An Ultimate Buying Guide For The Best Dandelion Killer

Types Of Dandelion Killer

There are several types of dandelion killers that you need to know before making a purchase decision.

Selective Herbicides

This product would be the best spray for dandelions in your garden as it kills dandelions but does not harm other plants and keeps them safe and sound. As its name suggests, it selectively looks for the leaf weeds and eliminates them rather than destroy everything on its way.

Non-selective Herbicides

In contrast, the powerful non-selective type would be a great choice for eliminating all the leaf weeds in your sidewalks or driveway. It can provide you with a deep and comprehensive clean, bringing the clean route back for safe traveling.

How to remove dandelions from your garden?

The most conventional way to get rid of dandelions is by hand. If the pulling is too difficult, you can use additional support from broadleaf herbicides.

Moreover, the dandelion removal tool is always an available and helpful tool for gardeners. There are grass killers, such as claw weeder, weed extractor, weed torch, or bend remover for optimal weed control.

Another highly effective method for dandelion removal is herbicide application. It would be best to apply herbicide on a dry and sunny day. Now, get your weed killer ready!

  • Remember to wear protective gloves, goggles, and clothes during the process, as chemicals can be harmful when exposed to the skin.
  • Mix the chemicals in a pump sprayer with water and additional substances printed on the instructions.
  • Locate the dandelions and specifically spray the weed killer mixture onto them. Then wait for it to dry out. As the weed killers take effect, the dandelion’s foliages start to turn brown and gradually die.
  • When they have completely withered, you can pull out all the remains and start a new plant session after three days.

Important Features Of The Best Dandelion Killer

Organic or Inorganic

The best spray for dandelions is usually divided into two categories: organic and inorganic models.

The organic dandelion killer is completely safe and eco-friendly for children and pets. On the other hand, it would take longer to get rid of dandelions and require a greater application compound so it might be suitable for lawns enduring a smaller growing level of dandelions.

In terms of the inorganic type, the effect is more noticeable and significant. It could take effect much quicker, and you can see the results pretty much instantly.

In return, this dandelion weed killer type can be hazardous for pets and children. It would be best to wait for the chemicals to dry or wash away before letting them go and play in the garden.

Pre-emergent or post-emergent

A pre-emergent herbicide will prevent dandelions before they develop into full-sized plants. The product would eliminate those weeds from their seeds.

You will take full prevention for your plants, limiting the dandelion growth and killing it before it causes any damage to the lawn—the best season for pre-emergent application is winter and autumn.

However, bear in mind that the product would not be effective when the plant has already been formed into shape.

It works opposite to post-emergence, which kills existing plants. It is an ideal choice for deep infestation control. However, post-emergence is unable to affect the seeds.

Depending on the situation, you can choose either type. There are also all-in-one lawn weed killers as an option if you are too confused to determine one final decision.

Get to know more about applying post-emergent herbicide:

Effectiveness And Durability

The best dandelion killer for lawns should show noticeable and real effects, especially if the product is equipped with weatherproof features. The effect can decrease significantly due to the impact of external weather elements.

For that reason, you should seek products with both great effectiveness and additional weatherproof characteristics.


The quantity of the mixture determines the price. The greater its volume, the more money you can save for each ounce. For example, one gallon can be more expensive than a quart but much more reasonably priced than 4 quarts in careful calculation.

If you choose what fits your budget, purchases for a gallon would be a wiser decision to make. You can set aside some extra bucks for another investment.

Dose size

A strong dose sized herbicide would be the best product to kill dandelions. You can achieve the desired results with only a couple of tablespoons of the mixture. In contrast, ones with weaker dose size can take up to half a quart to reach the same target.

If you want to check whether your purchase is worth the money, you should pay attention to the dose size information printed on the labels.

Liquid or Granular

The best weed killer for dandelions usually comes in liquid form placed in a sprayer for application. There are also granular and pellet models for you to choose from. Granular killers are quite easy to apply, but they can be harmful to animals.

For that reason, pet owners should consider it carefully before finalizing the buying decision.


This feature is vital if you are using selective herbicides. The persistence will inform you how long they will be active after application.

If the effect is long-lasting and prevents further growth of dandelion, the product is qualified. Otherwise, it is considered a non-persistent type.

Temperature threshold

Some dandelion killers do not work well with the heat, so you should check whether the product is suitable for the region or not.

The temperature threshold ranges from 90 to 100 degrees Fahrenheit. However, some brands only work well at the maximum temperature of 80 degrees.

Therefore, it is necessary to consider this feature carefully before buying.

Multipurpose weed killer

If dandelion or broadleaf weeds are not the only types of plants you want to eliminate, the multipurpose weed killer is a great option.

With this kind of product, you will not have to buy another weed killer for killing other kinds of grass.


Additional features are usually one product’s selling points. It could be a hose port or effortless pumping. Some products even come with a measuring syringe for precise spraying.

In conclusion

All in all, the Scotts TouchUp Weed Control is the most versatile and highly qualified to become the best dandelion killer from all the detailed reviews. It is highly effective in the eliminating process and completely safe for the lawns.

With the step-by-step buying guide, we hope that you will sort out an ideal measure for yourself to bring back home the impeccable dandelion killer.
