Can You Walk On Grass After Fertilizing? (Exploring the Risks)

Your lawn grass requires fertilizer to grow well, thus lawn care is essential. But, can you walk on grass after fertilizing?

For the fertilizer to work, your lawn grass has to be undisturbed for some time. Ideally, it’s best not to walk on your lawn for 24-72 hours after distributing fertilizer. During this time, kids and pets must not be allowed on the lawn as it can harm them. 

Can you walk on grass after fertilizing? All You Need To Know

When the lawn is not disturbed during this time, the fertilizer gets absorbed into the ground and roots of the grass. 

Can You Walk On Grass After Fertilizing? 

Staying off the grass for 24-72 hours after applying the fertilizer is best. However, the duration may change due to different factors, including the type of fertilizer and the weather condition. Liquid fertilizer is absorbed much more quickly in the soil than granules.

How Long Should You Stay Off The Grass After Fertilization

But it’s difficult to determine which fertilizer forms soak completely in the soil. When it comes to weather conditions, fertilizers get absorbed much more quickly. It’s best to avoid fertilizing during a rainy day to avoid a runoff. 

Reasons to stay off the lawn after fertilizing

In addition to letting the fertilizer do its work, there are many other reasons to stay away from the lawn for at least 72 hours after fertilization. Check out all the reasons below.

1. Spreading Fertilizer Everywhere

The rain or sprinklers will wash some of the fertilizer you have added to the soil. Now if you walk on this wet fertilized grass, you will be tracking the fertilizer everywhere. Besides, the fertilizer, the old bit of grass clippings, dry leaves, and other debris mixed with the fertilizer will also spread throughout your home. 

2. Tracking Grass Clippings

Grass clippings have nitrogen and other nutrients that might be washed in the rain. You don’t want your lawn to be full of these clippings; thus, avoid walking on the lawn and wait for the grass to recover and rejuvenate from the fertilization. 

Tracking Grass Clippings

The ground absorbs all fertilizers in small quantities. If your grass clipping spreads, it will create a barrier between the soil and the fertilizer and will not allow the grass to get nourishment. It’s best to deal with the grass clippings while mowing to avoid their later spread.

3. Harmful Chemicals

Your pets and kids will be exposed to harmful chemicals if they start to play and walk on the grass. They might track those harmful chemicals in the home. Besides the chemicals in the fertilizer can contaminate their food and water causing an array of health hazards. If your dog starts licking its paw after walking on recently fertilized grass, it may suffer from nitrogen poisoning. 

4. The Law

Walking on newly fertilized grass is illegal in some areas like Fairfax Virginia. The authorities might call you in if your neighbors complain. Besides, if the chemicals slip into your water supply or your pet’s and child’s food, the consequence will be disastrous. 

5. Uprooting Nitrogen-Sensitive Grass

Walking across a sod lawn during hot summer days is not advisable. The grass is under pressure at this time of the year due to the heat and lack of water. Walking on such grass might dislodge a mat of roots and damage the grass. 

Uprooting Nitrogen-Sensitive Grass

It’s best to do outdoor activities on the lawn in the early morning or late evenings to avoid significant damage to the grass. If you are fertilizing using nitrogen, be very careful about the timing.

It’s best not to apply nitrogen when the temperatures are high. (above 27 degrees Celsius) and showers are not forecasted for the next 24 hours. Nitrogen can lead to grass burns on tissues due to the salt they contain. The risk is high if the fertilizer was recently applied. 

How To Deal With Grass Burn? 

The best way to fix fertilizer burn on grass is by watering the lawn thoroughly. However, avoid overwatering. The grass mostly takes 7-14 days to recover from the burn. However, if it has been badly damaged, it may not recover.
