Plants are great! As long as they don’t run rampant. But no paving stone owner is spared from weeds. Can you count on one hand how many times you’ve been annoyed by them, or do you need two hands to do it?

But now you can breathe a sigh of relief, because there is a solution. With a weed burner you can kill the weeds, at least for a while. To help you find the right tool for you as quickly as possible, we have done the research work for you. We have summarised here how the different products compare and what you should know before buying.


  • The weed burner is a weed-killing device that is operated either with electricity or gas. It consists of a handle and a burner tube with a flame coming out of the end.
  • If you choose an electric burner, you should pay attention to the cable length of the product when buying it. You may also need an extension cord. You will need to buy gas cartridges for the gas burner regularly.
  • The burner can only damage the weeds, not remove them completely. You will still have to pull them out by hand. However, it will take longer to grow back than if it is just plucked.

The Best Weed Burner: Our Picks

We have compared the market players in weed burners so you don’t have to. Below you’ll find an overview of our favourites, which we hope will make your buying decision easier.

Buying and evaluation criteria for weed burners

Finding the perfect weed burner for your individual needs is not that easy. To make it clear what you should look for when buying a weed burner, we have summarised some buying criteria for this device.

To ensure that your weed burner meets your requirements, you should pay attention to the following when buying it:

We would now like to explain these four points to you in more detail so that you can finally buy the right weed burner. After all, you don’t want to make a wrong decision or come across unpleasant surprises.

Operating mode

Weed burners are available in two different versions: either gas or electric. While electric burners are connected to a power cable, gas burners have a gas cylinder attached to the handle of the device. This gas cartridge usually contains a mixture of butane and propane gas.

Length of burner tube

The length of a weed burner is something to pay special attention to when buying one. After all, the aim is to avoid backache. The weed burner usually has a length between 80 cm and 100 cm, so there should be a suitable device for every body size.

Note that sellers often list the length of the burner tube (or the weed burner) as “height” on their websites. So don’t let this confuse you. To get a better idea, you can also use a metre rule. Then you will know exactly what to expect.


The weight of a weed burner also depends on the mode of operation. It is noticeable that electric burners are often lighter than gas burners. However, the differences are very small. In the case of a gas-powered device, the gas cartridge in particular determines the weight. These usually contain 600 ml of liquid.

For large-scale use, large gas cylinders weighing several kilograms are used. For this purpose, there are either mobile cylinder trolleys or straps to strap on so that the gas cylinder can be carried like a rucksack.

Flame temperature

The flame temperature is stated by most manufacturers and ranges from 600 °C to 1,800 °C. These are extremely high temperatures which can cause a fire. These are extremely high temperatures, which pose a great risk of injury. Therefore, never carry out weeding barefoot.

For weed control, however, it is seemingly unimportant how hot the tool can get. The varying temperature only determines how long the burner has to be held over the plants to be removed. More power = less time spent.

Guide: Frequently asked Questions about Weed Burners answered in Detail

When looking for a suitable weed burner, questions always come up. With this guide, we want to anticipate them so that the decision is easier in the end.

How does a weed burner work?

You must not think of flaming with a weed burner as simply burning the weeds and thus making them disappear completely. The shock-like heating of the plant merely causes the protein it contains to coagulate. After two to four days, the withered remains can finally be pulled out of the ground quite easily.

The question of whether the burner saves you from having to bend down must therefore unfortunately be answered with “no”. Nevertheless, the torch makes the work easier, as the weeds can be removed much more easily after heating.

Another positive aspect is that weed burners are very environmentally friendly. They are poison-free and therefore absolutely legal and harmless. But remember: you will never get rid of weeds “forever”. After some time they will sprout again and you will have to repeat the process.

What is a weed burner good for?

Although it is called a “weed burner”, this device has other talents as well. However, not every model is suitable for all these possibilities. When buying, pay attention to what the manufacturer promises. These are possible areas of application:

  • Paving stones: Probably the most common use. Mostly used on the home’s front lawn.
  • Beds: Unwanted weeds can also be flamed in the bed. But be careful of the remaining plants and make sure you don’t catch any useful animals – such as worms and beetles.
  • Barbecue lighter: No lighter at hand? Your weed killer will do the trick. However, extreme caution is advised!
  • De-icing: Yes, the weed burner can also be used in winter. If you need to clear your pavement of ice as quickly as possible, you can simply use the burner.

What a weed burner can do! Hopefully, the rest of this article will help you find out whether it’s worth it for you. Be aware of what you intend to do with your weed burner so that you are not disappointed later.

How do I use a weed burner?

The handling of weed burners is slightly different for each device, but basically similar and uncomplicated for all of them. There are differences between gas and electric burners.

With gas burners, the gas cartridge is screwed onto the handle or the gas bottle is connected to the device via the hose. The valve is then turned open slightly so that the gas flows and can be ignited at the touch of a button using the “piezo ignition”. Older models of the burner may still have to be lit by hand, which increases the risk of injury.

Electric burners have a cable that plugs into the socket. You may need an extension cord for this. When buying a burner, check the length of the cable. The button on an electronic burner usually has to be held down permanently, which can be tiring in the long run.

How much does a weed burner cost?

The price difference between gas and electric burners lies in the fact that gas burners require regular replacement of gas cartridges, whereas electric burners do not. These prices are to be expected at the time of purchase:

Price range Available products
Low-priced (15 – 30 €) only gas-powered, less comfortable handle
Medium-priced (30 – 45 €) electric units also available, better handle, more choice
High-priced (from 45 €) suitable for professional work, mostly as trolley with wheels

Before you decide on a price range, you need to know what you need your tool for. For a small paving stone path? Low-priced is perfectly OK. For the entire house driveway? A mid-priced machine is absolutely worth it for that.


The weed burner is in any case an effective method of tackling weeds. It is easy to handle and allows relaxed weed treatment while standing.

However, you must be aware that the weeds cannot simply be burned, but must still be removed by hand. However, because the plant is already weakened by the heat, it is much easier to pull out of the ground than before the heat treatment.

But is a weed burner worthwhile at all? Well, it is – apart from normal weeding – the only permitted method of killing weeds in Germany. The law prohibits the use of toxic plant killers for this application, which leaves only the flaming device.
