Broadleaf weeds have wide, distinct leaves with a different vein pattern from grassy weeds. Some will also have colorful flowers that sprout and stand out among the grass where it is growing.

There are hundreds of types of broadleaf weeds, but some common ones include dandelion, clover, dollarweed, and plantain.

Knowing what type of broadleaf weed you have is crucial for choosing the right control strategy. A herbicide that might work for one type of weed may not be effective against a different weed.

To identify a broadleaf weed, look for its unique characteristics, such as its leaf shape and vein pattern. You can also use smartphone applications that can identify weeds from a photograph, especially for broadleaf weeds.

Proper identification of the weeds is essential before selecting the most economical and effective herbicide. Suggested resources for weed identification include the New Jersey Weed Gallery, the Virginia Tech University Weed Identification Website, and the book, Weeds of the Northeast, Second Edition.

Here are some common types of broadleaf weeds you may encounter on a lawn:

To prevent broadleaf weeds from growing in your lawn, you can implement cultural practices that promote a thick and healthy lawn. This will make it difficult for the weeds to establish themselves.

Regular mowing is essential to keep your grass at the right height and prevent weeds from growing. Water your lawn deeply yet infrequently to encourage deep root growth, which will also help to prevent weeds.

Here are some recommended fertilizers and herbicides to help you achieve a weed-free lawn:

To prevent broadleaf weed growth, implementing cultural practices that promote a thick, healthy lawn is key. This will make it difficult for weeds to establish themselves.

Mowing your grass regularly is a must. Watering deeply yet infrequently is also essential, as this will encourage deep root growth and make your lawn more resilient to weeds.

Understanding which nutrients your turf variety needs at the right time of the year is crucial. This will help prevent broadleaf weeds and maintain the overall health of your lawn.

Regular fertilization is also necessary. Here are some fertilizers that can help promote a healthy lawn:

By following these tips, you can create a lawn that's resistant to broadleaf weeds and looks its best all season long.

Getting into the weeds, literally, is a crucial step in preventing their growth. You've got to know what you're up against.

2,4-D is a widely used herbicide that provides broad-spectrum weed control in turfgrass, making it a great starting point for many weed control plans.

The key to successful weed control is often found in the combination of active ingredients. Mixing 2,4-D with other herbicides like MCPA, MCPP, and dicamba can provide better weed control than using a single active ingredient alone.

Dicamba, for example, is particularly effective against summer annual weeds with a prostrate growth habit, such as knotweed and purslane.

Isoxaben is another herbicide that can be used for preemergence control of winter annuals and some perennial broadleaf weeds, making it a great addition to your weed control arsenal.

Carfentrazone and sulfentrazone are quick-acting herbicides that cause rapid desiccation of broadleaf weed species, making them a valuable tool for targeted weed control.

To effectively treat broadleaf weeds in your lawn, start by inspecting your yard to identify the specific weed type. Use a broadleaf weed killer that's recommended for your specific weed type, and always read and follow the label directions.

Wear proper personal protective equipment before applying any herbicides to your yard, as this will help prevent exposure to harsh chemicals. Mix MSM Turf Herbicide with water and add a surfactant like Nanotek Surfactant to enhance its effectiveness.

Spray the mixture where the broadleaf weeds are established, being careful not to drift onto desirable plants. Avoid spraying areas where ornamental plants would be contacted, and only spray on the surface of the weeds, allowing the herbicide to absorb into the plant.

Timing is crucial when applying herbicides; for post-emergent herbicides like MSM Turf Herbicide, apply when the plant is young and actively growing. Check back in 10 to 14 days to see how well the initial application has worked, and reapply as necessary.

Worth a look: Is It a Weed or a Plant

For harder-to-kill weeds like Oxalis and Onehunga Weed, consider using Hydrocotyle Killer. Always spray on a still day to avoid spray drifting onto desirable plants, and read the label carefully before applying any herbicides.

Growing healthy, dense grass is the first step in controlling weeds in your lawn; proper watering, mowing, and fertilizing can discourage weeds from growing. Hand-weeding small weed populations can be effective, but chemical weed killers shouldn't be relied on as a substitute for proper lawn management.

Products containing 2,4-D or triclopyr can effectively control creeping Charlie, but at least two applications are necessary for good control. If you're dealing with a small infestation of violets, digging them up can be an option, but broadleaf herbicides containing triclopyr are usually the most practical solution for larger areas.

To apply herbicides effectively, it's essential to treat individual plants or weed-infested spots, not the entire lawn. General broadcast application is not recommended.

A fresh viewpoint: Food Not Lawns

Use herbicides when temperatures are between 65 and 85 degrees Fahrenheit, and avoid applying them when temperatures are expected to rise above 85 degrees Fahrenheit within 24 hours. This will help prevent herbicide drift and ensure the best results.

Keep in mind that once a sprayer is used for herbicides, it should only be used for that purpose, not for applying liquid fertilizers, insecticides, or fungicides. This will help prevent contamination and ensure accurate application.

Organic herbicides are non-selective, meaning they'll kill any plant leaves they contact, and are not systemic, so they won't move to growing points.

There are currently no selective organic herbicide options that kill only broadleaf weeds without harming lawn grasses. These products may control weed seedlings, but most weeds will recover a week or two after application.

Chelated iron products are an alternative to traditional synthetic products and are selective, effective against many broadleaf weeds and safe to the grass. However, they are not organic (OMRI approved) and need multiple applications 2 to 4 weeks apart for effective weed control.

Corn gluten meal products are not effective for broadleaf weed control.

Applying broadleaf herbicides properly requires some finesse. Before applying any herbicide, carefully read and follow the label directions.

You should avoid spray drift problems when applying liquid formulations. Don't spray when winds exceed five miles per hour.

To prevent spray drift, select nozzles that produce coarse droplets and apply the liquid using a low sprayer pressure. This will help minimize the risk of herbicide drifting onto other plants.

Keep the nozzle close to the ground when spraying to ensure accurate application. Don't spray the entire lawn if only a few areas have broadleaf weed problems - spot treat these areas instead.

Apply just enough material to wet the leaf surfaces, as overapplication can be wasteful and potentially harm other plants.

Wear protective gear like long-sleeved shirts, long pants, shoes, goggles, and chemical-resistant gloves when mixing and applying broadleaf lawn weed killers.

Wash non-disposable gloves with soap and water before removing them, and thoroughly wash hands, face, and other exposed skin with soap and water after application.

A shower minimizes health risks from pesticides, so take one as soon as possible after application.

Change clothing and launder clothes separately from other clothes before reuse to prevent any potential contamination.

Don't re-enter or permit others, including children and pets, to enter the treated area until the material has thoroughly dried.

Apply herbicides when temperatures are between 65 and 85 degrees Fahrenheit to minimize health risks and ensure effective killing of broadleaf weeds.

Avoid applying herbicides when temperatures are expected to rise above 85 degrees Fahrenheit within 24 hours of application, or when rain is expected within 24 hours of application.

September and October are ideal months to tackle lawn care with a combination of herbicides and practices that improve canopy density for long-lasting weed control.

Temperatures during this period are perfect for fertilizing with nitrogen or seeding to enhance lawn density. This is especially crucial if you've struggled with winter or summer annual weeds in the past.

To minimize the danger of herbicide drift, it's essential to apply herbicides during a calm part of the day when there's little or no wind.

Wear a long-sleeved shirt, long pants, shoes, goggles, and chemical-resistant gloves when mixing and applying broadleaf lawn weed killers.

It's essential to protect yourself from potential harm, as pesticides can be hazardous to your health.

Wash non-disposable gloves with soap and water before removing them to prevent any remaining chemicals from coming into contact with your skin.

After application, thoroughly wash hands, face, and other exposed skin with soap and water to minimize health risks from pesticides.

A shower can help minimize health risks from pesticides, especially if you've been handling them extensively.

Change clothing and launder clothes separately from other clothes before reuse to prevent any potential chemical residue from being transferred to other items.

Don't re-enter or permit others, including children and pets, to enter the treated area until the material has thoroughly dried.

Spring is a great time to get outside and enjoy the warmer weather. As we discussed earlier, the average temperature in Spring is around 50°F (10°C), making it perfect for outdoor activities.

In the Spring, the risk of thunderstorms increases, with an average of 20 days with thunderstorms per year. This is especially true in areas prone to tornadoes, where the risk is significantly higher.

The warmer weather in Spring also means that the risk of heat-related illnesses, such as heat exhaustion, increases. In fact, the National Weather Service reports that heat-related illnesses are more common in the Spring and Summer months.

As we mentioned earlier, the Spring is a great time to plant flowers and vegetables, but it's also essential to be mindful of the pollen count. With an average of 1,000 grains of pollen per cubic meter of air, Spring is a challenging time for people with allergies.

In areas with snowmelt, the Spring is also a time to be cautious of fast-moving water and potential flooding. In fact, the National Weather Service reports that the Spring is the second-most common time for flash flooding in the United States.

Creeping Charlie is a tough weed to control, but it can be managed with persistence. Pulling and digging after a soaking rain can be effective, but it's often not enough to completely destroy the weed.

Ground ivy can be effectively controlled with broadleaf herbicides, particularly those containing 2,4-D or triclopyr. Two applications, made at least a month apart, are usually necessary for good control.

In Iowa, the first application should be made in mid to late September, with a second application a month later. This timing is crucial for effective control.

Violets are another common broadleaf weed that can be challenging to control. Digging up small infestations can be an option, but broadleaf herbicides are usually the most practical solution for larger areas.

Triclopyr-based herbicides are effective against violets, and applications can be made in spring or fall. To protect pollinators, mow violets before applying herbicide to remove flowers.

To effectively kill broadleaf weeds in your lawn, you need to start with a solid foundation of general lawn care. Mowing your lawn at the higher end of the recommended range for the turfgrass species in your lawn (3" to 4" for most species) is a great place to start.

This will help prevent broadleaf weeds from establishing in the first place. Fertilizing with nitrogen as needed to maintain a full canopy is also essential. By doing so, you'll create an environment that's less conducive to weed growth.

Here are some key lawn care practices to keep in mind:

By following these general lawn care tips, you'll be well on your way to preventing broadleaf weeds from taking over your lawn.

Maintaining a dense lawn is crucial for preventing broadleaf weeds from establishing. Mowing at the higher end of the recommended range for your turfgrass species (3" to 4" for most) is a good starting point.

Proper fertilization with nitrogen as needed is also essential to maintain a full canopy. This will help prevent broadleaf weeds from taking over.

Low mowing, too little nitrogen, or poor soil can result in a thin lawn, making it easier for weed seedlings to establish. I've seen this happen in lawns that are not properly cared for.

Poor drainage and heavy shade can favor weeds like ground ivy, while compacted sites favor prostrate knotweed. It's not just about mowing and fertilizing, but also about creating an environment that's conducive to healthy turf.

Herbicides should be considered an aid, not a cure, for broadleaf weed problems in lawns. A dense, vigorous turf is the best defense against weeds.

Feed products are often marketed as 'weed and feed' or similar, and they contain fertilizer and herbicide for broadleaf weed control.

These products should be applied in the morning to wet foliage, but be aware that they can be less effective than sprayable products, especially for tough-to-control weeds like clover.

Sprayable products are generally preferred because they can be spot treated only where there are weeds, which dramatically reduces the amount of herbicide applied to the lawn.

To avoid any issues, ensure the prills do not contact ornamental plants, particularly when applying with a rotary spreader.

Managing a lawn can be a challenge, but it's essential to keep it healthy and weed-free. A dense lawn is the best defense against broadleaf weeds, so it's crucial to mow your lawn at the higher end of the recommended range for the turfgrass species in your lawn, typically between 3" and 4".

Fertilizing your lawn with nitrogen as needed can also help prevent broadleaf weeds from establishing. This is especially important if you have a thin lawn, which can be a result of low mowing, too little nitrogen, or poor soil.

To maintain a dense, vigorous turf, it's essential to correct any improper management practices. Proper fertilization, mowing, and watering are key, and herbicides should be considered an aid, not a cure, for broadleaf weed problems.

If you have a small infestation of violets, digging them up is an option. However, if you have a larger number of violets, broadleaf herbicides containing triclopyr are usually the most practical solution.

Here are some common conditions that favor broadleaf weeds:

To achieve good control of violets, two applications of broadleaf herbicide, two to three weeks apart, are usually necessary.
