Bleach is extremely corrosive and shouldn’t be used in places where you want vegetation to grow in the future. Its pH level is extremely high, and it effectively kills anything green. Sometimes, grass grows in places we don’t want it to grow, and we just want to kill every potential of it. With these facts in mind, does bleach really kill grass?
Bleach raises the pH level of the soil, and vegetation and grass do not thrive in soil with high pH levels. When bleach is introduced to healthy soil with grass, it instantly dies. It takes only three days for the grass to turn brown and completely die when sprayed with bleach.
Bleach is so radical it should never be used for killing unwanted weeds and grass, especially in fertile soil where you are likely to grow crops in the future. Once it is introduced, it becomes so hard to neutralize its presence in the soil. You would be required to flush the soil for it to become fertile again.
If you are quickly looking to kill the grass and retain the health of your soil, you should carefully apply bleach to the grass without contaminating the soil. There are many ways to kill grass with bleach. Keep scrolling to learn all about this combination.
How Long Does It Take for Bleach to Kill Grass?
Bleach seems to work as fast as wildfire. It takes up to four days upon application for it to kill grass. Bleach works by altering the pH balance of the soil. This, in turn, kills all the nutrients responsible for the health of the grass. The grass will go on a starving mode and, within days, will be void of color and life.
How to Apply Bleach on Grass
If you apply bleach with care and moderation, you might have another chance with the soil for regrowing vegetation. But, it all narrows down to why you are using bleach rather than other weed and grass killers to eliminate the grass. Here are simple yet effective ways to apply bleach to rid yourself of the grass.
- Put bleach in a spray bottle to easily pump it out. Spray bottles give you control and excellent coverage, but also boil down to the surface area. You may also try using a hair dye applicator. Its narrow tip provides excellent performance, especially if you are being careful not to contaminate the soil. Avoid using bottles and applicators that can intermittently spew spray in unwanted places.
- Spray your grass portion by portion to avoid spewing on needed plants and contaminating the soil. Bleach is extremely aggressive and can kill any plant that stands in its way.
- After three to four days, you will notice that the grass will start to turn brown and appear withered and dead. Carefully pull out each dead grass and put them away from the soil. The residual bleach should hinder any further growth unless the soil is flushed.

Will Grass Grow Back After Bleach?
It all depends on the kind of bleach you use. However, chlorine bleach is the most corrosive of them all. It would completely kill your grass and make it difficult for it to regrow as the aim of bleach is to alter the pH balance of your soil.
Both the salt and increased pH level in your soil will make it difficult for grass to thrive in it. The broken salt in the bleach will kill all the nutrients in the soil and starve the grass. Within no time, the grass will start losing health, begin to wither, and turn into a dull color before completely dying.
Once the pH level of the soil is high, it will be very difficult for any vegetation to thrive in it. Normally, the pH of good fertile soil should be between 5 and 7. Anything below or beyond that cannot allow grass to grow.
Will Diluted Bleach Kill Grass?
When bleach is diluted with water, it might not be as effective as the concentrated solution. Adding water only means that you are subduing the volatile solution, thus decreasing the effectiveness. Diluted bleach cannot be so detrimental to kill the grass. It will burn your garden unevenly and leave some ugly brown and green patterns on your lawn.
What Bleach Kills Grass Instantly?

However, if for some reason you need to use diluted bleach spray, always buy ready-to-use brands. You will find many options in stores. You also need to read the labels on your bleach bottles and know the best ways to use them.
Conclusion
Always be mindful of your environment when using bleach spray on grass, especially if it is for your home garden or lawn where pets and children play. You only want to kill grass and nothing else. If bleach comes in contact with unintended grass, wash it thoroughly with lots of water to flush it off.
