What is Dandelion?

Dandelion is a flowering herb that is native to Europe. It is found throughout mild climates of northern hemispheres of North and South America, as well as other continents. The most common variety of dandelion is Taraxacum officinale because it grows in many parts of the world.

Dandelions have sharp leaves that resemble the teeth of a lion. Dandelion seeds appear as little parachutes and are easily carried by winds and spread all over and reproducing to grow new dandelions.

Some species of dandelion occur as flowering herbs, while other species are weeds. However, both species are edible, and its flower, roots, stem, and leaves have been used for different medicinal purposes to treat some ailment. It is important to note that dandelion pollens cause allergies to some people.

When used as food, dandelion is used in soups, teas, and wine. It is also used as salad green while its root is roasted and used as a coffee substitute.

Why Should You Kill Dandelions?

Do Dandelion Killers Work

Dandelions at their young age are pretty and add great aesthetics to a home’s landscape. However, they grow older and begin to create a nuisance in their host environment.

Although some people oppose killing dandelions stating that people who kill dandelions starve and kill bees. These statements are fallacious, and here a few reasons you should kill dandelions.

Dandelions are fast-growing plants

When dandelion plants get mowed, they grow back almost immediately and start producing flowers. That means that bees do not get denied of their meals, as most proponents of dandelion say.

Dandelion plants, just like other plants, like to grow more plants. To grow more plants, dandelions develop more flowers, and these flowers go-ahead to develop dandelion seeds. These seeds help in the proliferation of dandelion plants as they are easily carried by winds.

As a result of its speedy proliferation, you should really consider getting rid of dandelions when they are overgrown and creating a nuisance.

Dandelions have well-developed taproots

Dandelions have well-developed taproots, which makes them very resilient and unaffected when you attempt to naturally get rid of them by either cutting its leaves or mowing the plant. Until you get rid of the taproot with a good dandelion killer, it won’t re-grow.

Their well-developed roots are another reason you should kill dandelions with any of the best dandelion killers we would be recommending below.

Any other means of getting rid of dandelions would support the regeneration of the plant parts. And if you have one dandelion, you probably have many of them in your garden or where ever you have growth space.

Do Dandelion Killers Work?

People often ask if dandelion killers really work, and the reason we think they ask this question is because of the period in which they used the dandelion killers. Dandelion killers are best used to kill dandelions when the dandelions are still yellow.

At their yellow stage, they haven’t started producing seeds yet. Attempting to kill them when they have begun producing seeds may be futile as their seeds may have started spreading. Their seeds spreading imply new growth, and this would hamper the effect the dandelion killer used.

For clarity sake, dandelion killers work. Some of the dandelion killers work specifically only on dandelions, killing only dandelions.

While some other types of dandelion killers kill dandelions and every other thing surrounding the dandelions, meanwhile, there are chemical mixtures that kill dandelions and a combination of common weeds.

There are several options of dandelion killers, unlike other weeds that do not have a single mix for their control and eradication.

Some dandelion killers are quick to action while others are slow to act but eventually do the job. Listed below are some of our top choices of dandelion killers you can choose from.

Dandelion Killer Buyer’s Guide| What to Consider While Buying One

What is Dandelion

In order to buy the best dandelion killer that suits your personal needs, you must know what to look out for. There are varieties of properties that make for a good dandelion killer.

Outlined below is the information that will guide you in choosing the best dandelion killer for your lawn.

Organic Vs. Chemical

There are both organic and chemical dandelion killers, and each comes with their own benefits and flaws.

An organic killer kills weeds at a very slow pace and sometimes requires to be applied a couple of times to take it. However, it causes no harm to anyone or anything that comes in contact with it- kids and pets inclusive.

Meanwhile, a chemical killer eliminates weeds at a fast pace, but it does cause harm to kids, pests, and some vegetation.

Pre-Emergent vs. Post-Emergent

Once you have chosen to buy an organic killer or chemical killer, the next option is to choose whether the killer should be pre-emergent or post-emergent.

A pre-emergent killer aims to prevent the growth of dandelions. Thus it is applied on the lawn before the emergence of dandelions.

They are usually either in liquid or granular forms and are applied on the lawn and then watered down into the soil to activate the active ingredients against the growth of dandelions.

Meanwhile, post-emergent killers contain ingredients that halt the growth of dandelions. Some people use this killer alongside other chemicals that discourage the re-growth of dandelions. Hence, they have a mix of chemicals that halt the growth and re-emergence of dandelions.

To ensure that the dandelions do not grow back, ensure to saturate their base, leaves, and stems with the chemical.

Selectivity and Persistence

Selectivity talks about the mode of action of the killer. A selective killer kills just dandelions and does not affect any other plant within its reach, while a non-selective killer kills everything it comes in contact with.

Persistence describes how long a product would remain active. Products that have a lasting effect and discourage new growth of weeds are described as Persistent Products, while the products that do not stay active after a while and allow new growth are described as non-persistent products.

Depending on personal preferences, you may wish to buy either a selective persistent product or a non-selective non-persistent product.

The durability of the Product

Some products are used in all kinds of weather, while some are used only when the weather is either rainy or sunny. Knowing the kind of weather a product endures will enable you to use the product at your own convenience.

You can find out the durability of a product by reading reviews of the products, checking the product’s manual or by contacting the seller. Make sure you know this before buying a product to save yourself time and money.

Here, you also check the type of weed the products work well against. If you are not sure of which to buy, simply go for a multi-purpose killer. It gets rid of all weed types, but you can also go for a specific type of product.

How to Prevent Dandelions in your Garden?

Best Dandelion Killers

Dandelions are prevented by spraying or sprinkling pre-emergent herbicides on lawns. A pre-emergent herbicide prevents dandelion seeds from germinating and should be applied in late winter for optimal effectiveness.

Another way of preventing dandelions is by ensuring that the dandelions do not form seeds. Once the seeds appear, the dandelions will multiply exponentially and would be hard to control at that level. So, to prevent its growth and spread, take action before the emergence of its seeds!

How to Get Rid of Dandelions with Herbicides

To get rid of dandelions with herbicides, there are two herbicides that get the job done. The first herbicide is selective broadleaf, while the other herbicide is non-selective.

A broadleaf herbicide kills only broadleaf weeds like dandelions. Broadleaf herbicides are good for killing dandelions that grow in lawns as the herbicides do not attack grasses but dandelions.

Meanwhile, a non-selective herbicide removes spot dandelions, that is, dandelions that grow in walkways and in flower beds.

Herbicides work effectively against dandelions when the dandelions have not developed flowers yet. Dandelions become more resistant to herbicides when their flowers have emerged.

The Science Behind Herbicides

Herbicides are chemical products that are made solely for the purpose of killing unwanted plants and herbs. Scientifically, herbicides are either broad-spectrum in action or selective in action.

Broad-spectrum herbicides are scientifically made to kill anything green that comes in contact with it- this includes both wanted and unwanted plants.

A majority of organic herbicides are broad-spectrum in nature, with only a handful of chemical herbicides being broad-spectrum in nature.

Selective herbicides are scientifically made to kill only a targeted group of unwanted plants. Selective herbicides are usually not as potent as broad-spectrum herbicides and require multiple applications for results to appear.

Organic selective herbicides kill just weed seeds and not living weeds, but some chemical selective herbicides kill both weed seeds and living weeds.

How Herbicides Work

Herbicides, whether broad-spectrum, selective, organic, or chemical works in one of these three ways:

Pre-plant Herbicide

Herbicides used here are sprayed on soils at about 14 to 45 days before planting seeds or plant and such herbicides are used in grand agricultural settings.

The herbicides work by getting rid of any weed that may be in the soil or getting ready to appear. However, it sometimes causes wanted plants grown not to develop accordingly. But this drawback is overcome through rapid plough and spraying.

Pre-emergence Herbicide

Pre-emergent herbicides work to prevent weed seeds from germinating and spreading through a garden or lawn. They do not eliminate grown weeds and would have no effect on weeds whose seeds are developed already. They are available in either granules or sprays.

Post-emergence Herbicide

Herbicides in this category kill already grown and developed weeds. They weaken the weeds until the weeds die off. Organic post-emergent herbicides target just young weeds, while chemical post-emergent herbicides effectively kill both old and young weeds.

Frequently Asked Questions

Are dandelions weeds?

Yes, dandelions are weeds because they compete for resources with other wanted plants.

Are there dandelion killers that are all-natural products?

No, there aren’t. Any product that is labeled as a selective dandelion killer will use chemicals to kill the weeds.

Which weed killer is best against dandelions: liquid or granular?

Each of them has its own drawbacks and benefits. A liquid weed killer would be applied using a sprayer and would adhere to the dandelion parts and penetrate the soil easily.

However, it takes time to mix and apply. Granular weed killer is sprinkled on the soil and some parts might get blown away as it does not adhere to any weed part, but it is faster to apply.

When is the best time to spray dandelions?

The best time is early springs when the dandelions are just appearing and still small. Also, late fall is a good time too.

How long does it take dandelion killers to work?

It typically takes dandelion killers about 1 to 3 weeks to work because the products vary in chemical compositions and the weeds vary in species as well. Some killers take about just 3 hours to work.

Is my pet safe around my yard after I use dandelion killer?

No, dandelion killers are toxic to pets and kids. Pets should be kept away from areas that have sprayed or spread with dandelion killers until the chemicals dry up.


Having gone through this entire article, you are probably looking for the best dandelion killer and it is our hope that your needs were met with the different types and brands of best dandelion killers we outlined.

Every dandelion killer mentioned here are either specific in action against only dandelion or against dandelions and other weeds and have been tested and proven to be effective.
