If you try to use vinegar that you have hanging around in your house, it will not be effective enough to get rid of those grown weeds. But, many farmers use industrial vinegar, which has a 20-30 percent acetic acid concentration. So, you could use this to kill those pesky weeds. Be very careful though.

Top 18 Safe Alternatives To Roundup

1. Brush-B-Gone vs Roundup

Brush-B-Gone is a product made by Ortho, who are very well known when it comes to herbicides. This is a very effective herbicide. Unlike Roundup, Brush-B-Gone targets certain weeds. It kills any woody plants, like poison oak, and certain vines, like poison ivy, willows, wild blueberries, and any other unwanted vines and bushy plants. It also kills any stumps of alder, maple, willow and many others. It becomes rain-proof after just two hours, which is amazing. So, it is your ideal solution for any weed problems you might encounter in your garden.


2. Burning Weeds vs Roundup

Burning weeds is a very effective method of killing any unwanted weeds. Burning weeds, or flame weeding as it is better known, is a somewhat dangerous process. You will need to get yourself a flame weeder, or a flamethrower. It usually consists of a propane tank, and a wand that is connected to it through a hose. When flame weeding, you should not aim to burn the weeds. You will need to heat them up enough so that their tissue gets destroyed. This much better than using a herbicide, because the only thing that you are doing is destroying the weeds, without harming the environment.

3. Ground Clear vs Roundup

This is another awesome product by Ortho. The Ground Clear is a great herbicide that you can use instead of Roundup. This “vegetation killer” can be applied almost anywhere you want to. From driveways, to sidewalks, to parking areas, to curbs and many more, you will be able to use this on any area that has some weed growth. With Ground Clear, you will be able to prevent any regrowth for at least 1 year, which is a huge plus in our opinion. It also acts in rapid speed, taking only one hour to start killing weeds. For the best results, it is recommended that you use it on a sunny day, when it is not too cold, because that is when weeds grow the most.


4. Vinegar vs Roundup

This is a perfect way to kill weeds without using any chemicals. We all know that vinegar tastes really bad, and most plants think the same. That is why it is an amazing method to kill weeds that are growing in your garden. The problem is that vinegar is non-selective, so if you apply it all over your lawn, it will probably get destroyed by the next day. So, you will need to be extremely careful when applying a vinegar solution. Also, you will need to buy some industrial vinegar that has high concentrations of acetic acid. Otherwise, you won’t be able to kill any of the unwanted weeds.

5. RM43 vs Roundup

RM43 offers two great options that are better than Roundup. These are the rm43 weed preventer, and the rm43 weed killer. Both of these, unfortunately, have some glyphosate. But, the concentration of it is not that high. They are both very effective in their respective functions (one prevents weeds from growing and the other kills them). If you use them together, not only will you kill any weeds overnight, but you will also prevent them from growing again for almost a year. You can use both of these anywhere you desire, whether that is your garden, patio, driveway or anywhere else.


6. Tordon vs Roundup

Tordon is recommended to be used instead of Roundup. It is not only more effective but also much safer and does not contain glyphosate. You won’t need to mix this one, as it is already working.

While these might not mean something to you, the key point to understand is that it does not contain any glyphosate, which is always a plus.

9. Natria vs Roundup

This weed killer by Natria is a great one. It works at record speed, so you won’t need to wait for too long to see results. Unfortunately, it is a non-selective herbicide. This means that if you are not careful, you might ruin your lawn, instead of just getting rid of the unwanted weeds. That is why Natria is recommended to be used in patios or sidewalks, to ensure that it does not ruin a nice garden or lawn. It kills all kinds of unwanted weeds, though, so that is a huge positive.

Preen has tons of different products. From weed preventers, to weed killers, too many other products that help you take care of your lawn, they are the ones on top.

But, it is a great selection for unwanted weeds that have grown on your patio or driveway. It is also really effective, so you should not face any issues with it, and you will probably see the results immediately.

Just add the designated amount of water, mix it up well, and you’re good to go.

Factors To Consider When Buying a Weed Killer

There are some factors that you will need to consider when you want to buy a great weed killer. These factors can often be overwhelming. That is why we have summed them up for you. Here they are:


The first thing you will need to think about when buying a weed killer is how effective it is. This will prevent any weeds from growing in the future. If you are wondering how you will be able to check how effective a weed killer is, all you need to check is the ingredients it contains.

Even though glyphosate is really effective, we would suggest that you avoid products that contain it. Try to look for more organic ingredients that are also really effective. This way, you will be able to get rid of weeds and not have the fear of poisoning yourself or others.


If you are using a weed killer for your garden, you will need to take some measures before you go out spraying or burning. After all, what is the point of having a nice garden if you can’t go out and have fun in it? All of the chemicals from weed killers, organic or not, can be harmful to your health.

This, however, does not mean that you should worry when you are done with the process. You should usually stay safe when you are spraying the weeds. If you use the methods we mentioned, you should have no problem hanging out in your weed-free lawn.

Weed Killer Size

This is a huge aspect that you need to take into consideration. Simply explained, if you have a small weed growth, you won’t need to buy a huge weed killer. So, you will have to measure the affected area, so that you do not overspend money on a new weed killer.

Thankfully, most weed killers come in a plethora of sizes. So, you should not have a problem if you want to buy a small container or a large one.

Working vs Concentrate

Most weed killers, whether they are organic or not, come in two different forms. They are either working or concentrate solutions. As you can imagine, a concentrate solution needs to be diluted with water to become active. Working solutions are usually more expensive than concentrate, so if you do not mind diluting a concentrate solution, you should buy that one.

Most products have instructions that are really understandable on how to turn a concentrate into a working product. More often than not, all you will need to do is fill the solution with a gallon of water, and you will be ready to go.

FAQs For Weed Killers
