Things to Know Before Buying the Best Dandelion Killer

Things to Know Before Buying the Best Dandelion Killer

Now that you know what the top dandelion killers in the market are, it’s time that you know the following before placing your order or making your purchase:

Requirement of Temperature

You will find some dandelion killers in the market that need the weather to not be too hot. You have to be very careful while using this type of weed killer. If the temperature increases, the effectiveness of the solution will decrease. Typically, the threshold is around 100 degrees.

However, this is not always the case. You will come across a lot of dandelion killers that have a temperature cap of around 80 degrees. These are best to use in cold climate areas and can be useless if you use them in hot areas.

When you buy a dandelion killer, go for the one that has a high-temperature threshold. This way, the product will be effective even if the weather gets warm substantially.

The Volume of the Product

 If you buy a large container, the price per ounce will automatically decrease. Although it’s not always the case, it’s a common conception, and manufacturers often follow it.

Chemical or Natural

You need to be sure what type of dandelion killer you want to use in your yard. Do you want the chemical ones or the organic ones?

Both types have their own upsides and downsides.

If you’re someone like me who likes to go with the organic option, know that they are non-toxic and eco-friendly. On the contrary, chemical weed killers are made with toxic chemicals. They are not good for pets or kids to be around. And they are not good for the environment.

However, compared to their organic counterpart, the chemical weed killers work faster.

Types of Application

You get to buy most dandelion killers in different packaging and forms. And each form has a different application method.

You need to decide which form of dandelion killer you would like to use in your yard and buy it according to that. Some common types of applications are concentrate, spray, and pellet.

Now, what if you go for pellet form?

Well, this form of weed killer contains everything – from small granules to fine mulch-like products. And you need to use your hand to spread it in your yard.

If you go for spray products, you can attach them to a garden hose with the help of a nozzle.

And if you go for a concentrated form of weed killer, you need to mix it with water first and then pour it into a sprayer to use it on weeds.

Pre-emergent or post-emergent

The dandelion killers that are pre-emergent stop the weed before it germinates.

The post-emergent ones kill the existing weeds that are there in your yard. This variety is more toxic than the pre-emergent ones. So make sure to take safety measurements.

Durability

Because of weather conditions, lots of products limit the time of their effectiveness. In order to be sure which weed killers can work on all weather conditions with the same effectiveness, read the instructions that come with the product. Also, read the reviews of the other users.

Persistence or non-persistence

This suggests the activity rate of the product. The persistent ones are those that give you a long-lasting result and prevent new weed growth. On the other hand, the non-persistent ones don’t stop new weed growth.

Selective or non-selective

Selectively weed killers means you want to kill just the targeted dandelions, and you don’t want to affect its surroundings. However, the non-selective ones kill all the plants that you sprayed on.

FAQ’s

Here are some FAQs on dandelion killers with their answers:

Q1. How can I kill just the dandelions and not the grass?

Ans. Go for “selective” dandelion killers, as they will target only the weeds and not the grass in your yard.

Q2. What are the features of a good dandelion killer?

Ans. Effective dandelion killers are selective, persistent, and offer excellent durability.

Q3. How can I kill dandelions naturally?

Ans. You may come across certain products that use only organic ingredients, for example, natural acid and vinegar.

Q4. What is the best way to get rid of dandelions from my yard?

Ans. If you want to remove dandelions from your yard, you can do that by hand. However, in order to kill them and prevent them from growing again, it is best to use a dandelion killer.

So, which dandelion killer are you getting for your yard?
