<Back to All Blogs

A lush, green lawn is often seen as a symbol of a well-maintained home and yard, but achieving and maintaining that perfect lawn requires effort and the right care. One of the most common challenges homeowners face is dealing with weeds, which can quickly take over your yard, crowding out your grass and creating an eyesore. At Green Army, we believe that a beautiful lawn goes beyond just mowing — it takes a comprehensive approach to lawn care, including effective weed control.

As a leading company in home and yard maintenance, Green Army is committed to improving the health of your home and neighborhood. We use the best people, products, technology, and systems to ensure your lawn receives the best care possible. Our lawn weed control service is designed to eliminate invasive weeds and promote healthy grass growth, all while aligning with our eco-friendly mission. In this article, we’ll guide you through key aspects of weed control, including timing, techniques, and when to combine it with other services like fertilization and pest control to ensure your lawn stays in top condition.

Whether you’re preparing for a new season or maintaining your current lawn, knowing the right strategies for weed control can make all the difference. Let’s dive into the essential aspects of this important lawn care service.

What Month is Best for Weed Control?

Timing is crucial when it comes to weed control. Applying the right treatment at the appropriate time of year can significantly impact its effectiveness. For optimal results, the best months for weed control typically fall during the spring and fall seasons.

Spring: The Ideal Time for Pre-Emergent Weed Control

In early spring, the soil begins to warm up, making it the perfect time to apply pre-emergent weed control. This type of treatment works by preventing weed seeds from germinating, particularly in the cooler months when weeds like crabgrass and dandelions start to sprout. Applying pre-emergent in late winter or early spring (typically around late March to early April) can help keep your lawn free of those pesky weeds before they even have a chance to take root.

Fall: A Time for Post-Emergent Weed Control

As the weather cools and your lawn begins its seasonal transition, fall becomes an ideal time for post-emergent weed control. This type of treatment targets weeds that have already appeared and are actively growing. Weeds like dandelions and clover may still be present in the fall, making it the perfect time to tackle them before they go dormant for the winter. Fall is also a great time to apply fertilization as your grass is still actively growing and can benefit from the nutrients.

By applying weed control during these key months, you set the stage for a healthy, thriving lawn that can stand up to weeds and other pests.

In addition to weed control, Green Army offers a full suite of services to support your lawn’s health, including fertilization, gutter cleaning, and power washing. By combining these services, you can ensure your lawn receives the care it needs year-round, while maintaining a clean and healthy environment for your home.

Proper timing for weed control is just one piece of the puzzle—working with a knowledgeable team like Green Army ensures that your lawn stays in top shape throughout the year.

What Month Should I Put Weed Killer on My Lawn?

Knowing when to apply weed killer is essential for achieving the best results. The timing of weed killer application depends on the type of weeds you’re targeting and the overall health of your lawn. In general, the best months to apply weed killer are in early spring and late spring, but the specific timing can vary.

Early Spring: Pre-Emergent Weed Control

As the weather warms up, it’s important to address weeds before they have a chance to germinate. Applying pre-emergent weed killer in early spring (usually around March or April) is an effective method for preventing the growth of common weeds like crabgrass, chickweed, and dandelions. Pre-emergent weed killers work by creating a barrier in the soil that stops weed seeds from sprouting. This type of treatment is especially beneficial for annual weeds that germinate early in the spring.

Timing is critical for pre-emergent treatments, as applying them too late in the season can allow weeds to take root. By applying weed killer early, you can prevent these weeds from becoming established and keep your lawn looking healthy and pristine throughout the year.

Late Spring: Post-Emergent Weed Control

If you missed applying pre-emergent or if new weeds have already begun to grow, late spring (around May to June) is the ideal time for post-emergent weed killers. Unlike pre-emergents, post-emergents target weeds that have already emerged and are actively growing. These weed killers are effective for tackling broadleaf weeds, such as dandelions, clover, and plantains, that have already established themselves in your lawn.

When applying post-emergent weed killer, make sure to follow all product instructions to avoid harming your grass. It’s also a good idea to water your lawn first to help the weed killer penetrate the soil more effectively.

By applying weed killer at the right time in early spring and late spring, you can effectively control weeds and maintain a healthy lawn. At Green Army, we recommend combining these treatments with other services like fertilization, lawn care maintenance, and pest control to ensure your lawn remains vibrant and free from unwanted weeds all season long.

Additionally, our team can help you with other essential tasks like gutter cleaning or outdoor furniture cleaning, ensuring every aspect of your yard and home receives the attention it deserves.

Should You Fertilize or Weed Control First?

When it comes to maintaining a healthy lawn, the question of whether to fertilize or apply weed control first is a common one. Both of these essential treatments play crucial roles in lawn care, but timing and the order of application can make a difference.

Weed Control First

In most cases, it’s best to apply weed control before fertilizing your lawn. Here’s why:

  • Weed Control Efficiency: If you fertilize first, the added nutrients can encourage the growth of weeds along with your grass. Applying weed killer first ensures that weeds are dealt with before they have a chance to compete for nutrients.
  • Targeting Weeds Early: By using weed control products before fertilization, you can more effectively target and eliminate weeds, preventing them from thriving during the growing season.

In early spring, applying pre-emergent weed control is especially important because it prevents weed seeds from germinating in the first place. Afterward, you can apply fertilization to give your grass the nutrients it needs to grow strong and healthy.

Fertilization After Weed Control

Once the weed control treatment has had time to work, fertilizing your lawn is the next step. Fertilization provides essential nutrients, such as nitrogen, phosphorus, and potassium, which help your lawn grow thicker and more resilient to pests and diseases. By waiting to fertilize after weed control, you allow your lawn to focus on recovering from the weed treatment and ensure the fertilization process is more effective.

Combining Weed Control and Fertilization

In some cases, you can find products that combine both weed control and fertilization, which can save time and effort. These combined treatments are typically applied in late spring or early summer when weeds are actively growing and grass is in need of nutrients. However, it’s essential to follow the recommended application instructions and ensure that the product is suitable for your specific lawn type.

At Green Army, we provide comprehensive lawn care maintenance services, including both weed control and fertilization, to ensure your lawn gets the right care at the right time. Our professionals will help you determine the best approach based on your lawn’s unique needs.

In addition to weed control and fertilization, we offer a variety of services like gutter cleaning, power washing, and mosquito control to keep your home and yard in pristine condition year-round. Let Green Army help you create a healthy, thriving lawn with the best care possible.

Should You Mow Before Weed Control?

Mowing your lawn regularly is an essential part of maintaining a healthy yard, but when it comes to applying weed control, the timing of your mowing is just as important. Mowing before applying weed control can influence the effectiveness of the treatment, and it’s essential to know the right approach.

Mow Before Applying Weed Control

For the best results, it’s generally recommended to mow your lawn before applying weed control. Here’s why:

  • Improved Weed Control Application: When you mow, you help expose more of the weed surfaces, making it easier for the weed killer to make contact with the plant. This can improve the absorption of the treatment and make it more effective at killing weeds.
  • Grass Health: Mowing your lawn keeps the grass at an optimal height, allowing it to absorb the right amount of sunlight and nutrients. This helps it stay healthy and resilient, while also making it easier for the weed killer to target the weeds without harming the grass.
  • Avoid Applying Weed Control on Overgrown Lawns: If your grass is too long, it can shade the weeds, preventing the weed control from reaching them directly. Mowing helps prevent this, ensuring that weeds are effectively treated.

When to Mow After Applying Weed Control

It’s important to wait after applying weed control before mowing your lawn again. This waiting period allows the weed killer to be fully absorbed into the weeds, maximizing its effectiveness. Typically, you should wait 24 to 48 hours after applying weed control before mowing.

  • Avoid Mowing Immediately: Mowing too soon can cut off the weeds before the weed control has had time to work, potentially reducing its effectiveness.
  • Mowing Too Soon: If you mow too soon after applying weed control, you risk spreading the chemicals to areas you want to avoid or damaging the effectiveness of the treatment.

Combining Mowing with Other Lawn Services

In addition to regular mowing and weed control, other services like fertilization, lawn care maintenance, and pest control can greatly improve your lawn’s health. For example, after mowing and applying weed control, you can schedule fertilization to give your lawn the nutrients it needs to grow strong and resist future weed growth.

At Green Army, we offer a range of services, including power washing, gutter cleaning, and mosquito control to keep both your lawn and your home in excellent condition. Our expert team is here to provide personalized advice and services to ensure your lawn stays healthy, vibrant, and free of weeds.

By combining proper mowing techniques with effective weed control, you can enjoy a cleaner, greener lawn that enhances the beauty of your home. Let Green Army take care of all your lawn care needs, so you can enjoy a worry-free yard all year long.

Can You Apply Weed Control and Fertilizer at the Same Time?

Many homeowners wonder if they can apply weed control and fertilizer simultaneously to save time and effort. While the idea of combining these two treatments may seem convenient, there are a few important factors to consider before applying them together.

Weed Control and Fertilizer: Separate Functions

Both weed control and fertilizer serve different purposes:

  • Weed Control: The primary goal of weed control is to eliminate or prevent the growth of weeds on your lawn. Weed control products, such as herbicides, target weeds directly, either by preventing seed germination (pre-emergent) or by killing existing weeds (post-emergent).
  • Fertilization: On the other hand, fertilizers provide essential nutrients to your grass, helping it grow stronger and more resilient. Fertilization supports healthy root development, improves color, and helps the grass outcompete weeds for resources.

While these two treatments can be applied at different times, it’s important to understand how they interact.

Can You Apply Weed Control and Fertilizer Together?

Yes, it’s possible to apply weed control and fertilizer at the same time, but only under certain conditions.

  • Combination Products: Some products on the market combine both weed control and fertilization in a single treatment, which can be convenient for homeowners looking to address both issues at once. These combination products are typically used in late spring or early summer when weeds are actively growing and grass needs nutrients to thrive. However, it’s important to read the labels carefully and follow the instructions to ensure safe and effective application.
  • Separate Treatments: If you’re using separate weed control and fertilizer products, it’s generally best to apply them at different times. Here’s a recommended approach:
    • First: Apply weed control (either pre-emergent or post-emergent) to address weeds.
    • Then: Wait a few days before applying fertilizer, allowing the weed control to work effectively.

By waiting a few days between the applications, you give the weed control time to absorb and work on the weeds, ensuring maximum effectiveness. Applying both treatments too quickly can reduce the effectiveness of either one and may result in uneven lawn care results.

When to Apply Weed Control and Fertilizer

  • Early Spring: Apply pre-emergent weed control first, followed by fertilization in late spring for a healthy lawn.
  • Late Spring: For existing weeds, apply post-emergent weed control, followed by fertilization shortly thereafter.

At Green Army, we offer professional lawn care maintenance services, including weed control and fertilization, to ensure your lawn receives the best treatment at the right time. Our experts can also assist with other tasks, such as gutter cleaning, power washing, and even mosquito control, so your entire yard stays well-maintained.

While it is possible to apply weed control and fertilizer at the same time, doing so effectively requires careful consideration of the type of products you’re using and their timing. Whether applying them separately or using combination treatments, it’s essential to follow recommended guidelines for the best results. If you’re unsure about the timing or application process, consider reaching out to Green Army for expert advice and professional services. We’ll help you create a lawn that’s healthy, vibrant, and free of weeds, while also offering services like lawn fertilization, mosquito control, and pest maintenance for an all-encompassing approach to yard care.

When Not to Fertilize a Lawn?

Fertilizing your lawn is crucial for promoting healthy growth and a lush, green appearance. However, there are specific times when you should avoid fertilizing to ensure the health of your lawn and prevent potential damage. Knowing when not to fertilize is just as important as knowing when to fertilize.

1. During Extreme Heat or Drought Conditions

Fertilizing your lawn during periods of extreme heat or drought can stress the grass and lead to poor results. High temperatures and dry conditions can prevent the grass from effectively absorbing the nutrients in the fertilizer.

  • Why Not Fertilize? Applying fertilizer during these conditions can cause the grass to burn or become stressed, as the fertilizer encourages rapid growth that the grass cannot support due to water or nutrient deficiencies.
  • Solution: Wait until temperatures cool down and the lawn has access to sufficient water before fertilizing.

2. When Your Lawn is Dormant

Lawn growth slows or stops entirely during the winter months, especially in cooler climates. Fertilizing a dormant lawn can waste your resources, as the grass won’t actively absorb the nutrients during this time.

  • Why Not Fertilize? When the grass is dormant, it is not growing actively, and fertilizer applications won’t be absorbed effectively.
  • Solution: Apply fertilizer during the growing season, typically in early spring or late fall, when the lawn is actively growing.

3. After Recent Herbicide Application

If you’ve recently applied a weed control treatment, it’s important to wait before fertilizing. Fertilizing too soon after applying herbicides can interfere with the effectiveness of both treatments.

  • Why Not Fertilize? Fertilizer can sometimes interfere with the weed killer’s effectiveness, and in some cases, the combination can stress your lawn.
  • Solution: Wait at least 2 weeks after applying weed control before applying any fertilizer to allow the herbicide to work effectively.

4. If Your Lawn Is Already Over-Fertilized

Over-fertilizing your lawn can lead to nutrient burn, where the grass becomes damaged and turns yellow or brown due to an excess of nutrients.

  • Why Not Fertilize? Fertilizing again too soon can cause toxic buildup in the soil, leading to poor grass health.
  • Solution: If you’ve already fertilized recently, wait before applying any more fertilizer. If you’re unsure, consider testing your soil to determine if additional fertilization is necessary.

5. During Wet Weather or Heavy Rain

Fertilizing during or right before heavy rain can cause the nutrients in the fertilizer to wash away before they are absorbed by the soil. This can lead to ineffective fertilization and potential pollution of nearby water sources.

  • Why Not Fertilize? The excess water can cause the fertilizer to runoff, preventing it from reaching the roots and potentially harming the environment.
  • Solution: Wait for a dry day with mild conditions before applying fertilizer to ensure proper absorption.

6. When Your Lawn Is Weakened

If your lawn is already weak due to pest infestations, disease, or other environmental stressors, it’s best to hold off on fertilizing.

  • Why Not Fertilize? Fertilizing a stressed lawn can exacerbate the problem, encouraging rapid growth that the lawn cannot support.
  • Solution: Address the underlying issue, such as pest control or mosquito treatment, before applying fertilizer. Once the lawn is healthier, you can fertilize it to help with recovery.

Knowing when not to fertilize your lawn is just as important as knowing when to apply fertilizer. Avoid fertilizing during extreme heat, drought, winter dormancy, or immediately after herbicide application.
