Long before herbicides came into play, burning weeds with a flame was a popular method for handling weeds. It was not only effective, but could quickly burn away unsightly weeds. For homeowners driveways, walkways and patios, it truly was the perfect solution.

Weed torches work fast to take out weeds on hard surfaces. Although the torch can completely burn the foliage away, the heat alone destroys the plant’s cell walls. It results in the plant being unable to take in water or nutrients.

But as chemical sprays became more potent, faster and efficient at killing weeds, they became the product of choice. Sprays were easier to apply, and could cover large areas quickly. Add in that spraying didn’t require a fuel source and was extremely economical, and the weed torch quickly became a thing of the past.

The Return Of The Weed Torch

In recent years, the old flame torch has made a resurgence, and with good reason. As more gardeners and homeowners begin to worry about the health dangers of spraying, inhaling and ingesting chemical herbicides, they looking for less invasive ways to control unsightly and unwanted weeds on their hardscapes.

But with a low flame from a torch, weeds simply vanish into thin air. All without a trace weeds were ever there, or that something was used to remove them. Even better, today’s weed torches are easier to use, and even more effective.

How A Torch Works To Kill Plants

Heat is an extremely effective method for killing plant life. When high heat hits a plant, it causes the cells within the stems and foliage to rupture.

Once that occurs, the plant is no longer able to take in water or nutrients. In addition, the plant also loses it’s ability to harness the power of photosynthesis to grow and repair damage. The end result of both – the plant and it’s roots die off.

Precautions When Using A Weed Torch

Before we take a look below at selecting the best torch for weed control, there are a few precautions to keep in mind when using a torch.

First and foremost, it’s important to note that a weed torch is not ideal for every situation. Using them around extremely dry areas, or where there is a high chance for wildfires is never a good idea. Likewise, a weed torch should never be used around flammable materials, tanks, etc.

In addition, weed torches should never be used in close proximity to bedding plants, bushes and shrubs. The heat that emanates from the torch can still harm these plants, especially tender annuals.
