help to prevent regrowth. If the roots are deep or extensive, it may be necessary to use a tool such as a root cutter or a garden fork to remove them. After removal, the area should be monitored closely for signs of regrowth, and any new shoots or roots should be removed promptly to prevent the bindweed from re-establishing itself.
Can herbicides be used to control bindweed, and if so, what types are most effective?
Herbicides can be used to control bindweed, but they should be used with caution and in combination with other control methods. The most effective herbicides for controlling bindweed are those that are specifically designed to target broadleaf weeds, such as selective herbicides containing ingredients like dicamba or mecoprop. These herbicides work by selectively killing broadleaf plants, including bindweed, while leaving grass and other desirable plants unharmed. It is essential to follow the label instructions carefully when using herbicides, as they can be hazardous to human health and the environment if not used properly.
When using herbicides to control bindweed, it is essential to apply them at the correct time and in the correct amount. The best time to apply herbicides is when the bindweed is actively growing, typically in the spring or summer. The herbicide should be applied directly to the leaves and stems of the bindweed, taking care to avoid overspray or drift onto desirable plants. It may be necessary to repeat the application several times to achieve effective control, as bindweed can be resistant to herbicides. Additionally, herbicides should be used in combination with other control methods, such as physical removal and cultural controls, to achieve long-term control of bindweed.
How can I prevent bindweed from growing back after removal?
Preventing bindweed from growing back after removal requires a combination of cultural controls and ongoing monitoring. One of the most effective ways to prevent bindweed regrowth is to improve soil health, as bindweed is often able to thrive in poor soil conditions. This can involve adding organic matter, such as compost or manure, to the soil to improve its structure and fertility. Additionally, promoting the growth of desirable plants, such as grass and other lawn species, can help to shade out bindweed and prevent it from regrowing.
Ongoing monitoring is also essential to prevent bindweed regrowth. The area where the bindweed was removed should be checked regularly for signs of new growth, and any shoots or roots that do appear should be removed promptly. This can involve regular mowing, as well as hand-pulling or digging to remove any new bindweed growth. Additionally, using a pre-emergent herbicide in the spring can help to prevent bindweed seeds from germinating, reducing the risk of new growth. By combining these cultural controls and ongoing monitoring, lawn owners can help to prevent bindweed from growing back after removal and maintain a healthy, weed-free lawn.
Are there any alternative methods for controlling bindweed, such as biological control or mulching?
Yes, there are alternative methods for controlling bindweed, including biological control and mulching. Biological control involves using living organisms, such as insects or microorganisms, to control bindweed. For example, the bindweed moth is a natural predator of bindweed that can be introduced to areas where the weed is present. Mulching involves applying a layer of organic material, such as wood chips or straw, to the soil surface to suppress bindweed growth. This can help to prevent light from reaching the bindweed, reducing its ability to photosynthesize and grow.
Mulching can be a particularly effective method for controlling bindweed, as it can help to suppress regrowth and prevent new seedlings from emerging. To use mulching as a control method, apply a thick layer of organic material to the soil surface, taking care to cover all areas where bindweed is present. The mulch should be kept in place for several months to ensure that the bindweed is fully suppressed. Additionally, mulching can help to improve soil health and promote the growth of desirable plants, making it a useful component of an integrated weed management strategy. By combining mulching with other control methods, such as physical removal and herbicides, lawn owners can achieve effective long-term control of bindweed.
