Weed control is a critical aspect of lawn care, and numerous products are available on the market to help homeowners and gardeners achieve a weed-free lawn. One of the most popular products for weed control is Scotts Bonus, a herbicide designed to selectively kill weeds without harming the surrounding grass. However, the effectiveness of Scotts Bonus can vary depending on several factors, including the type of weeds, the application rate, and the environmental conditions. In this article, we will delve into the details of how long it takes for Scotts Bonus to kill weeds and provide valuable insights into the product’s mode of action, application guidelines, and tips for optimal results.
Understanding Scotts Bonus and Its Mode of Action
Scotts Bonus is a post-emergence herbicide, which means it is applied to weeds that have already germinated and are actively growing. The product contains a combination of active ingredients, including dicamba and mecoprop, which work together to control a wide range of broadleaf weeds, including dandelions, clover, and plantain. The mode of action of Scotts Bonus involves the inhibition of cell growth and division in susceptible weeds, ultimately leading to the death of the plant.
The Importance of Proper Application
To achieve optimal results with Scotts Bonus, it is essential to follow the recommended application guidelines. This includes applying the product at the correct rate, using the right type of sprayer, and spraying the weeds at the optimal growth stage. The label instructions should be carefully read and followed to ensure safe and effective application. Proper application is critical to avoid damaging the surrounding grass or other desirable plants.
Environmental Factors Affecting Scotts Bonus Efficacy
Several environmental factors can influence the efficacy of Scotts Bonus, including temperature, humidity, and soil moisture. For example, high temperatures and dry soil conditions can reduce the product’s effectiveness, while cool and moist conditions can enhance its activity. It is also important to avoid applying Scotts Bonus during periods of extreme weather, such as heavy rain or intense sunlight, as this can affect the product’s absorption and translocation in the weed.
How Long Does Scotts Bonus Take to Kill Weeds?
The length of time it takes for Scotts Bonus to kill weeds can vary depending on the factors mentioned earlier. Generally, visible results can be seen within 7-14 days after application, with the weeds turning yellow or white and beginning to die. However, the complete death of the weeds may take several weeks, typically within 4-6 weeks after application. It is essential to be patient and allow the product to work its way through the weed’s system, as premature mowing or disturbance of the treated area can reduce the product’s effectiveness.
Factors Influencing the Speed of Weed Control
Several factors can influence the speed of weed control with Scotts Bonus, including the type and size of the weeds, the application rate, and the environmental conditions. For example, larger weeds may require higher application rates or repeated applications to achieve complete control, while smaller weeds may be controlled more quickly. Additionally, weeds that are under stress due to drought or other environmental factors may be more susceptible to the product.
Weed Size and Type
The size and type of weeds can play a significant role in determining the speed of control with Scotts Bonus. Larger weeds, such as perennial broadleaf weeds, may require higher application rates or repeated applications to achieve complete control. On the other hand, smaller weeds, such as annual broadleaf weeds, may be controlled more quickly. The type of weed is also an important factor, as some weeds may be more resistant to the product than others.
Best Practices for Using Scotts Bonus
To achieve optimal results with Scotts Bonus, it is essential to follow best practices for application and use. This includes:
- Reading and following the label instructions carefully
- Applying the product at the correct rate and using the right type of sprayer
- Spraying the weeds at the optimal growth stage
- Avoiding application during periods of extreme weather
- Allowing the product to work its way through the weed’s system before mowing or disturbing the treated area
Maintenance and Follow-Up
After applying Scotts Bonus, it is essential to maintain the treated area to prevent re-growth of weeds. This includes regular mowing, watering, and fertilization to promote healthy grass growth. Additionally, follow-up applications may be necessary to control new weeds that germinate after the initial application. By following these best practices and maintaining the treated area, homeowners and gardeners can achieve a weed-free lawn and enjoy a healthy and thriving grass.
Conclusion
Scotts Bonus is a popular and effective herbicide for controlling broadleaf weeds in lawns. While the product can take several weeks to achieve complete control, visible results can be seen within 7-14 days after application. By following the recommended application guidelines, taking into account environmental factors, and maintaining the treated area, homeowners and gardeners can achieve optimal results with Scotts Bonus. Remember to always read and follow the label instructions carefully and take necessary precautions to avoid damaging the surrounding grass or other desirable plants. With patience and proper use, Scotts Bonus can be a valuable tool in achieving a weed-free lawn.
What is Scotts Bonus S and how does it work?
Scotts Bonus S is a type of herbicide designed to control weeds in lawns. It contains a combination of active ingredients, including dicamba and mecoprop, which work together to target and eliminate weeds. The product is typically applied as a spray or granule, and it can be used on a variety of grass types, including Kentucky bluegrass, perennial ryegrass, and tall fescue. When applied correctly, Scotts Bonus S can be an effective tool for maintaining a healthy, weed-free lawn.
The exact mechanism of action for Scotts Bonus S involves the inhibition of plant growth regulators, which ultimately leads to the death of the targeted weeds. The dicamba in the product works by mimicking the plant hormone auxin, causing the weeds to grow abnormally and eventually die. The mecoprop, on the other hand, inhibits the production of chlorophyll, which is essential for photosynthesis. By combining these two active ingredients, Scotts Bonus S is able to provide broad-spectrum weed control, targeting a wide range of weed species, including dandelions, clover, and plantain.
How long does it take for Scotts Bonus S to start killing weeds?
The time it takes for Scotts Bonus S to start killing weeds can vary depending on several factors, including the type and size of the weeds, the temperature and humidity, and the application rate. In general, however, users can expect to start seeing results within 7-14 days after application. During this time, the weeds may begin to show signs of stress, such as yellowing or browning of the leaves, and they may start to die back. It’s essential to note that the product may not kill weeds immediately, but rather, it will take some time for the active ingredients to take effect.
After the initial application, it’s recommended to wait at least 2-3 weeks before reapplying the product. This allows the active ingredients to fully take effect and ensures that the weeds are completely eliminated. Additionally, it’s crucial to follow the instructions on the label and apply the product at the recommended rate to avoid under- or over-application. By following these guidelines, users can maximize the effectiveness of Scotts Bonus S and achieve optimal weed control.
Is Scotts Bonus S safe for use on all types of lawns?
While Scotts Bonus S is generally considered safe for use on most types of lawns, it’s essential to read the label carefully and follow the instructions to ensure safe and effective application. The product is not recommended for use on certain types of grass, such as St. Augustinegrass, Bermudagrass, or zoysiagrass, as it may cause damage or discoloration. Additionally, users should avoid applying the product to lawns that are under stress, such as those that are suffering from drought or disease, as this can increase the risk of adverse effects.
Before applying Scotts Bonus S, users should also take steps to prepare their lawn, such as mowing the grass to the recommended height and removing any debris or clutter. It’s also essential to water the lawn thoroughly after application to help the active ingredients reach the roots of the weeds. By taking these precautions and following the instructions on the label, users can minimize the risk of adverse effects and ensure safe and effective use of the product.
Can Scotts Bonus S be used in combination with other lawn care products?
In general, Scotts Bonus S can be used in combination with other lawn care products, but it’s essential to read the label carefully and follow the instructions to ensure safe and effective application. The product can be used with fertilizers, for example, to provide a comprehensive lawn care program that addresses both weed control and nutrient needs. However, users should avoid combining Scotts Bonus S with other herbicides or pesticides, as this can increase the risk of adverse effects or reduce the effectiveness of the product.
When using Scotts Bonus S in combination with other products, users should follow the recommended application rates and schedules to minimize the risk of overlap or interference. It’s also essential to choose products that are compatible with Scotts Bonus S and that are suitable for use on the same type of grass. By taking these precautions and following the instructions on the label, users can create a comprehensive lawn care program that addresses a range of needs and provides optimal results.
How long does Scotts Bonus S take to kill weeds completely?
The time it takes for Scotts Bonus S to kill weeds completely can vary depending on several factors, including the type and size of the weeds, the temperature and humidity, and the application rate.

After the weeds have been eliminated, users can take steps to prevent regrowth, such as maintaining good lawn care practices, including regular mowing, watering, and fertilization. Additionally, users can apply a pre-emergent herbicide in the spring to prevent new weeds from germinating. By following these guidelines and using Scotts Bonus S as directed, users can achieve long-term weed control and maintain a healthy, weed-free lawn.

Can I use Scotts Bonus S to control weeds in garden beds or other non-lawn areas?
No, Scotts Bonus S is specifically designed for use on lawns and should not be used to control weeds in garden beds or other non-lawn areas. The product contains active ingredients that are specifically formulated to target weeds in lawns, and using it in other areas can result in damage to desirable plants or other unintended consequences.
