Pros And Cons Of Dethatching Lawn


  • It improves sunshine, water, and air penetration. Dethatching makes it possible for sunlight, air, and water to reach the roots of the soil. The turfgrass becomes healthier due to its more profound and vital roots. Grass with a deep root system is more resistant to heat and drought.
  • It lessens susceptibility to illnesses. There is a lack of free oxygen under anaerobic conditions caused by thick thatch. Sclerotinia homoeocarpa, the fungus that causes Dollar Spot in turfgrass, and other disease-causing fungal species thrive in such situations. Your turf’s vulnerability to fungi infections is decreased by dethatching.
  • The penetration of fertilizer is increased. Thatch creates a vegetative wall. Dethatching removes the barrier and makes it easier for fertilizer to permeate the soil. When fertilizer is added to the ground, most turfgrass varieties remain healthier and grow back more quickly.


  • It makes weeds more likely to grow in your yard. Any weed seeds buried in the earth are shielded from sunshine, air, and moisture by thatch, which acts as a barrier. As a result, it aids in reducing the germination of weeds. The weed seeds are exposed to ideal development circumstances when turfgrass is detached.
  • The soil may get dry after thatching. The amount of heat from the atmosphere and direct sunshine that reaches the ground is constrained by thatch. Thatch prevents soil moisture loss and decreases evaporation. The soil is exposed to direct sunshine and heat retention when you dethatch your lawn. It results in more evaporation. Because of the drought or lack of soil moisture, turfgrass may even perish.
  • Frost vulnerability is increased by dethatching. Thatch keeps the soil warm by preventing cold air from getting to the ground during the colder months. Therefore, grass with thatch is less vulnerable to frost harm. After dethatching, the lawn becomes less cold-tolerant and more susceptible to winter frost damage.
