The best way to sow grass seed, and the way we strongly recommend, is with a mechanical spreader. These spreaders come in many varieties but all function the same basic way. By adjusting the distribution rate these device help to ensure a uniform, consistent spread. This consistency makes for a more efficient use of grass seed and eliminates the patchiness often resulting from hand spreading. Here is a closer look at the different types of mechanical spreaders on the market:
Hand-held Broadcast Spreaders – These are some of the most common and least expensive types of spreaders available. The spreader is held with one hand while the other hand cranks on a handle, flinging the seed over a distance as you walk across an area. These spreaders work great for smaller lawns but aren’t practical for large lawns or sports fields. Flow rate accuracy and quality can also be questionable on some models.
Tow Behind/Push Broadcast Spreader – These types of spreaders fling seed just like the hand-held versions, but are wheeled across the ground instead of carried and are much more efficient for large areas. However, what you make up for in speed and efficiency you lose in precision. Best used for large open areas.
Drop Spreaders – Drop spreaders are also wheeled and pushed/towed along the ground, but instead of flinging seed over a distance they “drop” seed from the bottom of the spreader in a very precise, controlled manner. Drop spreaders are an excellent choice for seeding irregularly shaped lawns and keeping seed out of flower beds, sidewalks, etc. but are more time-consuming than broadcast spreaders.
Slit Seeders – Slit seeders are engine-powered machines that cut small groves into the soil and place the seed directly into these slits all in one pass. They offer unmatched efficiency, accuracy, and seed-to-soil contact and produce some of the best results, but are tricky in tight areas. Used extensively by professionals and can also be rented by homeowners.
