6 Natural Grass Killer for Fence Line

I’m sure your landscaping is in good shape, but how about the perimeter of your property?

The astonishing ability of grass to muscle its way into the most unexpected places can make you consider moving into a flat when you consider how to wrestle it out of that location, especially if the grass is along your fence line.

My lawn has one of the most invasive grass kinds, which was causing me problems with my neighbor because it kept crossing the wooden fence that separated our houses.

It was tough to mow that close to the fence, and I couldn’t use pesticides because my neighbor had decorative plants nearby. Fortunately, there is some effective natural grass killer for fence line.

Natural Grass Killer for Fence Line

1. Salt

Salt is utilized not just to flavor our food but has also been shown to be effective in avoiding ice buildup on our sidewalks and in many synthetic fertilizers that make our lawns seem better.

But, as life-saving and gentle as salt may sound, excessive use can have disastrous effects on plants. Ordinary table salt will damage grass along your fence line and even prevent it from growing in the future.

This non-toxic natural pesticide kills grass by drying it; in excess, it forms a ring around the roots, inhibiting oxygen and water uptake. As a result, use it with extreme caution.

Apply the slat by mixing it with hot water, making it easier for the grass on your fence line to absorb the solution quickly. A more potent mixture of 3 parts of salt to one part of water will be effective.

If you have any ornamental plants nearby, it would be best to use a spray bottle to apply the solution. Don’t worry if your grass is tolerant to salt; the following method will work.

2. Mulch

Placing mulch along your fence line is a good idea.


The mulch will smother the grass, killing it by cutting off sunlight and air while providing a physical growth barrier. Mulching can be done with various materials; newspapers, cardboard, and even an old shower curtain do the trick. Your patience is the only price you have to pay if you choose this method.

Mulching takes longer to kill grass; it can take up to 2 to 3 months for the mulching to completely get rid of the grass. Additionally, some species of grass may put up a fight depending on the type of mulch you will use.

My yard is Zoysia grass, a very invasive fearsome foe. If you pick a fight with it, you must be prepared, so I too got tough, I used cardboard, and the results were impressive. Otherwise, if you prefer using a newspaper, spread a layer of about 6 inches and lightly spray it with water to prevent it from blowing away.

3. Vinegar

Spraying vinegar will make the grass along your fence line fade away, but the typical household vinegar will not be effective enough not unless reapplied a couple of times. Instead, use concentrated agricultural vinegar to get a better result.

Vinegar is effective at killing young grass; it burns the blades but does not affect roots. For mature grass, you will have to reapply the vinegar. Apply the vinegar when the weather is warm and there is no rain forecast.

Remember that the active ingredient, acetic acid, even at a concentration below 11 percent, can cause skin and eye irritation, so it is crucial to wear protective gear.

4. Baking soda

Baking soda may be the inexpensive ingredient that will do the trick for you. It contains bicarbonate, a salt that causes the same effects as the common table salt on grass.

There are many ways to apply baking soda on grass; dumping a modest amount of this ingredient along the fence line is the simplest.

Another effective method is to combine baking soda with vinegar. Place the mixture in a spray bottle, put on garden gloves, and apply your mixture. The solution works best during summer and when reapplied after every week.

5. Boiling water

If you are new to using boiling water to kill plants, I understand if you are wondering if boiling water will work. The method works perfectly. It scalds the plants’ cells, but it will take a second application to kill the grass completely.

If you are to cover a larger area, you will need a larger pot to carry enough water. To effectively kill the grass along the fence line, you will have to clip the grass short and then quickly pour the boiled water before it cools.

Remember to wear long pants, sleeves, and closed shoes to protect you from burns in case the water spills.

6. Rubbing alcohol

Rubbing alcohol is a great earth-friendly way to kill grass along your fence line. But be careful when using it since when in excess, it will negatively impact your soil if you are planning on planting anything along the fence line.

Rubbing alcohol when applied to the grass along this area, the grass will lose water, the leaves will wilt, and the grass will eventually die due to lack of photosynthesis. Mix the rubbing alcohol with liquid dish soap and water.

Place the mixture in a spray bottle and spray it along your fence line. Repeat spraying in case it rains.

It is very annoying when you are done controlling pesky weeds in your garden, and now it’s time to put your feet up and take in the scenery; you start noticing grass invading your fence line.

I understand you are sick and tired of the never-ending garden chores, and it can be tempting to head straight to the store for a bottle of herbicide, but before you do that, consider your lovey neighbors. Instead, use the above simple natural grass killer for fence lines.

Before you rush to the store to get harsh chemicals to kill weeds on your fence line, check your kitchen cabinet; you won’t miss something practical to kill grass in that tight space.
