Slit-seeding is accomplished with a machine that slices rows into your lawn and drops seed into the slits. The knives are designed to slice into the lawn rather than rip out thatch. This reduces the damage to the lawn, leaving the lawn relatively undamaged. There is still a small amount of thatch kicked up, but it is minimal compared to what a dethatcher creates.
Here are a few things to know about our professional slit seeding service:
We only use premium certified grass seed.
The seed is customized to your requirements in order to address problems like disease, insects or poor color.
We strongly recommend a double aeration prior to the slit seeding. This helps break up any thatch layer, reduce soil compaction and the cores of soils act like a topdressing when they are smashed up by the slit-seeder blades.
Starter fertilizers are applied to ensure fast root establishment of the newly germinated seeds.
We also recommend our Organics Plus Topdressing to further enhance seed establishment.
The topdressing supplies a broad range of micronutrients and also acts as a mulch.
Overseeding is very similar to slit-seeding. The difference is that overseeding involves broadcasting the seed with a rotary spreader as opposed to dropping it with a slit-seeder. Overseeding alone is not as effective as slit-seeding, but can be if it is followed up with a power rake.
Maintain good soil moisture for the first four weeks.
It's important to keep the soil moist because the tiny roots of the newly germinated grass seeds are shallow and they can quickly dry out and die. This means watering the newly seeded areas lightly each morning. After four weeks the lawn can be watered like a mature lawn.
Wait until the lawn is to 1/3 higher than you normally mow before cutting. Ensure that your mower blade is sharp to achieve a clean cut.
Be gentle for the first few mowings.
Take corners carefully and mow before watering (when the soil is relatively dry). Mowing a lawn that has wet soil can compact the soil and inhibit proper root establishment. Walking a mower over a soft wet soil can also rip roots and rut the soil.
