When To Mow When Dethatching Your Lawn

You will need to mow your lawn twice when you are dethatching the lawn. First, you will need to mow at the start.

The shorter grass will make it easier for a rake or vertical mower to penetrate the ground. As a result, you can remove more of the thatching.  

When you are doing this, you will need to mow it shorter than you normally would. It’s best to cut the grass at half the regular height. 

At the end of the dethatching process, it’s common for your lawn to look a little messy. There will often be some organic matter, and soil spread out across the grass.

Because of this, you might want to mow the lawn again. This will allow you to make sure that your lawn looks neat. 

For the final mow, you need to be careful about the mow height you are using. You often don’t need to cut too much of the blade off, placing further stress on the grass. 

Tips To Minimize Grass Stress When Mowing for Dethatching

While mowing is an important part of the dethatching process, it will place a lot of stress on the grass.

The good news is that there are some ways to prevent this, these tips include: 

  • Choose a cool time of the day. You should be mowing in either the mornings or the afternoon. The heat of the day will significantly reduce moisture levels in the grass. 
  • Use a sharp blade. A blunt blade will rip the grass blades, rather than cutting them precisely.  Plus, maintaining a sharp blade will make mowing a lot faster. 
  • Don’t take off more than a third of the grass blade. When you first mow the lawn to prepare it for dethatching, you will need to cut it a little shorter than normal. But it’s still important to pay attention to the amount of grass blade you are removing. Because of this, you might need to make multiple passes over a few days. 
  • Give it some time to recover. After the first mow, you should leave a day for the lawn to recover from the stress. Similarly, you should leave a day after you have finished dethatching. 
  • Only dethatch in mid to late spring. This is when the grass is growing most strongly. As a result, it will be able to recover easier. Performing this procedure at the wrong time of the year can prove to be fatal for your lawn. 

Though these are simple steps, they will have a huge impact on the health of your lawn.

How Long Does It Take for The Grass To Recover From Dethatching?

  • Spray with pre-emergent pesticides. Your lawn will be especially susceptible to weeds after you have dethatched. Using this spray should help you ward off potential pest species. 
  • Deep drench the lawn. Both dethatching and mower will remove moisture from the lawn. As a result, it’s important to find some ways to add this water back to the soil.

You should also spread out other organic debris, like leaves. 

Finally, you might want to consider using a mulching mower. As the name suggests, this will break down the clippings as you mow.
