Espoma Organic Weed Preventer

It's a great organic option made of 100% natural corn gluten meal that kills dandelion from your lawn without using toxic chemicals. It works by inhibiting root development in dandelion seedlings.

You have to apply it twice per year in early spring and fall to stop dandelion from taking over your yard. The slow-release nitrogen fertilizes the lawn to grow a thicker and greener lawn. 

What is a dandelion, and why should you kill it?

Dandelion is a broadleaf perennial weed. Most frequently found in yards, gardens, playgrounds, or anywhere it can find the moist soil. It grows all over the United States and in any soil.

It thrives in full sunlight. The germination starts in early spring, where it finds weak turfs, sidewalk and driveway cracks, or around shadow areas. Its root digs up to 3 feet deep in the soil and can grow 2–18 inches tall.

Many dandelion stems grow from the same plant. Some other weed types, such as Catsear, Chicory, and Hawkseed, look like a dandelion. You must identify these weeds before you start treating them.

Here is how you can identify dandelions in your yard.

  • It grows close to the ground with a rosette leaves arrangement
  • Jagged leaves point toward the plant center
  • Many stems grow from the same plant
  • Hollow stems produce milky fluid when damaged
  • Hairless inward pointed leaves and stems
  • Grows one yellow flower per stalk

Dandelion grows a yellow flowers that turns into a white puffball with many seeds. The dandelion seeds spread out farther with the wind. A single dandelion flower can produce several seeds that will multiply around the lawn at a far greater distance.

So why should you kill dandelion?

Dandelion is a pervasive and robust weed. In fall, it may seem like you got rid of it, but the taproots still survive in the soil. The surviving taproot restarts the weed life cycle in the spring.

Dandelion grows very aggressively and quickly kills thin and stressed turfgrass. It also looks eyesore in a well-curated lawn where it spread across in perpetuity.

What to consider when choosing Dandelion Killer

Pre-emergent or Post-emergent  Herbicide

Pre-emergent works by killing weeds before they even germinate. Post-emergent herbicide works after they took over your lawn. 

Granular or Liquid

Granular herbicide works best when dealing with broadleaf weeds. Liquid herbicides are easy to handle and store but you have to spray it directly on weeds to be effective.  

Organic Herbicide

Use organic herbicide when killing weeds around vegetable gardens as it does not let toxic residues linger in the soil such as when used chemical based herbicides.

Dandelion Growing in Lawn

Here is a dandelion growing in lawn with blooming flower

What are the different types of a dandelion killers?

There are different ways to control dandelion growing in your yard. Let's find out some common types of herbicides and natural means to prevent dandelion growth.

Selective Herbicide

Selective herbicides work great when you only want to kill dandelion without destroying other grasses and plants in your yard. It's safe to use and doesn't harm other plants. It keeps the yard healthy by removing dandelions.

Non-Selective Herbicide

Non-selective herbicides are non-discriminatory and great to use around killing dandelions and other weeds cropping up through cracks in sidewalks and driveways.

You have to be careful when using non-selective herbicides as it will kill every plant that it touches. Make sure you don't apply around the plants that you want to keep. 

Pre-Planting Herbicide

Pre-planting herbicides can be applied when you're developing your yard and have no grass or turfs that you want to keep. It's not widely used among gardeners but used in agricultural and commercial landscaping.

You have to apply pre-plant herbicides over a period of time, usually 15–45 days before you plant or seed. This gives the herbicide to kill any weed seeds or vegetation and start afresh.

You shouldn't use pre-plant herbicide on an established home garden unless you want to start fresh. 

Pre-Emergent Herbicide

Pre-emergent herbicides are effective in controlling dandelion before they even have a chance to germinate in your lawn. It's applied during the winter and fall, which blocks dandelion seeds from germination in spring.

Pre-emergent herbicides aren't very useful once the dandelion has already germinated. You can use liquid or granular pre-emergent herbicides that you apply directly to the soil surface. After application, you have to lightly water the lawn to activate it.

Don't use it if you're seeding your lawn; otherwise, it will kill those. You should wait for 2 to 3 weeks after application to seed your lawn.

We recommend the limited use of pre-emergent herbicides. These tend to leave residue in the soil that takes time to neutralize. 

Post-Emergent Herbicide

Post-emergent herbicides control the weeds that have already grown in your lawn. It works when a dandelion has sprouted and visible.

These are very effective and don't need to be frequently used. You can apply it once and wait for the dandelion to die. If there is any leftover growing dandelion weed, you can reapply.

The organic post-emergent herbicides are also available. It's useful on a dandelion, but its effectiveness is limited.

For a highly weed growing area, the chemical-based herbicide is most effective. You have to spray it over leaves and stems. 

Organic Herbicide

The chemical-based herbicides are toxic and linger far longer in the ground. You have to keep pets and children away from the yard for a few days after application.

If you want something more eco-friendly, you can consider using organic herbicides. These are effective on broad-spectrum weeds such as dandelion but may not cover other weed types.

You can use it safely in large yards and don't have to worry about keeping kids and pets away. Killing dandelions in lawns with vinegar is an excellent DIY organic herbicide.

You shouldn't overuse it as it can change the soil's acidity level that may impact other plants' health in the yard. You can safely use it in a moderate amount on the lawn. 

Granular vs. Spray Herbicide types

When you look for herbicides, there are two forms that you can buy. It can be either a granulated formula that you sprinkle around garden plants or a liquid concentration you use with a weed sprayer.

Most pre-emergence herbicides are granular that you can spread on lawn and garden beds. Some brands also add nitrogen-rich fertilizer. It inhibits broadleaf weeds while providing nutrients to grass turfs.

Spray herbicides come in both selective and broad-spectrum solutions. You have to spread it directly on the dandelion and may need reapplication to kill the dandelion permanently.

Due to their liquid forms, these are easy to store and apply. You can use it around driveways or other hard surfaces with cracks where you see dandelion growing. 

Here is a helpful video on getting rid of dandelion from your lawn. 

How to prevent dandelion from regrowing?

When it comes to preventing dandelion from regrowing, there are few options that you can take. First, you should remove any dandelion when the first time you see it growing on your lawn.

For a tiny number of dandelions, you can physically remove it by pulling it manually. You should lightly water the area a day before to dampen the soil around the dandelion.

You can start pulling it in the early morning when the ground remains moist. You must remove the dandelion with its full root. You can push the nearby soil around dandelion by using weed removing gardening tools.

To make the job more comfortable, you can use a weeding knife and strip the dandelion base. Clear the soil around it and gently pull the rest of the roots with your fingers.

Don't pull it hard; otherwise, it will break the root that will give it a chance to regrow. If roots feel stuck, use the weeding knife to remove more soil around them and gently pull out the entire taproot.

After you have cleared your lawn from dandelion, you can prevent it from regrowing by focusing on improving your lawn's overall health. A vigorous and robust lawn is less susceptible to dandelion and other weed types invasion.

A healthier and stronger turfgrass prevents other weeds from taking hold in the ground. You can follow these best practices to improve lawn health.

  • Keep grass healthy with a proper fertilization schedule. For example, if you have grass like fescues, fertilize them once in the fall. For Zoysia and Bermuda, you should fertilize it in spring.
  • Don't cut the grass too short. You can mow grass at the height of 2 to 3 inches. This allows the grass to protect itself by stopping the sunlight from reaching the shorter weeds. As a general rule, you shouldn't cut grass more than a third of grass blade length at a time. The longer grass prevents it from drying out too quickly.
  • Encourage deep and healthy grassroots by watering deeply but infrequently. A healthy lawn needs 1 -1.5 inches of water per week, including rain.
  • Prevent bare spots on the lawn for a long duration. It gives the weed to take hold and start growing. You should overseed the uncovered areas in the fall to allow them to start growing in spring.

If you follow the above methods, you can keep your lawn healthy and stop weeds and dandelions from regrowing in your yard.

Dandelion Killer—Buying Guide

Selecting the right dandelion herbicide isn't as simple as picking a general weedkiller. You're free to choose what may suit your needs, but you risk purchasing something that may not work for your yard.

Instead, when browsing it, you'll want to be aware of a few critical things in mind to ensure that you find the right product for your yard. 

Herbicide Effectiveness

The effectiveness of herbicides depends on type and chemical concentration. Some herbicides may take much longer to give you the desired result.

Some herbicides aren't weatherproof as their effectiveness gets diluted with elements like rain or bright sunlight.

Choosing a weatherproof herbicide that can be effectively applied in harsh weather is a great option to consider. 

Potency

Generally, you'll have to mix herbicide with water to dilute it before spraying it on dandelions. A highly potent herbicide means you can dilute the solution to cover a larger area. This saves you the amount you need to apply to get rid of dandelions.

Multipurpose Weedkiller

If you're looking to control other weeds, including dandelion, consider choosing a multipurpose weed killer solution.

Usually, if you have a problem with broadleaf weeds, select an equally effective herbicide on other weed types. This will negate the need to purchase multiple products.

Granular or liquid herbicide

You have an option to buy weedkiller in either granular or liquid state. There are pros and cons to each. Granular form herbicides are easy to apply, but there is a risk of pets consuming them.

Liquid herbicides are also easy to apply, but you will need a weed sprayer to get started. However, if you've got a pet, I would recommend choosing liquid herbicide as there is less risk of pets eating it. 

Herbicide application temperature

Some chemical herbicides will be effective only at a specific operating temperature. For example, most weed killers are more effective between the 90–100 degree temperature range. It's worthwhile to consider an herbicide that suits your outdoor temperature requirement. 

Long-lasting effect

A herbicide that lasts long, effectively suppress the dandelion growth. Most manufacturers label these types of herbicides as persistent and non-persistent. Choose the one as per your needs.

Does dandelion killer work?

If you're skeptical about whether it will work on your lawn, the answer is "yes." But you need to check the label and buy a broadleaf weed killer type herbicide to control dandelion.

To get the best possible result, follow the manufacturer's instruction, use the proper dose, and apply it as recommended. In an extreme case, you may need both selective and non-selective herbicides to handle the dandelion growth.

For higher potency, choose herbicide containing glyphosate as it destroys nearly every plant it comes in contact with. You should be careful when using around other plants that you want to keep. 

Dandelion Flower With Weed Killer Application

You can apply dandelion herbicides directly on the plant

When should you apply dandelion killer?

Dandelion killer works best before the dandelion starts flowering. You should aim to apply it when you see a dandelion plant growing.

You can choose both pre-emergent or post-emergent types of herbicides depending on when you're dealing with this problem.

It may take 1–3 weeks after herbicide application to altogether remove dandelion. You may have to reapply if you find any leftover or regrowth in the lawn. For dandelion growing in cracks of sidewalks and driveways, choose selective herbicides.

As preventive maintenance, you can spray it in late spring and early fall. This is the best time to apply it to control all broadleaf weeds. 

How should you apply dandelion killer?

When you're ready to apply dandelion killer, spray it around the roots. A fully grown dandelion has up to a 10-inch-long taproot. If you don't damage the root, the dandelion will respawn and further spread in the yard.

Follow these steps to apply it safely:

Step 1: Herbicides are toxic. You must wear proper protective clothing such as gloves and eye google. Also, ensure that pets and kids aren't around when applying.

Step 2: If you're using liquid herbicide, prepare the pump spray, and add herbicide. Dilute it with water as per manufacturer instruction.

You can apply between 3.2 and 4 pounds of weed killer per 1,000 sq ft and don't go over the maximum annual rate of 8 pounds per 1,000 sq. ft.

Step 3: Spray the herbicide directly on the dandelion roots and let it dry out. Keep kids and pets away while the yard dries out.

Herbicides may take 30 to 60 minutes to dry and become resistant to water. Some slow-release herbicides may take up to 8 hours.

You should stop mowing the lawn couple of days before and after application. You shouldn't water your lawn at least 24 hours of herbicide application.

Step 4: You may see dandelion leaves getting withered and dried out from 24 hours to two weeks. This depends on the weed killer type you used.

Step 5: If you're using a pre-emergent herbicide, wait three to four days after application to reseed the lawn.

Step 6: If you're not sure how much herbicide to use or how much to dilute, you should opt for a less aggressive but slow dandelion herbicide. This way, if you make a mistake, you won't ruin other plants and grass in your yard.

Step 7: When you're ready to spray, move back and forth in parallel, then apply in a perpendicular direction to give full coverage in your yard.

Step 8: To prevent dandelion's respawning, fill the dugout dandelion hole with per-emergent herbicide. It will kill any dandelion seeds buried in the soil. 

The Bottom Line

The above list is the top-performing dandelion killer that one can find on the market today.

I used some of those with great success. You can choose the one depending on your needs, and I'mconfident that you will have great results.

Make sure you read the instructions before applying. Many people get disappointing results when they don't follow the instructions properly.
