The Buyer’s Guide

Natural or chemical components?

Organic products are quite powerful and they’re usually non-toxic. They’re not going to threaten your relatives or some animal that’s going to happen in your yard. They often happen to be biodegradable, which is beneficial for the climate.

However, they are still not as strong as chemical-heavy remedies. Often enough, conventional weed killers are only vinegar-based products. For minor issues, this may be a good strategy, but when it comes to heavy infestations, they might not be willing to cope with dandelions.


The volume of the bottle with a weed killer defines the approximate amount you may spread over your lawn. The larger the bottle, the higher the price you typically should pay per ounce. Of course, this isn’t a clear and quick guideline, but it’s a generalization that you can rely on to save money.

For e.g., a gallon-sized jar can cost more than an ounce, but it may cost less than four quarters. If you expect a potential need for a weed killer for dandelions, it’s far more advantageous to purchase a larger bottle.

Volume aside, the dosage size is the second most important element in assessing the performance of the herbicide. Very strong plant killers will do a lot with a couple of tablespoons of solution. Meanwhile, cheaper alternatives can need half a bottle to produce the same effect.

So, it is better to invest in larger bottles with the concentrated product.

Rain-proof functions

A herbicide is inevitably continually exposed to the elements. Although there’s nothing you can do to full immunization against the world, there are certain features that can aid.

Waterproofing is one of the easiest strategies to guarantee that the substances you put down really have the opportunity to do what they are meant to do. The strongest choices will be waterproof within an hour of spraying.

Others can take several hours, or they can never enter a waterproof condition. If you live in a very dry environment, you can be able to get away with one of these inferior goods. However, most people are going to prefer something that’s going to stand up well against the stream.

The appropriate climate

Hot weather is a no-no for some herbicides. The higher the temperature, the worst the product would turn out. Typically, the range is about 90-100F. High enough that most people are only going to be great on an ordinary summer day.

There are still cases, though. For example, a few products are still effective when the weather temperature is about 80F. These choices would be practically ineffective in hotter climates. So, the greater the temperature threshold, the sooner you may need to use a herbicide.


You will need to ensure sure it can be used on all sorts of grasses and weeds. Other people can just destroy those kinds of weeds. You’re going to need to verify if you can use it on the particular weeds you need to get rid of.

The only thing you should do is to invest in a multi-purpose killer. It should be mentioned on each label if it should be used on all kinds of weeds or just some of them. You’re going to want to check at some that are beneficial with all sorts of weeds. The following articles can help you locate the right tool to fix your cannabis problems.

Final thoughts 

Hopefully, right not you will be able to save your beautiful lawn from dandelions with one of these weed killers. However, if you’re already on the fence, you may want to review a few of the highlights on this guide. Budget shoppers have found these weed killers quite interesting, for sure. If your aim is to save a little money on this buy, you may want to go for one of the Roundup items.

Dandelion is a very insidious weed. One dandelion flower can gradually spread throughout the lawn. Its seeds spread well over long distances and germinate on any uncovered plot of land, which is why there are so many of them.

The major reason for their speedy growth is their roots: they are very powerful (they can reach up to 12 inches), but more brittle than other plants. That is why it is difficult to remove dandelions completely from the soil. If you want to destroy these unwanted plants, you have to act fast as soon as you notice the first dandelion. Especially for you, I have tested a few different weed killers that can cope with these stubborn dandelions.

There are different ways to control the growth of dandelions:
Chemical herbicides should be used in autumn. The fact is that at this time of year the plant is preparing for overwintering, and nutrients from the top go to the root. If you poison the plant, the herbicides go straight to its root system. For this reason, it is best not to mow the lawn and the dandelions on it a few days before the application, it is best to do so afterward;

Another powerful remedy to destroy the root system of dandelions is salt. If you sprinkle salt on flowers, after a while there is only a dark spot left. But do not overdo it: salt can also affect useful plants. You should apply it selectively;

How to prevent dandelions from appearing?

A good way to fight dandelions on the lawn is to prevent them from appearing. You need to take good care of your lawn. There shouldn’t be any bald spots on it: dandelion is a weed that germinates quickly and easily in the unprotected soil. Once a week, the lawn should be mowed (6-8 cm). You can do this with a variety of lawn mowers or with your own hands. Weeds will not appear if the soil receives enough moisture and nutrients. A thick layer of turf also prevents dandelions from appearing.
