Mowing wet lawns: why rain should not be an obstacle and how to do it correctly

Your lawn would urgently need a cut again, but the weather somehow does not play along? It rains every now and then, so that the lawn has no time at all to dry out and you are now beginning to wonder, may and can you mow wet lawns? Don’t worry, a prolonged period of rain or dew is no reason to let your ornamental lawn grow long. After all, the longer it is, the harder it is to trim, and add to that the fact that the growth is further stimulated by the rain. So grab your lawn mower and get to it! However, keep the following things in mind:

Why long periods of rain do not preclude mowing the lawn

Mowing wet lawn - tip what you should pay attention to for proper mowing

The ideal lawn height is considered to be 4 cm and there is still the 1/3 rule. This states that you should not shorten the lawn by more than a third per mowing. So, in order to maintain the said ideal height, the blades of grass should not grow longer than 6 cm. As already mentioned, the more moisture, the faster they grow, so that each omitted mowing, the lawn will continue to grow in height. To bring it back to 4 cm will take some time. For this reason, you should not neglect mowing the lawn and also mow a wet lawn if there is no other way.

Let the lawn rest beforehand

You may not be walking on the lawn at the moment, but it is important to note that you should not do so if you want to mow a wet lawn. If the blades are wet, they will stick together. So if you were to step on them, the blades would not be able to stand up again quickly enough afterwards, but in order to be shortened, of course they should.

Mow wet lawn, but do not mulch to prevent rotting

Mowing the lawn wet or dry – What is the difference in terms of the collection basket?

For one thing, you shouldn’t let the basket get full every time before teaching it for the next load if you’re mowing wet lawns. This is because it is heavier and that, of course, makes the lawn mower heavier and the yard work more power consuming. So dispose of the lawn clippings more often than usual, and make sure they’re really firmly anchored. And if you now, you could just leave out the basket instead and mulch the lawn right away, leaving the clippings lying around as you normally would, be advised: do not do this at all.

The wet grass, unlike dry grass clippings, not only blocks light from reaching the lawn. Moisture also accumulates under it, which can very quickly lead to rotting if there are more rainy days (since the clippings can’t dry). And this will ruin your beautiful, well-kept lawn.

Clean the blades

Mowing wet lawn and cleaning blades regularly

Something you may not be used to from regular lawn mowing is that when the grass is wet, you’ll most likely need to clean the blades in between as well. Again, this is because the blades of grass stick tighter than they do when dry. If large amounts collect on the blades, they will accordingly not be able to do their job and the grass will not be cut evenly.

Note: If you have never cleaned the blades before, you should remember that a gasoline lawn mower must be turned to the right side for this purpose, so that the fuel does not leak.

Mowing the lawn when the grass is wet at the same height as usual?

When mowing the lawn after rain, set the correct cutting length.


If grass is dry, it stands straight up. But if it is wet, the blades bend more or less downwards due to the weight of the water drops, depending on their length. Accordingly, it may well happen that the usual height adjustment does not quite work now. So it would be a good idea to try a higher setting first, rather than a low one right away. This also makes it easier for the lawn mower, and the first pass will also shake the blades a bit drier already.

Special care should be taken with electric lawn mowers

Protect electric lawn mowers from the moisture and dry them

The cable itself is not sensitive to the moisture, provided that it is intact and not damaged anywhere. However, this type of lawn mower, of course, has its weak points, and these are the connections, as well as the plug. And it is these that you should protect from the moisture to avoid short circuits. It goes without saying that you should not mow while it is raining. After you’re done mowing, it’s important to clean and dry the mower well before stowing it away again.

Bonus tip: When was the last time you mowed your lawn?

Why cutting the lawn is important even in the rain and when to mow the lawn last


Especially now in autumn, such periods of rain are of course not uncommon. That also begs the question of when a final fall lawn cut would be appropriate. Of course, it depends on the weather, but in our latitudes this is the autumn , this about the end of October. If the autumn is milder at this time, you can also do another cut later, but not later than mid-November.
