Choosing the best weed killer is essential if you want to benefit from a luscious garden all year round. Aside from helping it remain beautiful, the right weed killer will help your flowers grow more fully.
Unfortunately, today, there are thousands of different types of weed killers to choose from, all of which have a variety of advantages and disadvantages. Before you can purchase the right one, you need to think about what you want to achieve with your weed killer.
For example, some are great if you’re clearing out a whole area that doesn’t have any plants in it yet. These are best known as non-selective weed killers. On the other hand, selective weed killers will kill weeds while leaving your other plants completely intact.
You must consider whether you want a contact or systemic weed killer, as one can kill weeds by making contact with virtually any part of the plant while the other will only enter through the stomata of the plant.
Lastly, you must keep your loved ones and pets in mind when choosing the best weed killer for your home. This is because some weed killers come with harmful chemicals that could affect your family’s health.
With this in mind, you can choose between chemical-based and organic weed killers which use only natural ingredients to fight the weeds in your garden. Whether you’re looking for a chemical-based or organic weed killer, we’re here to help.
This buying guide will highlight five of the best weed killers available today as well as share some information on the top features you should pay attention to when making your final purchase decision.

Features To Pay Attention To When Choosing The Best Weed Killer
Now that you know more about some of the best weed killers on the market today, it is important that you are aware of some of the top features to pay attention to when making your final decision. Here they are:
What Size Do You Need?
When it comes to size, there are two things to consider: the size of your weeds and the size of your weed killer, as in the amount you need for your garden. If you have a larger garden that is not well maintained and has many weeds, you’ll likely need more weed killer.
That being said, you’ll also need to consider the size and the type of weeds you have. The larger, sturdier, and more overgrown your weeds are, the more weed killer you’ll need to get the job done.
What Chemicals Does Your Weed Killer Use?
You should be aware of the chemicals used in your weed killer in order to ensure that you are keeping yourself, your loved ones, and your pets safe.
While research is still underway, there has now been a significant amount of evidence to suggest that some toxic substances in weed killers, specifically glyphosate, could be carcinogenic, a substance capable of causing cancer.
Other chemicals found in household products and gardening products such as weed killers are also said to be endocrine disruptors thus having a negative effect on the reproductive system, growth, and development in both children and adults.
How Safe Your Weed Killer?
In addition to the above, some stronger weed killers could be extremely dangerous if you are exposed to them for too long. Aside from affecting your skin, they could be dangerous if they were to be consumed or if they make contact with your eyes.
Read all the labels on weed killers before purchasing one in order to be fully aware of the risks associated with them.
Do You Want Organic Or Non-Organic Weed Killer?
While some would say that the best weed killers are those that use chemicals, many are now opting for organic types in order to reduce the number of harmful chemicals used in their homes.
Aside from having a less harmful effect on your loved ones, you may find that you are having a more positive impact on the environment as a whole.
The best way to choose between organic and non-organic is to do your research. We suggest you read up on the best ways to kill the specific types of weeds that are bothering you. You may find some techniques that allow you to avoid chemicals altogether.

Do You Need Rainproof Weed Killer?
If you live in a part of the world where it rains nearly all-year-round, consider opting for a weed killer that is rainproof.
Some weed killers that come in the form of granules are not affected by water whatsoever. They soak into the soil right away and just act more quickly even if they are exposed to water of any kind.
Concentrate Or Ready To Spray?
While you can buy ready made spray bottles of weed killers, the most cost-effective way to purchase your herbicide is as a concentrate.
Aside from the fact that you’ll probably save money by using less, you’ll also be able to choose your dosages based on the plants in your garden and the weeds you are trying to kill.
Tank Sprayed Or Not?
