Does bleach kill grass might be something you wonder about often. Bleach is a common household staple, and its many benefits are not just confined to cleaning and disinfecting items.
Before using bleach in lawn care, you need to learn how bleach works, what precautions you need to take, and what alternative homemade weed killers you can use instead of it. Read this article to find out about all these things and much more coming up ahead.
Does Bleach Kill Grass?
Yes, bleach kills grass, especially with a chlorine concentration above 150 parts per million. It makes the pH of the soil rise so high that all vegetation dies. Bleach is often used when you want to kill grass permanently because it alters the soil’s chemistry.
– How Does Bleach Get Rid Of Grass?
Sodium hypochlorite is the ingredient in bleach responsible for its weed and grass-killing effects. This is the form by which chlorine affects grass and soil. Look at the bottle to see how much chlorine or sodium hypochlorite bleach contains. You will find that it will be more than seven percent in most household bleaches.
When bleach is applied to the grass, a couple of things happen. The soil absorbs the chlorine part of sodium hypochlorite into the roots. From the roots, it enters the rest of the grass blades and produces chemical burns to it.
Bleach breaks down when present in the soil and combined with water. This raises the salt levels in the soil to unbearable levels. Salts kill all beneficial microbes in the soil and prevent the roots from absorbing any water. Your grass will become dehydrated, dry, and brittle on the touch.
– How To Use Bleach To End Weeds and Grass
We would never recommend using bleach to kill weeds or grass on the lawn or turf. However, bleach can be an effective permanent grass and weed killer in areas where you don’t want any grass growing. If the grass seems to be invading the cracks in the side or driveways, then bleach will help you remove it permanently.
Take your protection first because even household bleach can be a bit corrosive. Wear thick waterproof rubber gloves over your hands and clothes that don’t leave skin uncovered. We recommend wearing goggles and a hat and tying your hair back.
Diluted bleach is not going to be much effective. Measure an appropriate quantity of undiluted bleach over the grass you want to kill. Approximately just one glass of bleach will be needed to kill grass in an area of six by six square inches. Make that two cups of chlorine bleach if the grass is too compact and made mostly of clay.
Wait for one to two days, and you will see how the bleach kills weeds permanently . You will still have to uproot the yellowing weeds and grass by hand after they have died.
– Precautions While Using Bleach
Bleach available for household use these days are not as corrosive as it used to be in the past. Still, it would be best if you took all the necessary precautions for your safety and the safety of those around you.
First, choose the day you will carry out this weed control operation carefully. Defer it to another time if the day is particularly windy.
Otherwise, the bleach might blow into someone’s eyes, nose, or parts of your lawn where you don’t want grass or plants to die.
Keep an ear out for potential rainfall within the next few days. You don’t want the rainwater to wash off and drain the bleach all over the lawn or into nearby bodies of water. Lastly, as mentioned above, protect yourself well before using a bleach weed killer.
– Accidental Bleach Spilled In The Lawn: What To Do
If you spill bleach on grass by accident, quickly flush the exposed area using a copious amount of water. Use as much water as possible to soak as deeply as possible.
Some grass blades and other plants will immediately die or be damaged by the bleach. Luckily, you can save your soil from getting contaminated and the rest of the vegetation from dying.
– Better Alternatives To Using Bleach
You can use several other options that are way safer than bleach to eliminate grass and weeds growing in the lawn or driveway. We strongly recommend you go straight for commercial herbicides instead of any homemade approach.
For the broadleaf type of weeds and grasses such as St Augustine, a 2,4 D herbicide works the most quickly. It will also kill other plants in the garden, so be careful when using it.
Mix this herbicide in water as per the instructions given by the manufacturer and spray it wherever you want. Spraying early in the spring will be the most effective when invasive grass is just beginning to sprout.
A glyphosate herbicide kills weeds better for narrow-bladed grass and weeds. Glyphosate only starts working when the soil temperature exceeds 60 degrees Fahrenheit. For both warm and cool-season types of grass, spring and summer are the right time to spray a glyphosate herbicide.
– Will Bleach Kill Lawn Fungus?
Yes, bleach can kill lawn fungus if applied consistently for several weeks. Dilute bleach with water to make a solution that is 50 percent bleach and 50 percent water. Pour it on the lawn for 20 minutes before washing it with water. You don’t want the bleach to seep into the soil and collect there.
– Does Clorox Bleach Hurt Grass?
Yes, Clorox will hurt grass and cause it to burn. It is one of the most common bleaches sold across the US and can be used to kill grass, weeds, and other plants. It is better used as a spot treatment to hurt grass in one spot.
You sure went through this article in record time. Therefore, we would like to conclude with the following points.
- Burning and dehydrating the sodium hypochlorite in bleach can kill grass permanently.
- You can use bleach to remove grass growing between the cracks in pavements and driveways, but we don’t recommend using it on the soil or the turf.
- If bleach accidentally falls on the grass, leave everything and water the affected area deeply.
This guide was about whether bleach can effectively be an herbicide against invasive grass. You learned when and where it can serve as an effective grass killer and how best to use it.
