Manual sowing of seeds on the lawn

Sowing seeds by hand in the lawn is the most common, but can only be done well by an experienced worker. This sowing consists of throwing the seeds in an arched motion over a distance 1-2 m. The disadvantage of this method is that the seeds fall very unevenly: large seeds fall closer due to air resistance, while the smaller ones go further. Therefore, manual sowing must always be carried out in two crossing directions. For the same reasons, manual sowing cannot be done in windy weather. The effects of air resistance can be prevented to some extent by mixing the seeds with the same amount of moist sand as the seeds.

To protect against difficult to control decreases or increases in the number of seeds per 1 m² in relation to, according to the projected quantity, it is necessary to divide the area of ​​the sown lawn and the whole seed lot intended for sowing into the same number. This makes it possible to easily control the sowing density, and most of all it protects against spreading, all seeds before the lawn is completely seeded.

Manual sowing is convenient for small areas. Large lawns, above all, high-quality lawns, should be covered as soon as possible. Left on the surface, especially quite smooth, they can be blown away by the wind or eaten by birds.

After sowing, the seeds may be at different depths and intervals, depending on the smoothness and texture of the soil surface. It confirms the need to smooth the surface before sowing. Regardless of the method of covering, seeds at different depths will emerge unevenly. Seeds with a depth greater than 2 cm give plants weakened or, after germination, not reaching the surface. The optimal seed depth for most grasses is 1 cm. Seeds at a depth of less than 0,5 cm generally find no conditions for germination, unless the soil surface is specially covered and watered.
