Weed Torch Buying Guide

How Does a Weed Torch Work?

Usually either powered by gas or electricity, weed burners are portable torches that are designed to quickly produce an intense amount of heat. This heat, which is most commonly in the form of an open flame, is directed at unwanted plants to destroy the cells in their stems.

This then prevents those plants from being able to take in nutrients and water, therefore causing them to die in a matter of hours.

Do Weed Torches Actually Work?

Let’s face it – there are so many gardening products out there that promise to work miracles, but only end up being a huge waste of money.

This isn’t the case when it comes to weed torches, so long as you choose a good model.

You also need to make sure that you are using your weed burner at the correct time in a plant’s lifecycle in order to efficiently kill it off. Younger weeds that are torched in the spring and early summer will be much easier to eradicate than older and woodier weeds.

Perennials may also grow back in a couple of weeks, but all you need to do is go another round with your weed burner. Do this a few times and you will soon deplete the roots of the plants, causing them to finally die.

Let’s see how weed torch works:

The Different Types of Weed Torches

All of the weed torches out there will usually fall under one of the following 2 categories:

Lightweight Weed Torches

Lightweight weed torches are perfect for those who need to regularly spot weed along paths and driveways, and are also small enough to be used in vegetable gardens.

These torches are pretty simple to use, and that’s a big part of their appeal. Propane versions will connect directly to a gas canister and can be turned on with a spark igniter, while electric alternatives are usually plug-and-play.

When it comes to intensity, lightweight weed torches can usually produce just as much heat as a heavy duty weed burner, making them a cost-effective option for many.

Heavy-Duty Weed Torches

While usually favored by landscapers and farmers, heavy-duty weed torches are also suitable for home gardeners who have a large garden or yard to weed.

They work in a similar way to lightweight weed torches, with the difference being that instead of directly connecting to a gas canister, they are connected by a hose to a larger propane tank.

Certain models will also be fitted with regulators to ensure consistent pressure during use. This is actually quite an important feature, because it also prevents your weed burner from producing a flame that’s too large for it to handle.

Gas vs. Electric

Gas-powered weed burners tend to be more popular. Not only are they usually more powerful than electric alternatives, but they also give you more flexibility when it comes to weeding, since you won’t be restricted by a power cord.

However, electric weed burners tend to be cheaper to run, since you won’t need to keep filling a propane tank.

How Much Power Do You Need?

It doesn’t matter if a weed torch is lightweight or heavy-duty, chances are that it will produce a flame with a heat of around 2,000°F.

However, the difference lies in the volume of that flame. This is usually measured in BTU, which stands for British Thermal Units.

Very small and lightweight weed burners will usually come in at around 25,000 BTU, while the larger lightweight versions stand at about 100,000 BTU. Heavy-duty weed burners are often more powerful, with some even reaching 500,000 BTU.

Will You Need an Interchangeable Burning Tip?

Otherwise known as the “bell”, the burning tip sits at the very end of a weed burner’s rod, and this is where the flame is produced from. The larger the bell, the bigger the flame.

Most models will have a fixed burning tip, with sizes usually varying between three quarters of an inch to three inches.

However, a few of the models out there have interchangeable burning tips, meaning that you can swap the tip out for one of a different size, in order to produce a bigger or smaller flame.

You might think that a bigger flame is better when it comes to tackling weeds, but this isn’t always the case. Not only could a too-large flame damage nearby plants when weeding in your garden, but larger flames will also have a shorter burning time, since more gas is being used.

How Long is the Hose?

This only really applies to those who want to buy a heavy-duty weed burner, since the hose is what connects the burner to a gas tank.

Ideally, you want as long a hose as possible. The longer it is, the less you will have to pick the tank up whenever you want to use your weed burner in various parts of your garden.

Would You Prefer to Have an Ignition Switch?

Ignition switches are the most convenient way to turn a weed burner on – simply turn on the gas, flick the switch and out comes the flame.

However, not all weed burners have an ignition switch. Some require the use of a special starting tool in order to get the flame going, and although this is perfectly safe, it is more cumbersome than simply hitting a switch.

Extra Accessories

While some weed burners are quite basic, others come with extra accessories that can make usage much more convenient.

A few to look out for include:

  • Propane tanks – these are a must if you’re going for a gas-powered weed torch, but most models won’t come with a propane tank. However, you may be able to find a good deal if you purchase the two together from the same seller.
  • Propane tank cart – if you’re going for a heavy-duty weed burner, then a propane cart can really save you some back-breaking work. Rather than having to lug your tank and burner all around a garden, you’ll be able to easily wheel them instead.
  • Squeeze valve – these can be quite useful if your weed burner doesn’t already come with a squeeze valve. It gives you extra control over how large your produced flame is, which can also save you money when it comes to how much gas you use overall.

What’s Your Budget?

Although last on this list, your budget will likely be an important deciding factor when it comes to choosing a weed burner. However, don’t leave yourself restricted with a budget that’s too small.

You may see plenty of inexpensive weed torches out there, but make sure that the one you choose has the power and all of the features you need.

Don’t forget that your budget will also need to cover a propane tank for a gas-powered burner, which you will most likely need to purchase additionally.

Thanks to its impressive power, this weed torch burns even giant weeds quickly and immediately. More than three quarters of the weeds you deal with will instantly be decimated by this weed torch, and others can easily be fully eradicated after a second round a few days later.

What Could Be Improved?

The fact that this weed torch doesn’t have a built-in lighter can be a little frustrating, especially since pulling the turbo trigger can sometimes end up putting the flame out.

This isn’t helped by the flint striker that’s included with the product being pretty flimsy – you will likely need to find another way to light this weed burner before each use.

What We Like

This sleek silver weed burner is extremely lightweight and comfortable to use. The fact that it comes already-assembled is a huge time-saver – you can simply hit the convenient self-igniter and get burning straight away!

What Could Be Improved?

This model is powerful for a lightweight weed burner, but the flame is too small and weak for large areas of mature weeds – you would have to move extremely slowly in order to do the job effectively.


The main thing that you need to decide when looking for the best weed torch is whether you need a lightweight or a heavy-duty model.

There may not be a huge price difference between the two, but the lightweight versions are definitely more convenient to use, especially in smaller areas, so don’t automatically assume that a heavy-duty model will be superior – it all comes down to your individual needs.
