Preparation of the ground
Ground is defined as a solid area covered with topsoil or any specially prepared bearing layer on which turf-grass is going to be laid. Soil needs to be properly prepared. Soil should be prepared by skimming off any old trees or shrubs, removing large stones or gravel, and then be roughly forked over. Perfectly prepared soil should be airy and permeable, therefore sometimes there is a need to add some sand to gain that effect. All these steps are the best ways to prepare the soil before laying turf.
Laying turf on:
Turf is rolled out so that rolls are placed tight next to one another on the previously prepared ground. It is crucial to handle the turf gently without throwing it and stretching it too much. Right after installation, the turf has a proper humidity, but it drops after time. It makes the turf shrink – therefore, if it is not properly placed, there will be visible gaps between the rows. That is why a proper turf laying technique is so crucial for the future appearance of the lawn. It is extremely important to lay the rolls tight next to each other. Moreover, turf should rather be pushed right up to each other rather than stretched. All the edges that run beyond the area must be trimmed with a sharp knife or a saw blade. After a finished work, the lawn should be rolled and thoroughly sprinkled with water.
On slopes and embankments the laying technique is the same as in case of flat areas. If the slope is steep, turf should be pinned at the corners with wooden pins (4 to 10 pieces). It prevents the turf from sliding before grass roots penetrate the soil.
Areas which are extremely steep or have unfriendly conditions for grass cultivation are the most challenging areas to lay turf (car parks, green belts on motorways). It is mainly because these areas are not easily accessible. Most frequently, the main purpose of such lawns is the protection against erosion. Moreover, lawns make such areas visually more attractive.
Irrigation is one of the most crucial things when it comes tom maintenance of the already laid turf-grass. It is important to irrigate not only the topsoil (couple of meters) but also 10 cm of lawn’s bearing layer. This will make roots grow downwards. 10-151/ m2 of water is an optimal amount for a single sprinkling. As time passes, breaks between sprinkling should become longer. Frequency and amount of sprinkling should, of course, be adjusted to the local climate and weather conditions. Freshly laid turf-grass during first weeks must be regularly irrigated so that it is constantly humid before the root system develops. In cases when turf needs to be laid on problematic areas, where technical difficulties connected with proper irrigation may occur, we recommend laying turf on colder and cloudier days.
