Can You Mow Wet Grass?

Cutting the grass in your lawn when it is still wet is not ideal and there are many reasons why we say so. Even something as mild as early morning dew can still pose danger to both you and your mower.

Therefore, you can only mow your lawn in the morning when the dew has dried. In this post, we will be sharing with you the dangers of cutting wet grass. Are you interested? Keep reading…

Why Cutting Wet Grass is Dangerous for Your Lawn

The most ideal situation in which you should cut your grass is when their leaf blades are standing straight off the earth surface. However, wet grass tends to be much heavier than dry ones which means they’ll likely be bending over from all the weight of the moisture.

Interestingly, when your grass begins to dry, some of the blades will become straight again. However, some other blades may remain in their bent position. When you mow with the grass in this condition, you will successfully cut grasses that are uptight will missing those that are hugging the ground.

Obviously, at the end of the day, when the bent grass assumes their upright position, your lawn will simply look rough and uneven.

But this is not the only downside to cutting wet grass. Typically, when wet grass is cut, they look more torn or ripped apart than cleanly cut. This torn state of the grass coupled with the moisture gives plenty of opportunities for the fungal infection to spread on the grass. So, cutting wet grass means giving room for fungus to gain ground across your lawn.

Also, another way fungal disease can spread on your lawn is through the grass clippings of grass cut after a rainstorm. Because of the moisture, grass clippings tend to form big clumps.

These clumps, when they remain on the lawn for a while, begin to restrict the healthy flow of air to the growing grass thereby killing the plants or stunting their growth.

Besides, wet grass clipping can also cause a fungal infection called black spot. And let’s not forget, certain grass clipping can even cling to the underside of the mower deck thus breeding mould. Meanwhile, this mould can even spread to your grass.

Fungal infection and mould apart, using your mower on a wet lawn can cause serious havoc to the soil itself. First, the wheels of the machine will sink into the soil and form ruts or damage the grass. As if this is not enough, it can also compress the soil and the danger of this will begin to manifest over time.

Why It’s Not Good for Your Mower

First of all, moisture doesn’t go well with petrol in the tank of your mower. It also doesn’t go well with metal parts which means you put the machine’s engine in danger when you expose it to moisture.

Moisture will cause rust if you don’t mix a stabilizer into the oil tank. Also, wet clipping that clings to the mower’s underside tends to cause corrosion. Apart from this, the caked clippings hinder the blade motion of the machine causing it to exert more effort.

All in All, it is Unsafe for You!

No matter how much work your lawn needs, remember that your safety should come first. When you mow your wet lawn, you stand more risk of getting injured.

With the grass wet and slippery you can easy trip and dislocate a muscle or break a bone. However, the danger gets even higher when you’re using an electric mower or working on a sloppy ground.

Green Machinery warned on their reviews of the best corded electric lawn mower’s guide and advised not to utilize electric mower on wet grass, considering that can harm the mower itself (ex: blocking blade rotation etc) or the individual who’s operating.

Eliminate the risk of injuring yourself on a sloppy ground by growing ground covers on them and not grass. This way, at least you won’t slip one day and accidentally position your legs before the blade of your powered mower.

Did You Know That Mowing a Wet Lawn is More Work?

Mowing a wet lawn requires more effort and time. Interestingly, despite all your hard work, you’ll later realize how ineffective the mowing was and you will want to trim the lawn again to make it look better.

What’s more? Working in a wet lawn means exposing yourself to mud. This also means that your clothes and shoes will need a thorough washing, and that is only if they’re not completely ruined

If You Have to Mow While Your Lawn Is Wet, Use These Tips

Sometimes, we just can’t help it. We all have that “mowing must be done and must be done now!” Moments. We understand. But that doesn’t make it ideal.

Anyway, if the rain just won’t stop falling in your area and your grasses are getting dangerously high or you’ve put your home on the market and you wish to impress prospective buyers with a great looking lawn, go ahead and mow. However, make sure to use these tips.

  • Sharpen the blade of your mower
  • Mix stabilizer in your petrol
  • Raise the wheels of your mower wheels. This will help to reduce the strain on the engine.
  • Don’t bother bagging the grass or mulching it as these can’t be effective with wet grass. Bagging wet turf will get your bag messy and mulching doesn’t work much with wet grass.
  • You can also minimize the strain on your mower by trimming only half the grass swath you usually cut on each pass.
  • Clean the mower deck underside to get rid of clippings. You may want to spray silicon on this part before starting so that the clippings will be easier to remove
  • Gather grass clipping with a rake and transfer them somewhere they can decompose.


To avoid being left with no choice, always pay attention to the weather forecast. This way, when you have to mow your lawn and a storm is approaching you can do it before the rain comes.
