Do Blue Tarps Kill Weeds And Grass?
A blue tarp works by using a process called solarizing. The tarp traps heat and moisture underneath while blocking the sun from reaching the weeds and grass. The weed seeds will quickly germinate due to the trapped excessive heat. This process will kill the weeds and the newly germinated weed seeds.
If the weed types are especially persistent, you may need more time to kill them. You can lay out the blue tarp for three weeks or more to eliminate the weeds during the growing season.

Different Kinds of Tarps
Tarps are useful in agriculture because of their universal usage. Tarps are breathable and effective to use as curtains or covers.
Aside from using blue tarps to kill weeds and plants, you can also use them as a cover for your plants to keep them away from too much exposure to sunlight. Blue tarps are made of polyethylene and are sturdier than standard tarps. A blue tarp is UV-resistant, waterproof, tear-resistant, and stretch-resistant. Blue tarps vary in size, thickness, and weight.
Blue tarp is the most popular color among tarps. Its use is for outdoor protection and is known as the sturdiest color of tarp. Other tarp colors are silver, clear, white, black, red, and camo.
Blue tarps are an all-purpose material in agriculture, camping, and industry. As we mentioned, the blue tarp can be used in prepping soil beds and killing unwanted grass and weeds.
Black tarps are perfect for trapping heat. It can be used to heat the pool or a cover on a pool heater during the winter season. Using a black tarp helps trap heat and light, which can cook the soil and control weeds and grass.
Clear tarps are used in outdoor spaces to trap or protect while allowing full sun exposure. Most gardeners and farmers use a clear tarp in prepping. Some farmers use clear tarps instead of blue tarps to kill weeds and grass. Gardeners also use clear tarps ins greenhouses and balcony gardens.
Silver tarps are best for the reflection of light, and like white tarps, can be used as a cover and extra protection from direct sun.
Red tarps have the same function as orange tarps. This tarp is commonly used to cover holes.
Can You Use Blue Tarp To Cover And Protect Your Plants?
A blue tarp is helpful for your plants during winter by blocking frost and trapping heat inside the tarp. It is a cost-effective solution to protect your plants.
- Trap the warmth from the sun and set up the tarp before sundown and before the cold night comes.
- Prevent the tarp from touching the plants because its weight might damage them.
- Secure the tarp edges to ensure no cold wind could enter and expose your plants. You can place rocks or stones to put some weight on the edges.
What Are Other Ways To Kill Weeds?
Aside from using blue tarps to kill weeds and unwanted grass, these are other methods you can use:
You may need a lot of salt if you have a huge garden full of weeds. Grab a discounted bag of salt from any store. Mix it with water and use a spray bottle to apply the mixture. Spray all over the garden bed where you want to kill weeds and grass. Avoid spraying on plants you don't want to harm.
Vinegar is a natural weed killer. You can pick vinegar with 20% acidity for a faster effect. Spray the vinegar directly on the soil with the weeds you want to kill. Be careful in spraying because vinegar can kill any green plants.
Surround your garden bed with lawn edgings or mulching to keep the weeds away from your plants.
The cheapest way to kill your weeds is to grab your old newspapers and cover the weeds in your lawn. Newspapers block the sun and reduce airflow, and will control the growth of weeds and kill them. Place heavy things on top of the newspapers to hold them in place.
Pouring boiling water is another way to kill weeds. Although, you need to be careful handling boiling water as this is dangerous to your skin and on other plants. The weeds will quickly wilt and have their roots killed in the next few days.
Borax is toxic to any plants, so it is advisable to be careful of using this because you may harm other plants around the weeds. Sprinkle only on areas without other plants around.
You can kill weeds and grass using bleach. Put the liquid bleach in a spray bottle and spray directly over the weeds. Do the process within 2 to 3 days to destroy weeds and grass.
If you have excess vodka at home and want to kill some weeds around your garden beds, you can use it as a weed killer. It might be costly, but this is also effective. You can also mix vodka with dishwashing soap and two cups of water.
Place the mixture in a bottle, then apply it to weeds. It is best to spray the vodka mixture in the daytime as the sunlight intensifies the effect of vodka on the weeds.
Mowing weeds and grass is the most effective way of removing them. It could be a lot of work, especially if there are too many weeds you need to cut.
Cutting the head and body of the weeds doesn't kill the roots and seeds beneath the soil. Weeds and grass will surely regrow. You will have to mow the weeds every time they grow back.
Using commercial herbicides can make your job easier in getting rid of weeds. However, you need to be careful in handling and spraying. Make sure that you won't spray over other nearby plants.
Read the label and follow the instructions on how to apply herbicides to plants. Also, there are types of herbicides that you can use for specific plants. Some herbicides are harmful to humans.
