Will Bleach Kill Weeds and Grass? Here’s How to Use it

If you are reading this, you might have heard that there is another way to kill the weeds in your yard instead of using a special herbicide.

Bleach is a chemical that kills weeds and grass. It does not kill only the green parts of your lawn, but it will also kill the roots if you apply enough bleach to them.

If you have an area in your yard where you want to remove all vegetation, then applying bleach can be quite effective for killing all weeds and grasses in one fell swoop.

In this article, you will learn what is the right way to apply bleach and what to keep in mind before and during your attempt to get rid of the weeds that bother you.

How to Kill Weeds With Bleach

Before you start

First of all, you should take some precautions:

  • choose a day without wind for the procedure
  • don’t mix the bleach with other chemicals
  • avoid applying too much bleach on the soil of your garden
  • wear safety goggles
  • wear safety gloves
  • wear breathing mask

Note: If you’ve accidentally put too much bleach on an area you want to use, here is what you need to do:

  • flush the soil with a lot of water for the next few months
  • use soil pH tester to keep track of the pH and if it has stabilized

Step 1

I buy bleach all the time to clean my house. I make sure that it’s full-concentrate so there aren’t any more harsh chemicals than are necessary for cleaning around here!

If you don’t have full-concentrate bleach at home, just buy one.

Step 2

Get an empty and clean spray bottle

Step 3

Fill the spray bottle with undiluted bleach. Pour it in through a funnel to avoid getting it on your skin. Bleach can irritate and burn the skin of your hands.

Step 4

Place the top on the bottle and set the spray to “mist.”

Step 5

Point the spray bottle to the weeds you want to get rid of and mist their green part.

Step 6

Switch the sprayer bottle to “spray” and point the bottle’s nozzle to the roots of the weed. Then spray carefully and do your best to avoid your favorite plants or your neighbor’s grass.

Step 7

Give the bleach time to work. It usually takes 2 to 4 days.

Step 8

When the bleach has done its job you can easily pull out the weeds.

Is Using Bleach to Kill Weeds Safe?

Bleach is a dangerous and strong chemical, so it’s not a surprise that it’s not completely safe to use it.

It is even forbidden to be applied as a herbicide in some areas. If you intend to use it, it will be a good idea to check specifically for the area you live in.

If you Decide to Use Bleach to Kill Weeds, it’s Important to:

  • avoid using too much bleach
  • keep pets and kids away from the bleached area at least until it’s dry
  • don’t use it near your favorite plants
  • don’t use it near edible crops
  • avoid using in near sources of water
  • choose a day that isn’t windy or rainy
  • don’t mix bleach with other chemicals

Alternatives of Using Bleach to Kill Weeds

  • Weeding out the weeds.
  • Using a high-pressure water hose to spray down the area with water, using a brush or broom to clean off any remaining plants.
  • Cover weed patches in black plastic and wait for hot summer days when it reaches 160 degrees Fahrenheit underneath the surface of the ground.
  • Applying herbicide as directed by manufacturer’s instruction sheets on packaging(strictly following all guidelines). You can also use other products that will kill existing weeds and fertilize your lawn while giving you some time before new ones grow back – usually between two weeks up to four months depending on how often you apply it.

In Conclusion

Bleach is one viable option for killing weeds. Bleaching can help with small patches of unwanted plants, but it’s not the safest solution to weed problems. The best way to ensure that your lawn stays free from new weeds in the future is by mowing on an appropriate height setting and working hard at keeping your grass healthy and dense with waterings during dry periods of weather.
