Top Reasons Why You Shouldn’t Cut Your Grass When It Is Wet

Sometimes we only do things at the moment we think about it, and if we don’t do it right away, we forget about it.

The same is true about cutting grass.

And if you are like me, you think about cutting your grass when you see it raining outside.

But make sure to avoid cutting your grass while it is still wet.

Reasons to not cut your grass while it is still wet include the wet grass causes clumping of the grass and could clog your lawnmower, it can spread disease among your lawn, your lawnmower can cause wheel ruts in the grass, you could slip on the wet grass, the wet grass will stain your clothes, it can cause damage to your lawn, the grass is harder to cut when it is wet and much more.

Read on to find out the best reason for yourself as to why you shouldn’t cut wet grass.

Why you shouldn’t mow wet grass

There are many reasons why you shouldn’t mow wet grass, whether it is personal reasons or for the life of the grass.

Read the below to find a pretty extensive list as to why you shouldn’t mow wet grass.

1. Disease

Depending on how you cut your grass, you are either bagging up the grass or letting it mulch and go back out onto the lawn.

Mulching the grass and letting it go back out on the lawn is a good way to self-fertilize your lawn.

So there is a lot of benefit to mulching the grass.

But when you mow the grass when it is wet, there is a concern of passing on disease that you need to worry about.

Wet grass more easily spreads the disease around the yard.

2. Clogging and clumping

There is a lot that damage that can be done from wet grass, and that includes clogging and clumping.

When your grass is wet, it is more likely to stick together.

So instead of blades of grassing coming out of your lawn mower, you will find clumps of grass coming out.

First, these clumps can clog up your lawn mower, especially if you are using a battery powered mower.

Battery powered mowers are notoriously not as strong as gas powered mowers.

So while not having to go to the gas station every once in a while to get more gas is nice, the battery-powered mowers are not as strong.

If you decide to mow your grass when it is wet, your lawnmower might struggle to move around the clumped-up grass.

Especially away from the lawn mower.

So you will find yourself having to stop the lawnmower every so often to pull clumps of grass out from underneath it so you can continue going.

Not only do you have to worry about the lawnmower stopping and starting and having to unclog the lawnmower, but you also have to worry about these clumps of grass around your lawn.

Clumps of grass on the lawn are not nice.

Since they are in clumps, they tend to not be able to dry out as quickly as non-clumps of grass.

And because of this, the clumps are basically shading the grass underneath it.

Which means you might find the grass underneath dying because it isn’t getting enough sun.

So you can either leave the clumps there and watch the grass die, or you can spend more time on the lawn by pulling out a rake and breaking up the clumps of grass.

3. Patterns that are too deep

People will sometimes change up the pattern of mowing the lawn so they have a nice checkerboard pattern on their lawn.

There are a few benefits to this and if you want to read more on this, read another one of our articles.

But mowing the lawn when it is wet might cause some issues with the patterns that you are creating.

Some people will call this problem “wheel ruts”.

You see, since the lawn is wet, the ground underneath it is going to be wet as well.

And this means that the soil and grass are going to be softer.

And because it is softer, it is easier to leave impressions in it.

The wheel from the lawn mower can leave impressions, and deep impressions at that.

Depending on the weight of the lawnmower, you could be leaving deep wheel ruts that won’t go away.

A riding lawnmower, for example, is pretty heavy and most likely will leave wheel ruts all over your yard.

A push mower might not leave wheel ruts, but is it really worth chancing it?

Once you have wheel ruts, there is very little you can do to get rid of the wheel ruts without much work.

A rake might be able to help you, but could just hide the wheel ruts instead of solving them.

Moving around soil and grass could again help a little, but might just hide the wheel ruts.

So the wheels are going to cause ruts in the grass, which might look good at first, but eventually might not disappear.

4. Slippage

Outside of what might happen to the grass, you need to think about what could happen to you.

And slipping on the wet grass is one thing you should consider.

Wet grass is much like a wet floor in your kitchen, where one wrong step could cause you to go slipping and sliding across the floor until you end up getting hurt.

And pushing around a machine that has dangerous blades, might not be the best time to be slipping around the yard.

This will be especially true if you have a lawn that is sloped either upwards or downwards.

Upwards, you could end up falling backwards, with the lawn mower following behind you.

And downwards, you could end up rolling down the hill, with again the lawn mower following behind you.

So it might not be worth the risk of hurting yourself just to cut the grass at the time you are thinking of it.

5. Stained clothing

If you are like me, you’ve mowed the lawn wearing sandals or light colored shoes.

And if you are like me, you’ve learned quickly that your feet or your shoes quickly start looking green.

You can usually take a shower to get the green off your feet or take an old tooth brush to the shoes to remove the green color.

But when you are mowing the lawn while it is still wet, that color might be a little bit harder to get out.

Since the grass is wet, it has a better chance of getting deeper into your clothing.

So avoid cutting grass while it is wet if at all possible.

And if you do forget and you cut the grass anyway, treat the grass stains immediately, since they are easier to get out if treated right away, instead of waiting.

6. Damage to the lawn mower

Outside of having to unclog the lawn mower every once in a while, you also have to consider what the wet grass is going to the lawn mower.

Most, if not all, lawn mowers are going to be made of some type of metal.

And metal, if it stays wet long enough, is going to rust.

Even if you put your lawnmower away right afterward, there is still a chance that not all areas are going to get as dry as it needs to be.

And with that, if you truly want to take care of your lawnmower, you will have to do some more in-depth maintenance work once you are done cutting the wet grass.

This includes scraping the base of the lawn mower, to get rid of the wet grass.

It also includes cleaning off the blades, as well as applying a layer of WD40 to keep the rest of the lawn mower from rusting.

So in the long run, it will cause less work for you and potentially less damage to the lawnmower if you avoid cutting wet grass.

6. Electrocution?

This one depends on what kind of mower you have.

If you have a gas powered mower, you might be fine here.

But if you have a battery powered, or one that plugs into a socket, you might consider whether or not you want to chance getting electrocuted.

Electricity and water don’t mix, so having a battery powered mower does put you at some risk of getting electrocuted.

But if you have a lawn mower that needs to be plugged in, you are definitely putting yourself in danger.

Plugging your lawn mower in and then laying the cord on the wet grass is asking for trouble.

7. Harder to mow

Wet grass is difficult to mow.

Since it is wet, it is more likely to flop around and not stand up straight.

So if you go with the wet mow option, you are less likely to get an even mow to your lawn.

And you might have to live with uneven grass or having to go over the grass multiple to get it to look normal.

8. Mow right before

If you know a rain storm is coming, or just a little bit of rain, consider mowing the lawn right before it rains.

This gives you a few benefits.

First, you can skip a day of watering the lawn.

If you are billed by your city for your water, your next bill might be a little less.

Second, the grass is going to recover more quickly if it receives moisture right after the grass is cut.

So if you cut it right before the rain comes, your grass will benefit greatly from it.

The rain also brings nitrogen down into the soil, which helps the grass grow.

So giving it a good cut before it rains is a good idea.


Overall, it is a better idea to mow the lawn before or a few hour after the rain instead of right after it rains.

There are so many things to consider as to why you shouldn’t do it, that it is just better to avoid it.

You don’t want to get hurt and you don’t want to hurt your grass or your lawn mower in the process.

So either cut the grass before or after it rains, if you can time it right.
