Gardening Term: Overseeding

Definition:

Overseeding is a gardening practice that involves spreading grass seed over an existing lawn to improve its density and appearance. This technique is commonly used to fill in bare patches, repair damaged areas, or introduce new grass varieties to an established lawn.

Why is it recommended to mow the existing grass short before overseeding?

Before overseeding, it is highly recommended to mow the existing grass short. This step is crucial for several reasons:

Promotes seed-to-soil contact: Mowing the grass short exposes more soil, allowing the grass seed to come into direct contact with the soil. This contact is essential for successful germination and establishment of the new grass seed.

Reduces competition: By mowing the existing grass short, you reduce the competition between the established grass and the newly seeded grass. This gives the new grass seed a better chance to receive sunlight, water, and nutrients, which are vital for its growth.

Improves seed distribution: Shorter grass allows for more even distribution of the grass seed. It prevents the seed from getting trapped or hidden among taller grass blades, ensuring that the seed is spread evenly across the lawn.

Enhances seedling access to resources: Mowing the grass short increases the availability of resources such as sunlight, air, and water to the newly germinated seedlings. This promotes their healthy growth and development.

Prevents shading: Taller grass can cast shadows on the ground, which can hinder the growth of the newly seeded grass. By mowing the grass short, you minimize shading and allow the new grass seedlings to receive adequate sunlight.

Overall, mowing the existing grass short before overseeding is a crucial step that sets the foundation for successful seed germination and establishment. It maximizes seed-to-soil contact, reduces competition, improves seed distribution, enhances resource access for seedlings, and prevents shading. By following this recommendation, you can achieve a lush and healthy lawn through the process of overseeding.
