Controlling thatch is one of the most important and most overlooked parts of lawn care. Thatch is simply the layer of dead grass, roots, and debris that accumulates between the soil surface and the green grass blades above.
Removing soil plugs helps to increase oxygen levels and strengthen the grass' roots. It allows water and nutrients to travel to the roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn.
Fertilizing influences grass color, ability to recover from stress, and helps prevent weed invasions and disease. Nitrogen is every lawn's most important ingredient, and each type of grass demands different amounts to display peak growth and performance.
