# When should you dethatch your lawn? 

That depends on a few factors, including the type of grasses that are growing in your yard, the season, and how well your lawn is taking care of itself. However, most homeowners will want to dethatch their lawn during the summer months when grass growth is heaviest. Here's how to do it:

1. Calculate how much grass needs to be removed. To accurately determine how much grass needs to be removed, first measure the width (in inches) of the section of lawn that you want to dethatch. Next, divide this number by 3 to get an estimate for the actual amount of grass that needs to be removed. For example, if you want to remove 10 inches (1/3 of your yard) from the length of your lawn, then you need to take out a total of 3 inches (10 divided by 3). Divide this number by 1,000 and multiply it by .75. This will be the amount of dethatching chemicals that you will use for this section of your lawn.

2. Measure the ground in front and behind the area that you'd like to dethatch. To accurately determine how much grass needs to be removed, measure down 30 inches or so into the soil and up another 30 inches or so into the topsoil.

## Preventing a Thatch Problem

A lawn that is matted down with a layer of dried leaves, straw, or grass will not look its best. This is due to the fact that water cannot get to the soil beneath the surface and the plants are unable to take in nutrients. Not only does this create an unattractive lawn, but it can also be harmful to the plant's health.

There are several ways to avoid a lawn that is filled with a thatch layer. The most important step is to make sure your lawn is properly watered. Over-watering can lead to excessive growth of vegetation which will create a thatch layer. Make sure to check the ground for signs of moisture levels every day and adjust watering accordingly. Another way to prevent a thatch problem is to use a lawnmower that has a Mulching Function. This will help reduce the amount of grass cut and encourage the growth of groundcover which will help prevent a thatch problem.
