should you mow before weed and feed

Sticking to a lawn care schedule is crucial for maintaining a gorgeous and healthy-looking grass throughout the season. One common question that arises is whether to mow before or after applying weed and feed. The timing of mowing in relation to weed and feed application can impact the effectiveness of these lawn treatments. In this article, we will explore the different lawn care methods, discuss whether to apply weed and feed before or after mowing, and provide tips for optimal lawn care.

Understanding Different Lawn Care Methods

Before we delve into the topic of mowing and weed and feed, it’s important to familiarize yourself with the various lawn care methods. This knowledge will help you develop an optimal strategy for maintaining a healthy and weed-free lawn.

One popular method is weed and feed, which combines fertilizer and herbicide. This powerful combination nourishes your grass while targeting and eliminating weeds. Herbicide sprays are another effective option for weed control. They selectively target specific types of weeds, allowing you to tackle problem areas with precision. If preventing weed growth is your priority, pre-emergent weed killers are the way to go. These products stop weed seeds from germinating, giving your lawn a head start.

Of course, proper nutrition is essential for a thriving lawn. You have a choice between lawn fertilizer in granule or liquid form. Granules are easy to apply and release nutrients slowly over time, providing a steady supply of nourishment. Liquid fertilizers, on the other hand, can offer faster results as they are quickly absorbed by the soil.

Understanding these lawn care methods is crucial as they lay the foundation for effective mowing and weed and feed practices. By tailoring your approach based on your needs and the specific characteristics of your lawn, you can achieve a lush, vibrant, and weed-free outdoor space.

Mowing Before or After Weed and Feed?

The question of whether to mow before or after applying weed and feed depends on various factors. However, it is generally recommended to mow before applying weed and feed for better effectiveness. Weeds have a larger foliage surface area before mowing, making it easier for the herbicide to adhere to them. After mowing, it is ideal to apply weed and feed two days later, allowing the herbicide to penetrate the grass and start working.

The specific timing may vary depending on the product used and the grass type. For cool-season grasses found in regions with significant temperature changes, such as fescue or ryegrass, weed and feed should be applied in spring and fall. These formulations are designed to cater to the specific needs of cool-season grasses. On the other hand, southern grasses like Bermuda or St. Augustine thrive in warmer climates and require an early spring application of weed and feed to effectively control weeds and promote grass health.

To summarize, mowing before applying weed and feed allows for better adherence of the herbicide to weeds. The specific timing for applying weed and feed may vary based on the grass type and regional climate. Choose the appropriate cool-season formulations for cool-season grasses and southern formulations for southern grasses. By following these optimal mowing times and selecting the right formulations, you can ensure a healthier and more vibrant lawn.

Mowing Before or After Weed Killer?

When it comes to controlling weeds in your lawn, there are two types of weed killers that you can use: pre-emergent and post-emergent herbicides.

Pre-emergent herbicides are applied in late autumn or winter to prevent weed seeds from germinating. To ensure the effectiveness of pre-emergent weed control, it is recommended to mow the grass one final time before applying the pre-emergent granules. By doing so, you remove any existing weeds and create an optimal surface for the herbicide to penetrate.

Post-emergent herbicides, on the other hand, target actively growing weeds. To maximize their effectiveness, it is best to mow at least two days before or after applying the post-emergent treatment. This timing allows the herbicide to reach the weed’s foliage and effectively eliminate it, ensuring better weed control in your lawn.

By following the proper mowing timing in relation to weed killer application, you can achieve better results in weed control and maintain a healthy and lush lawn.

Should I Mow my Lawn before or after Applying Weed and Feed?

When deciding whether to mow your lawn before or after applying weed and feed, consider the best approach for your grass. Mowing before can help the nutrients penetrate the soil, while mowing after can remove any dead weeds. Both are essential lawn care tips to ensure a healthy and vibrant yard.


To achieve a healthy and vibrant lawn, it is essential to follow optimal lawn care practices, particularly when it comes to mowing and weed treatment. By mowing your lawn before applying weed and feed, you can enhance the effectiveness of the treatment. This is because mowing prior to weed and feed application allows the herbicide to target a larger surface area of the weeds, leading to better control.

Furthermore, having a good understanding of the different lawn care methods, such as pre-emergent and post-emergent weed control, is crucial in determining the timing of your mowing routine. Pre-emergent herbicides are typically applied in late autumn or winter, before weed seeds germinate, and it is advisable to mow one final time before applying these granules. As for post-emergent herbicides, which target actively growing weeds, mowing at least two days before or after the treatment is recommended.

By adhering to these tips and establishing a consistent lawn care schedule, you will be on your way to achieving a healthy and envy-inducing lawn. Remember, optimal lawn care practices involve mowing before applying weed and feed, understanding the different weed control methods, and following a consistent lawn care routine. With these steps in place, your lawn will thrive and become the centerpiece of your outdoor space.
