Use This Simple Method To Remove Unwanted Grass From Your Yard

Laundry detergent can have many uses for cleaning clothes and tackling messes in the home. But did you know that it can also be used to kill unwanted grass in your lawn? 

While this approach is not necessarily recommended and should be done with caution, there are times when it can be helpful. 

For example, if you want to eliminate patches of grass to switch over to something different, like gravel or mulch, then laundry detergent might be just the thing you need.

Will Laundry Detergent Kill Grass

Certain circumstances are necessary for grass to grow; seemingly mild cases can be fatal. While laundry detergent is harmless for your clothing, it might ruin your well-manicured grass. Don’t let detergent destroy your grass, whether you unintentionally drop some or use it as an insecticide.

Grass Protection

Although soaps do not inherently hurt the grass, certain compounds in laundry detergent especially injure grass but do not necessarily kill it. Laundry detergent should be thoroughly diluted with water before being used in an insecticidal spray.

A maximum 3 percent dilution of laundry detergent, or slightly less than two tablespoons of detergent for every quart of water, is advised by the University of Rhode Island.


The American Rhododendron Society claims that water is a powerful pesticide that doesn’t have the adverse effects of washing detergent. Water-stressed plants are frequently more vulnerable to insect pests, although spider mites and aphids may be controlled with routine watering. Before using additional strategies, water your yard.

Keeping Damage at Bay

The harmful effects of laundry detergent can also be stopped by water. Like water-soaked grass dissolves dangerous salts, laundry detergent is diluted and spread across the region. If you believe you spilt half a cup of detergent, soak the grass in 1 gallon of water. This results in a detergent dilution that is safe for grass at 3%.

Natural Grass Killing

Use salt in place of laundry detergent to kill the grass. Salt, unlike laundry detergent, is sure to kill grass rather than harm it. Salt should be spread over the undesired grass to dry and nutrient-deplete it. A clue that the salt is working is when the soil turns white.

Does Laundry Detergent Affect Plant Growth?

The impact of detergent on plant development is a hotly contested topic. Some people claim that laundry detergent, with its high levels of chemicals and salts, can be toxic to plants and stunt their growth. 

Others argue that when used in moderation and carefully mixed into soil, detergent can help to promote a healthy plant environment.

At the heart of this debate are questions about the role of salinity and pH in supporting healthy plant growth. While most agree that high salt content in the soil prevents plants from absorbing nutrients effectively, there is less agreement about how pH level impacts plant health. 

According to research, some detergent chemical components can assist buffer optimum pH levels and encourage excellent nutrient absorption.

Despite these mixed findings, the bottom line is that excessive laundry detergent will almost certainly damage your plants by altering soil quality and nutrient composition. 

This is crucial to exercise caution while selecting a specific detergent brand or composition.

Always consult a knowledgeable gardener or horticulturalist before applying it directly to your plants. Ultimately, as with so many things in life, moderation is essential when using laundry detergent around your garden.

Do Plants Benefit From Laundry Detergent?

Regarding whether or not laundry detergent is safe for plants, there has been significant discussion in recent years. Some experts argue that the chemicals in laundry detergent are too harsh for delicate plant life and can lead to poor growth or even death of the plant.

Others argue that, when used correctly, laundry detergent can be beneficial for certain types of plants by providing them with essential nutrients and minerals.

There doesn’t appear to be a definite agreement yet on whether or not laundry detergent is safe for plants. Some people believe it is safe to use a small amount of laundry gel as a diluted fertilizer, while others are wary of any chemical input into the soil. 

Ultimately, it may be up to individual gardeners to decide whether or not they feel comfortable using laundry detergent in their gardens and what type of plants they should use it on. 

However, one thing is sure: when used carefully, even something as seemingly mundane as laundry detergent can play an essential role in tending a beautiful and productive garden.

Which Detergent Is Secure For Plants To Use?

Different factors can affect how a detergent damages or benefits plants, such as the concentration of the detergent and its pH level. Research suggests that most standard mainstream brands contain harsh chemicals that can damage delicate plant roots.
