Unlike general over-seeding where a spreader is normally used to simply broadcast seed over a lawn (hoping grass seed will eventually reach soil to begin the germination process), mechanical slit-seeding ensures critical seed-to-soil contact by slicing through the lawn and planting the seed directly into the soil. Mechanical slit-seeding is best performed in late summer/early fall, but can be completed in the spring as long as NO crabgrass prevention herbicides are used (pre/post slit-seeding). For even better results, core aerate the targeted lawn areas before slit-seeding and apply a granular seed starter fertilizer (high in phosphorus) shortly after. While slit-seeding may not be the most efficient or cost-effective way to plant an entirely new lawn from bare soil, the process really excels when rebuilding an existing lawn that has declined from such issues as disease, heavy physical use, drought, etc..
Mechanical slit-seeding provides excellent seed germination rates and should be incorporated into any professional long-term lawn improvement program.
