Sowing the lawn

Sowing the lawn

There are basically two types of sowing: hand sowing, generally applied to small surfaces, based on broadcast distribution, and machine sowing with broadcast or row distribution, for larger sizes. Sowing by hand does not guarantee calibrated and uniform distributions, to optimize this method we recommend operating in the absence of wind and dividing the total sowing dose into four equal parts, each of which will be distributed crosswise on the sowing surface. The doses vary in relation to the type and species of seed desired, however it should be remembered that a too sparse sowing lengthens the growth times of the rind and favors the settlement of weeds. A too dense sowing, for its part, generates several inconveniences: the fast-germinating essences occupy the space of the slow-germinating ones, therefore we will have an uneven lawn, moreover the too much density keeps the humidity level high, favoring the onset of diseases . For broadcasting with machines, the distributor will be calibrated in order to spread half the seed longitudinally and half crosswise. The machines on their part can be of two types: with gravity or centrifugal distribution. A further sowing technique is that in rows: in this case the machine must be calibrated for a spacing not exceeding 2.5 cm. With these machines there is a good coverage of the seed and in general it is sufficient to carry out a single pass. It should also be borne in mind that when the seeds chosen are particularly small, it is good practice to add inert materials such as sand to improve their distribution on the ground.

At the end of the sowing, a small covering of the ground will be carried out which can be done by hand with a rake for small areas, while for larger extensions a very light harrow will be used. Alternatively, topdressing can be used, which distributes a light layer of fine material such as sand on the surface. In the presence of very light and dry soil it is good to do a light rolling, which will have the purpose of bringing the soil close to the seed and favoring the rising of humidity which contributes to faster and more uniform rooting. The sowing period is one of the factors that determine the success of a turf: germination takes place in a sufficiently humid climate and with temperatures between 15 and 20 degrees. In Italy these conditions occur in the periods of September-October and March-April. In any case, autumn sowing is to be preferred as grasses are able to grow and develop more rapidly. If in some point the conditions of the turf worsen, you can also proceed to overseed: after having mowed the lawn and passed the aerator to remove the felt and moss, a regeneration type seed is distributed, to be covered with a little topsoil. Finally pass the roller. By watering regularly, the new grass will germinate within a few days, giving your lawn a compact appearance.
