What is the Cheapest Way to Kill Grass?

Lawns offer many benefits. They can prevent soil erosion, improve the soil structure, and add value to your property. At times, the lawn might look hopeless. It can be plagued by weeds, have patchy spots, or turn brown.

This can result from high temperatures, diseases, or issues with the soil PH. You may decide to overseed or start from scratch. Replacing the lawn with new grass is a good idea since you will get rid of the stubborn weeds in your yard. Also, you will be able to improve soil compaction issues and correct the drainage system problems.

Removing the old lawn is not easy. You might find yourself spending a lot of money in the process. In this case, you need to look for the cheapest way to kill grass. And you can achieve this by denying the grass light for an extended period. But this method requires patience as it may take up to six months to complete.

Here is the Cheapest Way to Kill Grass

1. Use a black plastic

Killing grass with plastic sheeting is more effective in the summer months. This method uses high temperatures to cause serious stress to the grass. When the temperatures are above 95°, grass experiences heat stress and dies.

Black plastic is a good option because it blocks light from reaching the lawn, making the grass lose its color and die.

2. Consider newspapers

The use of newspapers is another cheap method of killing grass. This method requires a large collection of newspapers to block all the light. And because the wind can blow the newspapers, it is good to apply mulch as a final step.

Spread a layer of mulch about 6 inches to press the newspapers against the grass. Also, spray water over the area to make the grass rot faster.

3. Cardboard

Cardboards are thick. Thus, they will completely block sunlight from reaching the grass. Besides, the cardboard will biodegrade over time, therefore, feeding the soil underneath with organic matter, which helps to boost the nutrient content.

To make this method effective, you’ll need to overlap the edges of the cardboard to prevent grass from penetrating through the gaps. Also, place stones and sticks on the cardboard to pin it in place. Remember to spray water on the cardboard to help in the decomposition process.

Can you kill grass with vinegar?

Vinegar can be your option if you are looking for an inexpensive way to kill grass. However, it is a non-selective weed killer.

Here are 3 ways to kill grass without harming the soil

Organic option

Vinegar is an effective weed killer that does not leave residues in the soil. It is found to be an effective option for killing grass down to the root. You can find this solution in garden stores, but it is good to be careful during the application since it can burn your skin at high concentrations. 

Covering the area

Although methods such as using black plastic and cardboard take time to kill the grass, they destroy the weed to the root. Also, they can improve the soil quality since some materials such as cardboard degrade over time. 

Herbicides

Some chemical herbicides kill the grass without remaining in the soil. For instance, glyphosate enters the grass through the blades and travels to the root system, killing the entire plant without leaving harmful residues in the ground. 

Does your grass creep in areas where it is not intended to be? Or do you want to replace your lawn with a low-maintenance landscaping option? Does your lawn look unattractive, and wish to start a new one? The first thing you need to think of is the cheapest way to kill grass.

Before starting a new project, you need to eliminate the old grass. The best method of killing grass will depend on the time available and your budget. For instance, covering the grass with black plastic is not attractive and may take several weeks or months before you remove the dead grass.

In this case, you can use vinegar. But in a situation where vinegar is expensive, you can consider covering the grass with newspapers, cardboards, or black plastic. Besides, if you want to kill grass quickly, you can choose herbicide that will match your yard’s needs.

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care.
