Dandelion Killer – My Choice & Ultimate Guide

Whether you’re a lawn enthusiast or a gardener, there is a high-time chance you have experienced the level of frustration one does at the sight of those bright yellow flowers. You might even feel a sudden urge to cuss. And be assured, it is for an upright, noble reason.

Dandelions not only damage your garden by killing nutrients, grass, and other plants in it but also by sapping water. Owing to their far floating and fluffy seeds, they are challenging to control. But getting rid of them is in your hands, and I have got everything to help you battle these uninvited agents.

Below are some products that are absolutely efficient and effective in combating dandelions. Let’s have a look at them.

Dandelion plants are hard to get rid of as they grow fast and come back after every year. And hence, they need to be eliminated annually. Of all the dandelion killers in the market, I have selected these TOP 7 for you.

Scotts Turf Builder Weed and Feed

The Scotts Turf Builder Weed and Feed is your best bet for getting rid of dandelions, clovers, and other weed plants. It works by feeding or thickening your garden. In this way, the grass becomes lusher and pushes out weeds and dandelions. It works by causing vegetation or nutrients to grow in place of the weed plants such that weeds are disabled to regrow from that spot. It kills weeds of all kinds, whether visible or invisible and makes your garden look more green, strong, and plush.

  2. Nourishes lawn
  3. Selective herbicide

More Power

The new Scotts Turf Builder is 2× more powerful than its previous formula. Its weed gripping technology pulls out all weeds, whether visible to the eye or not, altogether. It wipes out every last dandelion or clover in your lawn. It comes in a very subtle packaging of bright yellow and green colors. Also, it is absolutely cost-effective and is worth the price. It is constructive in clearing out almost fifty (50) different types of weeds. Its regular use crowds out future dandelions and weeds, which means you don’t have to worry about dandelions coming back no more. Amazing, no?


It comes in two variations of 5,000 sq. ft. or 15,000 sq. ft. You have a better chance of getting your hands at the right product if you know the correct measurements of your lawn. To thicken your lawn with Scotts Turf, use a Scotts broadcast, rotatory spreader, or drop in a damp lawn in any season.

Budget Benefit

Looking for a handy dandelion killer on a budget? Then I’d say the Scotts Turf is the best deal for you. Only in the case of 15,000 sq. ft. will you have to spend some extra bucks. But with such a quality product, the money’s worth it.


The drawback Scotts faces is its weighty container. To elude extra effort, you might want to transfer the contents inside the Turf Builder into a lighter container. Also, it doesn’t work for grass of every type. It may go along with turf grasses but not with grasses like Saint Augustine grass, Dichondra grass, Floratam, Lippia, Carpetgrass, or Bentgrass lawns.


Scotts Turf is a 2 in 1 herbicide. Not only does it kill dandelions, clovers, and other weeds but also nourishes the grass and gives it life. Also, it comes with a money-back satisfaction guarantee, which makes it all the more worthwhile. I totally recommend you to buy it.


Preen Extended Control Weed Preventer

The ideal way of preventing weeds and dandelions from entering your lawn is by never letting them grow in the first place. And that is made possible with the all-new Preen Extender Control Weed Preventer. It keeps the landscape beds and gardens free of dandelions and other weeds for up to 6 months; what a relief! It can be used in up to 600 kinds of perennial flower beds, ground covers, and xeriscape settings. However, Preen is only a weed preventer and not a weed killer. Therefore, it will stop new weeds from growing in the future as it is a pre-emergent weed preventer, but it can’t kill weeds that are already active.

  1. Comes in a handy container and a scoop
  2. Works in every season
  3. Offers 6 months of complete weed control
  4. Easy application


  1. Doesn’t kill previously existing dandelions or weeds
  2. Not pet-friendly


Preen comes in a yellow-colored jug-handled-container. It also includes a flip-top cap and a scoop, which makes the application easy and smooth. Preen is well known for its fighting qualities as it not only fights against dandelions, white clovers, oxalis, filed bindweed, chickweed, but many others.


Preen’s application is awfully simple. But before applying Preen Extended Control Weed Preventer, you will have to eradicate any previously existing weeds. Then to apply the product, flip it open and begin sprinkling the granules on the mulch according to the rate on the label. Either apply the product to damp soil or water the mulch after application (In case of no water, work the granules into the soil with a rake). This activates the product, and it structures an indiscernible barrier at the top of the mulch, which prevents weeds from sprouting.

Time Period

Two applications of Preen give you a whole year of less lawn maintenance. The second application can be performed at any time after 2-6 months of the first application.


If your primary mission is to remove active dandelions, this might not be the product for you as it doesn’t kill active weeds but simply prevents future dandelions and weed growth. Other than that, it is totally recommended by me.


It comes in four different sizes, and depending upon the size; it ranges in price. And it is a bit costly, but with all the specifications it offers, the price is genuine. Also, it comes with a money-back satisfaction guarantee.

Buyer’s guide

A dandelion killer works by eliminating dandelions from your lawn. And keep in mind to purchase a product that removes dandelions thoroughly as even a small part of dandelions taproots can cause the entire plant to regrow, and please know that dandelions grow extremely fast.

Its petals seem like hairless toothed edges and turn white once they mature. Dandelion seeds rest in the center of the plant. And these seeds will spread across your lawn with a single wave of air. Hence, they mushroom very quickly.

Dandelions can grow up to 3-10 inches under the mulch. And as for the fact that they begin growing even if a bit of their taproots have been left behind, you need to remove the dandelion as soon as it comes to your notice. These are difficult to remove and require a tremendous amount of effort and time.

However, this task has now become effortless owing to dandelion killing products in the market. They are easy to use, work immediately, and show fast results.

The first thing to consider before purchasing a dandelion killer is to know your lawns’ type and its area. Then look for a product that suits all your needs, including budget, effort, and quality of the product. The above-mentioned options include inexpensive and expensive products. Therefore, choose the one that your heart vouches for.


How does dandelion killer work?

A dandelion killer works by terminating a dandelion up to its roots. After the dandelion is dead, you can easily pull it out of the mulch. The product must be selective, or else it would kill any plant that comes in contact with it.

How to use dandelion killer?

Simply spray the product upon the dandelions if it is selective. If the product is non-selective, handle it with care, or any plant that comes in contact with it will die. According to the area of your lawn, add approx. product to a water gallon, and it's ready to use.

When to apply dandelion killer?

If you're using a pre-emergent weed killer, apply it in the winter season for articulate results. That is because pre-emergent dandelion killers are to be applied before dandelions' germination so that they don't grow at all. With a post-emergent dandelion killer, either use it in spring or early fall. They can be used on actively growing dandelions. However, in both cases, follow the instructions on the container keenly.

How long does it take for dandelion killers to work?

A dandelion killer typically begins working in 24 hours. However, a dandelion may die in 2 days or 2 weeks.

Why homemade dandelion killer is a bad idea?

Homemade dandelion killers are not as effective and powerful as chemical herbicides. There are chances that it might work slower than a chemical herbicide or not work at all. Therefore, it is better to stick to herbicides.

Is dandelion killer bad for dogs and other pets?

Dandelion killers can be absolutely toxic for animals. And lead to diseases like nausea, dehydration, unconsciousness, depression, and unfortunately, even death. Therefore, to avoid such grievous outcomes, select a dandelion killer that is kids and pet safe.

Is it safe for grass?

Most dandelion killers, when sprayed, kill the grass along with the dandelion. But to avoid this, you can use a broadleaf herbicide that kills the entire plant and its taproot without harming the grass in the least.


Dandelion is something that is loved by children and despised by elders. If you’re a gardener, you know the difficulty of dealing with dandelions. However, in the present era of technology, there is a solution to everything, and the same is the case here.

Hundreds of varieties of dandelion killers are available in the market that are budget-friendly, eco-friendly, and work well. But it’s human nature to find the best in everything. And in finding the best dandelion killer, I thought I’d help you out.
