Do you know what overseeding is? Even if you mow your lawn regularly, there are further problems that can arise.

Overseeding is used for filling up uncovered spots, clotting turfs, and protecting your lawn against harmful insects. It also helps to enhance the beauty of your lawn.

The overseeding process is seeding new seeds into the older grasses. This process helps to keep the consistency of the grasses in your lawn. You won’t feel like there is less grass.

Overseeding saves your lawn from looking dull and old. It allows the lawn to keep a fresh look every day.

Dethatching and Aeration

Petals, grass parts, flowers, and fruit from nearby trees often fall into your lawn. These are known as thatch. A lower amount of thatch is suitable for your lawn.

But a bigger amount can create a layer. This layer works as a barrier to the soil. Therefore air can’t pass through the soil for this barrier.

Dethatching clears excess thatch and keeps a helpful layer.

On the other hand, your lawn’s surface can become hard because of pressure and weight. Aeration process loosens the soil by removing small parts.

The grasses of your lawn can grow well by using this process.
