What is a slit seeder?

A slit seeder is a specialized machine used in landscaping or sod installation that efficiently prepares the soil and seeds a lawn simultaneously. Also called a slice seeder or a vertical seeder, this tool saves time and effort compared to more traditional methods.

The slit seeder’s primary mechanism is a series of closely-spaced knife blades that are arranged vertically along a roller. As the machine moves forward, the blades penetrate the soil and create narrow slit-like furrows. These furrows then act as the planting bed for the grass seed.

Evidence suggests that slit seeding gives higher germination rates than traditional broadcasting of seed, as it places them directly into the soil rather than onto the surface. The process also keeps the seed moist and in contact with the soil, which aids germination. Overall, slit seeding is an effective and efficient method for establishing a new lawn or enhancing an existing one.
