Are you noticing weeds appearing on your lawn? You have a couple of options for dealing with them. You could manually pull out the weeds, which is a safe and effective method. Alternatively, you could use a weed killer to get rid of these unwanted plants. It’s important to note that weed killers, or herbicides, contain chemicals that can be harmful to people, wildlife, and the environment. Before applying herbicides, there are several factors to consider, including the best time of year to do so. Timing is crucial, so knowing when to apply weed killer to your lawn is essential.
We talked to two lawn care experts about the timing of applying weed killer, alternative methods to herbicide use, and the importance of proper lawn maintenance practices such as mowing and watering to prevent weed growth.

When to Apply Weed Killers:
It’s crucial to apply weed killers to your lawn at the right time of year. The type of weed – whether it’s annual or perennial – determines when action should be taken. “Identifying the weed will help you determine when to remove them before they flower and produce seeds,” says Teresa Watkins. For perennial weeds, the best time to apply a weed killer is when the weather starts to cool down after summer. “Fall is the ideal time to control perennial weeds, whether using an organic or chemical-based product,” says John Cannon. This is because plants absorb nutrients differently during this period, making the control products more effective. “In the fall, dormant plants focus on pulling nutrients into their root systems rather than pushing them to the leaves, allowing control products to be absorbed faster into the root zone,” explains Cannon. For annual weeds, spring is the optimal time for control, according to Cannon.
Why You Should Reconsider Weed Killers:
Herbicides contain potent chemicals that can pose risks to humans, animals, insects, and the environment. “Common herbicides like glyphosate-based products such as Round-Up, and those containing 2,4-D, have been linked to cancer in dogs and non-Hodgkin’s lymphoma in children,” warns Cannon. In addition to their toxic nature, herbicides require frequent applications and are not a long-term solution for weed problems. They can contaminate groundwater, lakes, and streams, creating environmental issues. Instead of addressing weed problems, they can lead to the development of pesticide-resistant weeds over time. Choosing healthier and more sustainable weed management practices is advisable to avoid these pitfalls.
Remember that chemicals from herbicides can seep into the soil, so it’s important to use them cautiously and consider alternative methods for weed control.
Your lawn and garden can be impacted by the use of herbicides, which can harm the beneficial organisms in the soil that aid in plant growth. These beneficial organisms, known as ‘good guy organisms,’ play a vital role in reducing issues like turf disease, according to experts like Cannon. Opting for chemical weed killers can lead to bigger problems in your landscape, as overuse can create more challenges. Instead, consider eco-friendly alternatives to protect your lawn, garden, and budget.
Maintaining your lawn is crucial in preventing weed growth. Proper lawn care can effectively prevent weeds without the need for chemicals. By managing your lawn correctly, you decrease the chances of weeds taking root. This approach not only saves you money and time but also promotes a healthy lawn that naturally suppresses weed growth.
Mowing your lawn correctly is essential to its health. Understanding the type of turf and cutting it to the appropriate length can prevent damage and vulnerability. Using a sharp mower blade is key to avoid harming the grass and weakening its structure.
Proper watering is also crucial in weed prevention. Overwatering can lead to shallow root systems in weeds, allowing them to thrive and compete with your grass. Maintaining a healthy root system through correct watering practices is vital for a thriving lawn.
Regularly checking for weeds and addressing them before they become established is a proactive way to prevent weed growth. By monitoring your lawn for unwanted plants and taking action early, you can maintain a beautiful and weed-free landscape.
“Our yard on a weekly basis will help spot the weeds before they take over and a stronger herbicide is warranted,” says Watkins. Mowing the weeds can reduce them from spreading. “If you do have weeds growing, mow them before they develop flowers and go to seed and spread,” she adds.
Tips For Applying Weed Killers
If you choose to use a weed killer, follow these guidelines and tips.
Avoid Windy Days
Choose a day without wind to apply a weed killer. “Avoid applying herbicides on windy days to minimize drift onto other plants, pets, or people,” says Cannon.
Read the Label
Whether you use a chemical-based herbicide or a non-toxic option, read the label to know exactly how to apply it and protect yourself. “That label will list all the safety precautions along with PPE (personal protective equipment) that needs to be worn when working with the product,” says Cannon. These are strong chemical products that can have negative implications if not used correctly. “Not following the labeled instructions can cause long-term serious illnesses or even death to humans and animals along with long-lasting environmental damage,” says Cannon.
Avoid the Area
The label may state you need to wear protective gear when handling and applying the product. That is a good indicator that the product is harmful. After applying, avoid the area until it’s dry and there is less risk from exposure. “Keep pets and children away from treated areas until the product has fully dried or settled,” says Cannon.
