Introduction To Crabgrass Control

Welcome to our comprehensive guide on how to get rid of Crabgrass Naturally, one of the most common and stubborn weeds that can invade your beautiful lawn. We understand the frustration that comes with battling this persistent invader, but fear not! In this article, we will provide you with expert tips, strategies, and actionable steps to help you eradicate crabgrass and restore the health and lushness of your lawn.

What is Crabrabgrass?

Crabgrass, also known as finger grass or fonio, is an annual weed that thrives in warm seasons. Its peculiar name arises from the way it grows in clumps resembling crab legs, making it a noticeable eyesore against the backdrop of a lush, dark green lawn.

Interestingly, fonio has been cultivated in Africa for more than 5,000 years and is highly regarded as a nutritious staple crop. In 1849, the Patent Office introduced crabgrass into the United States with the intention of using it as a forage crop.

Belonging to the genus Digitaria, crabgrass earns its name from the Latin word “digitus,” meaning finger, owing to its finger-like appearance. While there exist at least 35 varieties of Digitaria, only two species prevail in the United States, namely hairy crabgrass (D. sanguinalis) and smooth crabgrass (D. ischaemum).

Both hairy and smooth crabgrass pose significant challenges to those striving for vibrant, green lawns. However, when it comes to eradicating crabgrass, distinguishing between the two species is unnecessary. The focus lies on eliminating these relentless intruders and restoring the beauty of your lawn.

The confusion between crabgrass and quackgrass is a common occurrence, as people often use these names interchangeably. However, it’s important to recognize that they are distinct grasses with different characteristics and eradication methods.

Quackgrass, also known as common couchgrass, is a cool-season perennial grass that spreads through deep rhizomes. It establishes a persistent presence in lawns and gardens, regenerating year after year. Its tenacious rhizomes make it a formidable opponent, requiring specific strategies for effective eradication.

On the other hand, crabgrass is a warm-season annual grass that germinates each year from seeds and completes its lifecycle within a single season. While crabgrass doesn’t possess the rhizome system of quackgrass, it compensates by producing copious amounts of seeds that ensure its survival and propagation.

Both grasses can wreak havoc on your lawn, but it is crucial to understand their distinct growth habits and choose the appropriate eradication methods accordingly. Tackling quackgrass requires addressing its deep-rooted rhizomes, while combating crabgrass involves preventing its seeds from germinating and establishing new growth.

By distinguishing between these two grasses and implementing targeted eradication techniques, you can effectively address the problems they cause in your lawn.

Understanding Crabgrass

Before we delve into the methods of eliminating crabgrass, it’s essential to have a clear understanding of this weed. Crabgrass (scientifically known as Digitaria) is an annual grassy weed that tends to thrive in warm-season grasses, such as Bermuda grass, Zoysia grass, and St. Augustine grass. It spreads rapidly, producing thousands of seeds that can lie dormant in the soil for years, waiting for the right conditions to germinate.

Understanding Crabgrass Groweth Cycle

To effectively eliminate crabgrass from your lawn, it is essential to understand its growth cycle. Digitaria species, including crabgrass, exhibit characteristics of warm-season annual grasses. They germinate during late spring and summer, thriving in warm weather, high temperatures, and even drought conditions.

The reproductive stage of the crabgrass lifecycle initiates as the days grow shorter, typically in late summer and fall. During this time, the growth of the plants slows down, and they begin to produce seed heads containing thousands of seeds. It is worth noting that mowing the crabgrass at this stage will not prevent it from setting seed, as it can still produce seeds even when it is just half an inch tall.

One of the challenges posed by crabgrass is its ability to withstand drought and tolerate high temperatures. This resilience allows it to flourish during the summer months when your lawn grass is already struggling. As it spreads out, it hampers the growth of your desired grass, and if left unchecked, it can swiftly take over your entire lawn.

To combat crabgrass effectively, intervention is necessary. Understanding its growth cycle allows you to devise appropriate strategies to prevent its proliferation and ultimately eradicate it from your lawn.

Using IWM Integrated Weed Management To Control Crabgrass

Integrated Weed Management (IWM) is an approach that combines multiple strategies and practices to manage and control crabgrass while minimizing reliance on herbicides effectively. It focuses on long-term weed control by integrating various methods in a holistic and sustainable manner. Here are some key components of IWM:

  1. Cultural Practices: IWM emphasizes cultural practices that promote healthy, dense turf or desirable plants, which in turn reduce weed growth and competition. These practices include proper watering, mowing at the correct height, overseeding, and maintaining adequate soil fertility.
  2. Mechanical Control: Mechanical control involves physically removing weeds through methods such as hand-pulling, hoeing, or using appropriate tools like weed trimmers or cultivators. It can be effective for managing small infestations or spot treatments.
  3. Mulching: The use of organic mulches, such as wood chips or straw, helps suppress weed growth by blocking sunlight and preventing weed seed germination. Mulching is commonly employed in landscape beds or garden areas to smother weed growth.
  4. Biological Control: Biological control involves introducing natural enemies of specific weed species, such as insects or pathogens, to reduce weed populations. This approach requires careful assessment and consideration to ensure the introduced species do not become invasive or pose risks to desirable plants.
  5. Chemical Control: While IWM aims to reduce reliance on herbicides, they can still play a role in weed management. Integrated Weed Management encourages the use of targeted, selective herbicides when necessary, and with proper application techniques and adherence to label instructions.

By implementing an Integrated Weed Management approach, you can effectively control weed populations, improve the health of your lawn or landscape, and minimize the impact on the environment.

Prventinting Crabgrass In Your Lawn, An Ounce of Prevention, Is Worth A Pound of Herbicide

Step 1: Timing Is Key

Timing plays a crucial role when it comes to effectively tackling crabgrass. Early spring is the ideal time to begin your efforts, as this is when crabgrass seeds start to germinate. By taking preemptive action during this period, you can prevent crabgrass from taking hold and outcompeting your desired turfgrass.

Step 2: Mowing, Watering, and Fertilizing Practices

The ultimate objective in the battle against crabgrass is to thwart the germination of its seeds within your lawn. One critical factor in achieving this is to avoid mowing your lawn too short. When you trim the grass too closely, you inadvertently create ideal conditions of light and warmth that promote the germination of warm-season grasses, including crabgrass.

On the contrary, maintaining taller grass provides shade and helps to keep the soil and overall lawn temperature cooler. This shade acts as a deterrent, preventing warm-season grasses from sprouting and taking hold. To accomplish this, it is recommended to adjust your mower blades to a height of approximately three inches during periods of peak growth. By keeping the grass at this taller length, you maximize the shading effect and discourage the germination and growth of unwanted grasses such as crabgrass.

Adhering to this practice during the appropriate growing conditions allows you to maintain a healthy, resilient lawn that is less susceptible to the encroachment of warm-season grasses. Remember, the goal is to keep your grass as tall as possible to impede the germination and establishment of crabgrass and other undesired grass species.

Regular Mowing

Frequent mowing helps keep crabgrass at bay by preventing it from producing seed heads. Set your mower to a suitable height that removes only the top one-third of the grass blades, as this encourages the grass to grow thicker and compete more effectively against crabgrass.

Correct Watering Technique

Crabgrass thrives in lawns with weak, shallow root systems, often caused by overwatering. Water your lawn deeply and infrequently to promote deeper root growth in your desired grass and discourage crabgrass from taking root.

Avoid Fertilizing in the Summer

It is important to refrain from fertilizing cool-season lawns during the summer months. While the intention behind summer fertilization may be to achieve a greener lawn, it actually works in favor of crabgrass rather than benefiting the cool-season turf.

During the summer, lawns naturally enter a period of dormancy due to the high temperatures, and this dormancy is not caused by a lack of nutrients. Fertilizing during this time can lead to an imbalance in the lawn’s nutrient levels and provide an advantage to crabgrass.

Crabgrass, being a warm-season grass, thrives in the summer when the conditions are most favorable for its growth. By fertilizing the lawn during this period, you inadvertently provide additional nutrients that fuel the growth of crabgrass, enabling it to outcompete the cool-season turf.

To maintain a healthy lawn and discourage crabgrass growth, it is best to avoid fertilizing during the summer months. Instead, focus on providing proper care and maintenance to your cool-season turf during its active growth periods in spring and fall.

Autumn Lawn Prep

Engaging in autumn lawn care practices can prove instrumental in controlling the growth of crabgrass by disrupting its life cycle. By implementing the following steps, you can effectively combat the presence of crabgrass and promote the healthy development of your turfgrass:

  1. Add compost in the fall: Applying compost during autumn nourishes your turfgrass, facilitating its growth and simultaneously inhibiting weed growth. This helps create a more robust lawn that is less susceptible to crabgrass invasion.
  2. Address bare spots: Crabgrass often creates bare spots by outcompeting your turfgrass and then perishing in the fall. By addressing these bare spots and promoting healthy turfgrass growth through overseeding or reseeding, you can prevent crabgrass from seizing the opportunity to establish itself.
  3. Seed cool-season lawns: Autumn is an optimal time for seeding cool-season lawns as it hampers the growth of crabgrass. Any crabgrass seeds that manage to sprout will be eradicated by the first frosts, preventing their further development.
  4. Aerate the lawn: Compacted soil can impede the growth of turfgrass while favoring the growth of crabgrass. By aerating the lawn in the fall, you alleviate compaction, improve soil structure, and provide an environment conducive to the flourishing of your desired grass species.
  5. Regularly rake leaves: Raking leaves on a consistent basis ensures that your grass receives ample sunlight. This helps maintain the health and vigor of your turfgrass, making it less susceptible to crabgrass encroachment.

By incorporating these autumn lawn care practices into your routine, you create an environment that discourages the growth of crabgrass while promoting the overall vitality of your lawn.

Step 3: Mechanical Removal of Crabgrass

When dealing with isolated crabgrass patches, mechanical removal can be an effective approach. Follow these steps for safe and efficient removal:

  1. Equip yourself with a hand weeder or a similar tool designed for weed removal.
  2. Identify the crabgrass plants by their clumpy growth habit and light green color.
  3. Insert the tool into the soil near the base of the crabgrass, ensuring you get as much of the root system as possible.
  4. Gently pry the weed upward, loosening the soil around it to minimize root breakage.
  5. Dispose of the weed immediately to prevent any remaining seeds from spreading.

A crucial aspect of controlling crabgrass is to be vigilant and identify immature seed heads. These seed heads contain a multitude of seeds, and removing them promptly is vital in preventing further proliferation. However, once the crabgrass seed heads have fully matured, it is advisable to leave them undisturbed to avoid scattering the seeds.

When dealing with immature seed heads, it is best to remove them as soon as you spot them. By doing so, you prevent the seeds from dispersing and minimize the chances of new crabgrass plants sprouting. However, it is important to exercise caution when handling mature crabgrass plants that have already gone to seed. Pulling them at this stage can disturb the soil and inadvertently scatter the seeds, creating favorable conditions for the growth of new crabgrass plants.

By paying attention to the maturity of the seed heads and taking appropriate action, you can effectively curtail the spread of crabgrass and prevent its reemergence.

Step 4: Herbicides for Crabgrass Control

Herbicides can be a valuable tool in your fight against crabgrass, but it’s essential to choose the right herbicide and apply it correctly. Here are two main types of herbicides commonly used for crabgrass control:

When it comes to eliminating established crabgrass plants, it is necessary to adjust your approach. Pre-emergent herbicides, commonly referred to as crabgrass preventers, are effective in targeting germinating seeds before they establish themselves. However, once crabgrass has taken root, a different strategy is required.

There are multiple approaches you can employ to kill established crabgrass plants, and utilizing a combination of methods will increase your chances of success. Selective herbicides specifically designed to target crabgrass, known as crabgrass killers, can be used effectively. Additionally, there are several organic and natural methods available for killing crabgrass plants.

By utilizing a combination of these approaches, you can combat crabgrass and prevent it from overtaking your lawn and producing more seeds.

Proper Identification of Crabgrass

Before embarking on your mission to eradicate crabgrass, it is crucial to understand the timing involved. Familiarize yourself with the life cycle of crabgrass to determine the most opportune moment to take action. Additionally, it is essential to verify that the weed you are targeting is indeed crabgrass, as misidentification can lead to ineffective treatments.

Achieving success in eliminating crabgrass hinges on being well-informed about your options, meticulously planning your approach, and gathering the necessary tools and materials. Once you have prepared adequately, it is a matter of executing your plan with diligence. Consistency and staying proactive in your efforts make the process of killing crabgrass more manageable.

If you stay mindful of the timing, are certain of your target, and remain committed to your plan, you can effectively combat and eradicate crabgrass from your lawn.

Timing is Everything

The appropriate timing to kill crabgrass depends on its specific life cycle stage, and you have various methods at your disposal for each phase:

  1. Germination: During the germination stage, you can effectively combat crabgrass by utilizing pre-emergent herbicides. These herbicides prevent the seeds from sprouting and inhibit root development. Commonly known as crabgrass preventers, pre-emergents are available in liquid or granular form. It is crucial to apply them early in the spring to ensure their effectiveness.
  2. Seedling: Pre-emergent herbicides continue to be effective for two to six months, which covers the critical period when seedlings attempt to establish themselves. However, it is essential to note that not all pre-emergents are the same. Be sure to carefully read and follow the instructions provided on the packaging for detailed information about the duration of their effectiveness.
  3. Growth: Once crabgrass has successfully established its roots and enters the growth stage, selective post-emergent herbicides are the most effective option. These herbicides specifically target crabgrass while sparing your desired lawn grasses. When applied correctly, they can help eradicate established crabgrass plants.
  4. During the reproduction stage of crabgrass, it is important to identify and remove immature seed heads promptly. By doing so, you prevent the seeds from dispersing and reduce the chances of future growth. In the fall, you can mow your lawn short to encourage the germination of any mature seeds that may be present. Once the freezing temperatures of winter arrive, these germinated seeds will perish.
  5. During the dormancy stage, crabgrass seeds lie dormant throughout the winter. It is necessary to wait until spring to resume your efforts in controlling and eliminating crabgrass.By being proactive in removing immature seed heads and taking advantage of the natural freeze-thaw cycle, you can disrupt the reproduction and growth of crabgrass, reducing its presence in your lawn.

Pre-emergent Herbicides

Pre-emergent herbicides work by creating a barrier in the soil that prevents crabgrass seeds from germinating. It’s crucial to apply pre-emergent herbicides at the right time, typically when soil temperatures reach around 55 to 60 degrees Fahrenheit (12 to 15 degrees Celsius).


Prodiamine, a member of the Dinitroaniline family, is a widely used pre-emergent herbicide. It is commonly known by its trade name, Barricade. Other pre-emergent herbicides similar to Prodiamine include Trifluralin, Pendimethalin, and Benefin. Prodiamine is a popular choice for crabgrass control due to its low volatility and its ability to break down into non-phytotoxic levels within a relatively short time.

Pure Prodiamine is available in a fine granular form and can be applied by mixing it with water, creating an orange/yellow solution, or by combining it with a granular fertilizer and dispersing it using a spreader. It is important to note that Prodiamine does not possess any post-emergent properties, meaning it is not effective against already established crabgrass plants.

Using Prodiamine as a pre-emergent herbicide helps prevent the germination and establishment of crabgrass by creating a barrier in the soil. This barrier inhibits the growth of crabgrass seedlings, reducing their presence in your lawn.

When using any herbicide, including Prodiamine, it is crucial to follow the instructions provided by the manufacturer for proper application and safety precautions.

If you have any further questions or require additional guidance, please feel free to let me know.


Pendimethalin is a herbicide belonging to the dinitroaniline class. It is utilized for both preemergence and postemergence applications to control annual grasses as well as certain broadleaf weeds effectively. This professional-grade pre-emergent herbicide acts as a meristematic inhibitor, suppressing the growth of grasses and broad-leaf weeds in both cool-season and warm-season grasses found in commercial and residential lawns.

When used as a pre-emergent herbicide, pendimethalin is applied before the targeted weeds emerge from the soil. By creating a barrier, it prevents the germination and establishment of annual grasses and broadleaf weeds in lawns.

Pendimethalin serves as an important tool in the management and maintenance of healthy lawns, providing effective control against troublesome weed species. However, it is essential to carefully follow the instructions provided by the manufacturer when using pendimethalin to ensure proper application rates, timing, and safety precautions.

Post-emergent Herbicides

Post-emergent herbicides are used when crabgrass has already germinated and is actively growing. They target and kill the existing crabgrass plants in your lawn. Ensure you select a post-emergent herbicide specifically formulated for crabgrass and follow the application instructions carefully.

Fenoxaprop p-ethyl

Fenoxaprop p-ethyl, commonly known as Acclaim Extra Selective Herbicide, is a professional-grade post-emergent herbicide specifically designed for controlling annual and perennial grasses.
