How Long to Wait to Mow After Lawn Treatment

What Is Lawn Treatment?

These are various procedures and techniques that can be applied to your lawn to improve and maintain its health and appearance.

You may need a lawn treatment for:

  • weed control
  • pest control
  • to increase lawn growth

These treatments can be used together for an overall better lawn rejuvenation result.

How Long To Wait To Mow After Lawn Treatment?

There is no definitive answer to this question.

However, time frame aside, the answer is not right away. Give your treatment some time to work and be effective.

Read our article to find out how to mow after a specific lawn treatment and why you should wait before mowing your lawn after a treatment. This information is applicable to all types of traditional lawn mowers, including robotic lawn mowers.

We will also give you some other useful information and mowing tips that will benefit your lawn maintenance.

Lawn Care Pest Treatments

Weed Control

Weed killers are herbicides. These chemicals will kill or prevent the growth of unwanted vegetation, namely weeds, that can affect the growth of the grass.

Weeds compete with the grass for water, soil nutrients, and sunlight.

Disease Treatment and Prevention

Fungicides are used to treat and prevent fungal diseases that can distress grass blades. Examples are brown patches, powdery mildew, and dollar spots.

A couple of home treatments are with baking soda. Spread as a powder or mix with water and spray to kill fungus and create an alkaline environment.

Neem oil is also known as an effective fungicide.

Lawn Growth Treatment


This process can greatly improve your lawn. It involves applying essential nutrients to the soil, which can help improve the grass’s health.

These include nitrogen, phosphorus, and potassium.

Take note: It is best to test the soil to figure out the best fertiliser for your grass.

Should I Mow Before Lawn Treatment?

This may be a little off topic, but it is also important to know.

We give a little advice on whether to mow or not before a pesticide or fertilising session.

Should You Mow Before Or After Pesticide Treatment?

Generally speaking, you should avoid mowing your lawn within 24 hours of any herbicide treatment because there will not be enough leaf area left to absorb the weed control if you mow right before an herbicide treatment.

A broadleaf weed control will not work if it does not come into contact with enough of the plant’s foliage.

Should I Mow My Lawn Before Fertilising?

Is it better to aerate my soil before applying fertilizer, and when is the best time to do so?

When your grass is actively growing, which is in the spring or early fall, you should ideally rake and mow your lawn before applying fertilizer.

This will help ensure that the fertilizer reaches the soil more easily.

How Long Should You Wait To Mow After Spraying For Weeds?

You should wait at least 48 hours before mowing after using a lawn treatment.

Most weed killers and herbicides are absorbed through the leaves and work to the root to eradicate the unwanted plant.

Mowing too early may inhibit the effect of your herbicide; hence, waiting 2 to 4 days can help the herbicide perform better.

How Long Should You Wait To Mow Your Lawn After It Has Been Fertilised?

To allow maximum absorption and for the fertilizer to take effect, one must wait before mowing their lawn again.

Generally, 24 to 48 hours are recommended. Please note that this may vary from fertilizer to fertilizer, so some may require more or less time.

Other factors that may influence wait times are:

  • Environmental factors: a warmer and more humid setting may drive up the absorption rate compared to drier conditions
  • Grass height: having fairly short grass will aid in the even distribution of the fertilizer and avoid clumping, leading to less time required for absorption

What Happens If You Cut Grass Too Soon?

It will take some time for one’s grass to recover from a recent treatment like fertilisation before you can get back to your regular routine.

It takes time for potassium, phosphorous, and nitrogen to seep into your soil and for insecticides and weed killer chemicals to take effect. This process will be hampered if you make any major changes to your yard, such as cutting the grass soon after.

Ideally, one should cut just before treatment, so there won’t be a problem with the waiting period.

Do I Have to Water My Lawn After Treatments?

This is specific to one’s lawn treatment.

Most encourage watering after treatments to nourish the lawn and aid with moving the treatments (nutrients) to the root of the lawn. As a general rule, wait at least 24 hours after applying a lawn care treatment before watering the lawn.

However, make sure the lawn gets thorough watering after the first 24 hours during the first 10 to 14 days following the application.

How Long To Stay Off Grass After Treatment?

Stay off the grass for at least 72 hours, especially young children. They are susceptible to being harmed by the toxic chemicals in the treatments.

This time frame is applicable to herbicides, fertilizers, insecticides, and fungicides.

How Long After Lawn Treatment Is It Safe For Pets?

The same applies to pets as to yourself and your children – a time frame of approximately 72 hours is advisable.

Take note to always read the instructions on the product labels, as some products may vary. There may be either longer or shorter wait times. There may also be a watering instruction before the lawn is safe again.

Are Lawn Treatments Good For The Environment?

Are Lawn Treatments Good for The Environment

In general, it’s critical to thoroughly weigh the possible effects of lawn treatments on the environment and make an effort to use them wisely.

With most treatments, working to make the lawn thrive becomes hazardous to anything that threatens the lawn and prevents a balanced ecosystem. Reduce the environmental impact of lawn treatments by using appropriate application methods.

Traditional lawn treatments have environmentally friendly substitutes. IPM (Integrated Pest Management) techniques, which emphasise prevention, monitoring, and the use of targeted treatments sparingly, can help lessen the need for pesticides.

Composting, utilising organic fertilisers, and encouraging healthy soil are examples of organic lawn care techniques.

These organic methods can help create a more environmentally responsible and sustainable method of maintaining lawns.
