Why does my lawn get thatch?

What month should I Dethatch my lawn?
The best time to dethatch your lawn is when it’s actively growing and the soil is moderately moist. For cool-season grasses, that’s early spring or early fall. For warm-season grasses, dethatch in late spring through early summer (after the second mowing). That’s when your grass is growing most vigorously.
Do grass clippings cause thatch?
Contrary to a popular lawn myth, leaving clippings on the lawn does not cause thatch, which is a layer of partially decomposed grass-plant parts between the soil and live grass. Grass clippings are mostly water, so as long as you mow regularly at the right height, they will break down and disappear rapidly.
Why is my lawn soft and spongy?
Spongy lawns are the result of excess buildup of old and dead grass material. Overly thick thatch not only makes the lawn spongy but can interfere with the plant’s ability to gather air, water, and fertilizer. The roots are forced to grow on top of the thatch and the sponginess increases.
How do you stop thatch?

To fill in the bare spot, you’ll have to prepare the area for reseeding or laying new sod.
Is a power rake and a Dethatcher the same thing?
A dethatcher is a light-duty tool used to remove thatch that is up to 1/2-inch thick. A power rake is a heavy-duty garden tool primarily used by professional landscapers to lift and remove thatch that exceeds 1/2 inch in thickness.
Should I power rake my lawn?
