Let’s be real – if you have ever stood in your backyard after a nice rain with your mower, you have probably asked yourself: “Can you mow wet grass or do I need to wait?” That is a good question… and the answer? Leave that mower alone – you are not ready yet.
Mowing wet grass may not seem like a big deal, but it is one of the easiest ways to destroy your lawn – and even potentially damage your mower! Let’s discuss what is so bad about mowing wet grass, how long you should wait after it rains, and what time of day is best to mow grass to avoid damaging it.
Why You Shouldn’t Mow Wet Grass
Here’s the deal – when grass is wet, it is weaker. The blades of a mower are not cutting the grass like the sharp knife that it is. It is tearing it! This means ragged edges, uneven growth, and a lawn that is more susceptible to diseases.
Let’s also not forget the mess! Wet grass clippings will stick together and form large clumps which will block sunlight and air movement. If you have ever had yellow patches of grass after mowing wet grass, it was probably due to clumps.
If you don't know when to mow or want Lawn Mowing Services to give you a professional cut, all you have to do is let Yardful Lawn Services manage everything and keep your lawn healthy and tidy.
The Dangers of Mowing Grass When It’s Wet
Still think cutting is good right after a rain? Here are the downsides of mowing wet grass:
- Slippery lawns – Wet grass + soft soil = easy slipping and falling.
- Mower issues – Wet clippings can plug up your mower deck area and dull blades quickly.
- Uneven cutting – Instead of standing tall, wet blades of grass bend over, giving an uneven look to the lawn.
- Health risks – Torn grass is more susceptible to the northern winter fungus and lawn diseases.
Long story short, wet mowing is harder on your lawn and your mower.
How Long to Wait After Rain to Mow Lawn
This can depend on how much rain we received. Did we issued a light sprinkle? If some sunshine comes out for a few hours, that can be enough to dry the grass. Did we see a heavy rain? You may have to wait until the following day.
The rule of thumb is to wait until the grass is dry to the touch if you walk across the yard and your shoes are wet? The grass isn't ready.
And yes - this applies after watering too. Mowing after watering the lawn can cause the same clumping problem as mowing after rain.
Best Time to Mow Lawn
So what's the best time to mow the lawn without stressing it?
- Mid-morning (8–10 AM) → Dew has dried, but it’s not so hot.
- Late afternoon to early evening (4–6 PM) → Cooler temperatures, results in less stress on your lawn.
Wondering is it better to mow in the morning or evening? Both are acceptable - just do not mow too early (still wet with dew) or around noon (too much heat).
You see, when choosing the best time to mow the grass, if you can mow after dew has dried or when it is cooler it helps a lawn look good in the short term and helps keep a lawn healthier in the long run.
