How to Apply Weed Killer Effectively and Safely
How to Apply Weed Killer?
To apply weed killer, there are a few key steps to follow.
Firstly, determine which type of weed killer you need – pre-emergent or post-emergent.
Pre-emergent weed killer should be applied in early spring before weeds are visible, while post-emergent weed killer should be applied when weeds are actively growing but before the summer heat arrives.
Next, choose a still, dry day with no rain expected for at least 6 hours to apply the weed killer.
Shake the bottle well before use and mix the required amount of concentrate weed killer with water in a separate watering can or sprayer.
Granular weed killers should be applied when the grass is damp, and not watered for 48 hours after application.
It is advised not to mow the grass before applying the weed killer and to leave it uncut for five days after application.
During drought conditions or for difficult control, a spreader sticker can be added to increase absorption.
Lastly, for convenience, pre-dosed tubes of concentrated weed killer can also be used.
Key Points:
- Determine whether you need pre-emergent or post-emergent weed killer
- Choose a still, dry day with no rain for at least 6 hours
- Shake the bottle well and mix concentrate weed killer with water
- Apply granular weed killer when grass is damp and avoid watering for 48 hours

Did You Know?
1. Did you know that the concept of weed killers dates back to ancient times? The ancient Romans used a mixture of salt and vinegar as a weed killer around their gardens and farmland.
2. In the early 20th century, before the invention of selective herbicides, farmers used to manually remove weeds by hand or through the use of trowels and hoes. This labor-intensive process often required large amounts of manpower.
3. Weed killers are not only used on land but can also be applied in aquatic environments. Aquatic herbicides are specifically formulated to control and eliminate unwanted underwater plants, such as algae and seaweed.
4. The active ingredient in most commercial weed killers is a chemical called glyphosate. However, before its widespread use, other substances such as saltwater, boiling water, and even flaming torches were used to combat weed growth.
5. Using weed killers at the right time of day can significantly improve their effectiveness. Experts recommend applying weed killers in the late afternoon or early evening when the temperature is cooler, as this allows the chemicals to penetrate the weeds more effectively, yielding better results.
Types Of Weed Killers: Pre-Emergent And Post-Emergent
Weed killers are an essential tool for maintaining a healthy and vibrant lawn. Understanding the different types of weed killers and their respective application methods is key to effectively eradicating weeds and promoting the growth of your desired plants.
There are two main types of weed killers: pre-emergent and post-emergent.
-
Pre-emergent weed killers are applied before weeds become visible, typically during early spring. These products create a barrier that prevents weed seed germination, effectively stopping the growth of weeds before they emerge from the soil. It is crucial to apply pre-emergent weed killers before the weeds start to sprout, as they can lose their effectiveness if applied too late.
-
Post-emergent weed killers are used when weeds are actively growing but before the scorching summer heat arrives. These products target the already established weeds and inhibit their growth. Applying post-emergent weed killers before the summer heat sets in ensures optimal effectiveness. It is important to read and follow the manufacturer’s instructions for each product to achieve the best results.
Note: Weed killers should be used in accordance with the manufacturer’s instructions to ensure safe and effective application.

Proper Timing For Weed Killer Application
Timing is critical when it comes to applying weed killers. Whether you are using pre-emergent or post-emergent products, applying them at the right time can significantly enhance their effectiveness.
Pre-emergent weed killers should be applied when the soil temperature reaches a suitable range for weed seed germination. This generally occurs in early spring when the soil temperature reaches around 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius). Applying the weed killer before the weeds germinate ensures that they never have a chance to establish themselves in your lawn.
Post-emergent weed killers, on the other hand, should be applied when the weeds are actively growing. It is best to apply these products before the summer heat intensifies, as high temperatures can stress both the weeds and your lawn. To get the most out of your post-emergent weed killer, ensure the weeds are not under any stress caused by drought or excessive heat.
Applying Granular Weed Killers
Granular weed killers are a popular choice for many homeowners due to their ease of use and effectiveness. When applying granular weed killers, it is crucial to follow the proper procedure to ensure optimal results.
Firstly, choose a dry day for application, with no rain expected for at least 6 hours after treatment. Applying granular weed killers when the grass is damp but not overly wet allows for better product adhesion and absorption, maximizing its efficacy.
Before applying the weed killer, it is advised not to mow the grass. Leaving the grass uncut for five days after application gives the product ample time to work its way into the weeds and promote their elimination. Remember to follow the specific instructions on the package for the waiting period specific to the product you are using.
Lawn Care Tips For Weed Killer Application
In addition to proper timing and application techniques, certain lawn care practices can further enhance the effectiveness of weed killers. Gertens, a renowned expert in lawn care, offers a 4-step program that, when followed diligently, can help keep your lawn weed-free and beautiful.
-
Firstly, it is crucial to have a steady and consistent lawn maintenance routine. Regular mowing, watering, and fertilizing will aid in creating a strong and healthy lawn that is less prone to weed growth. Avoiding excessive thatch buildup, by raking or dethatching your lawn, also helps provide a more conducive environment for your grass to flourish.
-
Secondly, it is essential to choose the right type of weed killer for your specific lawn conditions and weed problems. Taking into account factors such as the type of weeds, climate, and grass variety can help in selecting the most effective product for your lawn.
-
Lastly, it is recommended to follow the manufacturer’s instructions carefully when applying the weed killer. Shake the bottle well before use to ensure proper mixing of the ingredients and achieve an even application. Using a separate watering can or sprayer solely for weed killer application prevents any potential cross-contamination and helps maintain the effectiveness of the product.
-
Remember, proper lawn care practices combined with the use of effective weed killers can help you achieve a weed-free and beautiful lawn.
Enhancing Weed Killer Absorption
During drought conditions or when weed control becomes challenging, a spreader sticker can be added to the weed killer mix to enhance absorption. A spreader sticker acts as an agent to improve the weed killer’s adherence to the leaves and overall absorption by the plant.
Spreader stickers are particularly useful when dealing with hard-to-kill weeds or when environmental conditions hinder proper product absorption. Using a spreader sticker allows for more efficient use of the weed killer, reducing the need for repeated applications and potentially saving money in the long run.

Frequently Asked Questions
What is the best time to spray weed killer?
The optimal timing to spray weed killer largely depends on weather conditions and the specific herbicide brand being used. Ideally, one should consider spraying weed killer 30 minutes to an hour prior to rainfall, provided that the brand allows it. By doing so, the rain can help activate and distribute the herbicide effectively. However, it is crucial to ensure that the leaves are dry before applying the spray after rainfall to prevent the herbicide from being washed away. Therefore, a careful balance between timing the spray before rain and waiting for the leaves to dry is key in achieving the best results when using weed killer.
How many times should I apply weed killer?
To effectively combat weed growth, it is recommended to apply weed killer at least twice a year. As no weed killer offers a permanent solution, this periodic approach allows for continued suppression of weed growth. By consistently applying weed killer throughout the year, you can ensure that the weeds are kept at bay and minimize their chances of regrowth. Remember, persistence is key in maintaining a weed-free environment.
How long does weed killer last?
The longevity of weed killer depends on multiple factors, including the specific type of herbicide used and its concentration in the soil. Persistent herbicides can persist for varying durations, ranging from a month to several years before fully breaking down into inactive compounds. Therefore, it is important to consider the specific herbicide being used and its concentration to determine how long it will last in your soil and continue to control weeds.
Can I spray weeds at night?
Yes, you can spray weeds at night as long as they are not under stress and are actively growing. Despite the importance of good lighting, GPS guidance, and attentive operators, night spraying is deemed acceptable for herbicide uptake, efficacy, and label requirements. It is crucial that the weeds are not experiencing any stress and are actively growing before entering the evening.
