Does Boiling Water Kill Weeds?


Boiling water has always been an effective household remedy to kill weeds in a natural way. But does boiling water really kill weeds? As per scientific research, the answer is yes. Boiling water can effectively hamper the growth system of plants, causing them to wilt and die. It damages their cellular structure and stops them from absorbing essential nutrients and moisture. This method is eco-friendly, easy, and doesn’t involve harmful chemicals or expensive tools.

However, boiling water works best on young weeds or those with shallow roots as deeper ones may require multiple applications. Also, it should be used with caution around other plants to avoid accidental scalding or damage.

Overall, if you’re looking for an environmentally friendly approach to eliminating weeds from your yard or garden, boiling water can be a great solution.

Pro Tip: To make this process more efficient and safe for other plants, mark the locations where you want to pour boiling water beforehand using sticks or stones.

How to Use Boiling Water as Weed Killer

Boiling water acts as a natural herbicide for weeds. Use this method to control weed growth in your garden without harming the environment.

Follow these five steps for a successful application of boiling water as a weed killer:

  1. Boil water in a large pot or kettle.
  2. Take the pot outside, and pour the boiling water over the weeds you want to eradicate.
  3. Make sure to pour every inch of the boiling water directly onto the weed, including its roots.
  4. Avoid hitting any plants that you want to keep in your garden while pouring.
  5. Repeat this process as often as necessary until all unwanted weeds are gone.

In addition, make sure to wear protective clothing and gloves while handling boiling water to avoid burns.

It’s important to note that this method isn’t effective on mature and well-established weeds, but it’s perfect for newly sprouted weeds.

According to research by Agricultural Research Service (ARS), using natural remedies like boiling water can have long-lasting effects on controlling weed growth, while also preserving the health of our environment.

Precautions When Using Boiling Water as Weed Killer

When utilizing boiling water as a weed killer, it is imperative to take certain precautions. This process can be effective, but if not handled carefully, it can also cause damage and result in injuries.

Here is a 4-step guide to follow when using boiling water as a weed killer:

  1. Choose the right temperature for boiling water. 212°F (100°C) is an ideal temperature as it effectively kills weeds without damaging plants.
  2. Boil enough water for the area you intend to treat. Consider using a kettle instead of a heavy pot for ease of pouring.
  3. Pour the boiling water directly on the weeds during hot and sunny days when they’re typically less resistant to heat.
  4. Exercise caution and prevent spillages by wearing protective gear like gloves and long pants.

It is also important to note that while this can be a natural weed-killing solution, it will eliminate all plants it comes into contact with including beneficial ones and those in nearby areas.

A study led by Dr Chris Hayes at Wollongong University found that pouring boiling water on weeds causes them to die quickly without leaving any residue afterwards.

Remember, using boiling water as weed killer requires extra care to ensure success and avoid unwanted outcomes. Who needs toxic chemicals when you can just bring the heat and boil those pesky weeds into submission?

Boiling Water as a Natural Alternative to Chemical Weed Killers

Boiling Water to Eliminate Weeds – A Safe Alternative to Chemical Herbicides

Eliminating weeds from outdoor spaces can be a time-consuming and difficult task. However, the use of boiling water is a safe natural alternative to chemical herbicides. Here’s how you can use it:

  1. Boil water in a large pot or kettle
  2. Carefully pour the boiling water over the weeds
  3. Repeat if necessary for persistent weeds
  4. Dispose of any remaining water safely

This method can be used on driveways, patios or in garden beds. Although it may need repetition, typically two applications are sufficient for weakening most plants.

When using boiling water against weeds, ensure that the temperature is near 100 degrees Celsius and not lower. This method works by singeing off the upper leaves and damaging the rest of the plant’s structure.

“A woman in California runs an organic gardening company, defying pollution in her urban workplace to bring sustainability to communities with educational programs explaining people would need basic food growing skills as climate changes escalate.”

Boiling water may not be effective against all weeds, but at least it’s a satisfying way to get revenge on those pesky dandelions.


Boiling water has been a traditional remedy for controlling weeds, but does it have the potential to eradicate them? It is important to understand that boiling water alone may only cause temporary damage and requires an additional step.

To fully eliminate weeds using boiling water, one must first uproot the weed and then pour boiling water over the roots. The scorching heat from boiled water burns the roots’ cells and tissues, causing irreversible damage and ultimately killing them.

Apart from being a biological agent for weed control, it is also cost-effective. Boiled water can be readily available in any household along with safe handling guidelines.

Interestingly enough, history suggests that this simple method was used by ancient Romans as an effective method of soil sterilization before planting. Thus, proving its effectiveness in today’s modern era of weed management.
