The sowing standards for seeds are very different and range from 10 do 30 g na 1 m2, depending on the size of the seeds and the type of lawn.
Covering the seeds after sowing can be done in two ways. The first is to shallowly mix the soil with a rake or spike. This method does not cover all the seeds and some remains on the surface, while the covered seeds are at different depths, which causes uneven germination and emergence. The second way is to cover the sown surface with a one-centimeter layer of soil, which makes it possible to cover all seeds and creates better and even conditions for germination. This method is more laborious, but it should be used there, where we care about a good quality lawn (sport fields).
The sown grasses emerge after 7-14 days, depending on conditions.
The soil to be covered should be fairly loose, that it does not cause crusting of the surface after heavy rainfall. Covering the seeds with a mixture of earth and peat fines gives very good results, which creates better conditions for humidity and air access.
The surface of the area after covering the seeds should be rolled with a light roller for the final leveling and creating better conditions for soaking..
Seeds to germinate require adequate moisture and, if the soil is excessively dry, the lawn should be watered. It should be watered with a strongly dispersed stream of water and gradually, so as not to cause the surface to crust. The amount of water should be this, that it soaks to a depth of 2-3 cm.
When the grass grows 5-10 cm high, the first mowing must be carried out. The lawn can be mowed by hand - with a scythe or mechanically - with a mower.
There are two types of mowers that differ in the way they are cut. The first - a drum mower - consists of one horizontally positioned stationary blade and several obliquely positioned blades on a rotating shaft. Mowers of this type are manufactured as manual and equipped with an internal combustion engine. The second type of mower is lawn mower, rotary, made of a knife motor located on the axis, rotating in the horizontal plane.
The first mowing should only be carried out with very sharp scythes or mowers, because still poorly rooted grass can easily be torn off. For this reason, it is recommended to roll the lawn lightly after the first mowing.
After the first mowing, it is a good idea to feed the lawn with a small dose (0,5—1 kg na ar) calcium nitrate.
How often the lawn is mowed depends on the quality of the grasses used, the strength of their growth, the purpose of the lawn and very often on the technical possibilities.
The cutting height of the grass is from 3 do 5 cm. It is recommended to maintain a higher level of pruning in periods of long-term drought, which results in better shading of the soil surface.
The next mowing should be done then, when the grass grows to a height of 4-6 cm. This occurs after 7-10 days. Therefore, it is highly recommended to mow garden lawns at weekly intervals. Mowing every two weeks can already cause a lot of weeds and lodging and rot of the grass, and such places are yellow after the grass has been cut. Mowing too rarely causes a very uneven development of the different grass species used in the mixture, which greatly reduces the value of the lawn. Infrequent mowing also promotes the appearance of various plants, often completely undesirable.
Mowing garden lawns too infrequently results in their destruction or transformation into meadow lawns with a completely changed plant composition.
The grass clippings may be removed from the lawn surface or may remain as very finely chopped pieces, forming the lawn litter, if mowing is performed with mechanical mowers.
Raking the clipped grass is necessary after mowing with the scythe. Modern mower mowers are equipped with special tanks, mowed grass falls into.
The lawn soil must not be loosened with the tools normally used for this purpose. Special tools are used to loosen the soil on lawns, the so-called. aeratory, that is, ventilators. They work by making holes at intervals to allow air to reach the roots. This treatment should be carried out after raking the lawn of dead grass remnants in the spring and several times during the season. Frequent use of the ventilator on compact soils is particularly recommended.
In the period of drought it is necessary to water the lawns. The amount of water used for watering should be this, so that the soil is soaked to a depth of 10-15 cm. At this depth, the root density is greatest, and this water also enables the use of nutrients in the soil. Sprinkling lawns with a small amount of water is undesirable, because this water does not penetrate into the root zone and cannot be used by the plants. The best watering time is in the afternoon. In big cities, due to the limitation in the use of tap water, watering can also be done at night.
Different types of sprinklers are used for watering. Rotary sprinklers are the most commonly used.
Lawn weeds are most effectively controlled by proper and not neglected mowing. Frequent mowing reduces the growth of weeds and prevents flowering and seeding. Weeds from the group of dicotyledons, occurring on the lawn, can be controlled chemically with herbicides. These measures (e.g. Pielik or Chwastox) apply according to the recipe on the packaging.
