The lawn in rolls or "clods" is a natural lawn that is supplied as if it were artificial, ie in rolls. Except that the rolls are not made of synthetic material, but of real grass, cultivated and cured for about a year and a half. After the maturation of the same, the lawn is cut to a thickness of about one and a half centimeters, keeping intact the roots that must literally attach themselves to the ground in a completely spontaneous and natural way. These sod lawns are cut into rectangular sections and rolled up to be put up for sale and installed in private gardens or public parks. Turf lawns have many advantages over traditional lawns. Among these advantages certainly stands out that of not having to sow the turf from the beginning. But the practicality of the rolling lawn it also concerns the reduction of other care and maintenance interventions, such as frequent irrigation, fertilization and re-sowing.
The turf grass it is marketed and installed by companies specialized in agricultural and gardening products. In particular, these meadows are cultivated and created by farms which, having large arable spaces available, reserve them for the production of turf in rolls. The companies that produce sod lawns create turf suitable for any need, type of terrain and climatic condition. On the market there are rolling lawns for sports use, consisting of ryegrass and poa pratensis. These are lawns that require sunny exposure, with very fine grass, suitable for trampling and with an excellent aesthetic result. There are also sod meadows with thicker grass than the previous ones, consisting of a mixture of fescue to which a small percentage of poa pratensins is added. These lawns are suitable for acidic soils and require sunny or partial shade exposure. These are ideal solutions for those who love rustic or purely rural environments and for areas characterized by intense periods of drought. Another solution of rolling lawn is represented by the clods made up of a single grass, the agrostis, which gives the lawn a very fine appearance similar to that of golf courses. With an excellent aesthetic result, these rolls are placed in sunny positions and on acidic or sandy soils. For gardens and public places with swimming pools, rolled lawns are used consisting of cynodon, a micro-thermal grass that grows at high temperatures and resists even in the hottest climates. These meadows are ideal for areas characterized by severe drought and widely used in summer. The appearance of the cynodon rolled lawn is very fine, even if the turf resists frequent foot traffic. The laying of these rolls is not recommended in the winter period.
The turf grass it is delivered wrapped in rolls tied by a net. But before "unrolling" the turf and placing it on the ground, the soil must be properly prepared. To avoid the growth of weeds, the soil should be sprinkled with a specific herbicide at least two weeks before being worked. After this period, the soil must be excavated to a depth of 15 centimeters. For the excavations you can use the classic manual hoe or the motor hoe. Fertilizer, preferably phosphorus-based, must be added to the worked soil, which helps the development of the root system of the turf. The fertilizer should be distributed in the order of about thirty grams per square meter. The soil must then be finished with a rake, taking care to eliminate stones or other large components, such as pebbles and debris. The last operation of land arrangement is rolling, that is, the flattening of the surface by means of a machine with a cylindrical wheel (roller) which makes the soil well leveled and suitable for laying the lawn in rolls. After the ground has reached the ideal conditions for laying, the turf can be added. The clods should be arranged starting from the farthest area of the field, to avoid trampling the lawn while transporting the rolls.
Lawn in rolls must also be cut in order to keep the grass level constant and uniform. Roll cutting or mowing of the lawn should be done in spring, at least once a week, although it is advisable to do it twice. With shaving, the grass thickens and prevents the appearance of weeds. The ideal size of the cut should correspond to no more than one third of the overall height of the grass. The cut must be carried out with a lawnmower equipped with a new blade, in order to make a clean cut and not to fray the grassy edges. To perform an error-free cut, the lawn grass must also be completely dry.
Lawn maintenance is not only carried out with cutting, but also with irrigation and fertilization. The rolling lawn should be irrigated as each clod is laid. To facilitate the operation, special portable sprinklers connected to a hose can be used. At the end of the installation, the rolling lawn must be watered abundantly. The frequency of watering will depend on the type of grass used for the sod and the season. In summer, several irrigations a day may be required: the important thing is to avoid the dryness of the clod. To check the degree of humidity of the same, just lift it from the ground. In the hottest hours of the day it may be necessary to use larger quantities of water, in order to better irrigate every corner of the rolled lawn. Even the rolling lawn, in order to remain healthy and luxuriant, needs adequate fertilization. The fertilizer must be distributed on the clods at least three times a year, if necessary even four, three months between each intervention. The ideal fertilizer is made up of a higher amount of nitrogen, a medium amount of potassium and a low amount of phosphorus, in the spring, and an equal amount of nitrogen and potassium in the summer and winter, because potassium helps the grass to resist extreme temperatures.
Rolling lawn: Costs
The prices of the rolled lawn vary according to the manufacturer, the quality of the clods and the surface to be covered. Prices are generally set per square meter and vary from eight to fifteen euros per square meter, with peaks that can even reach 18 euros. To these costs must also be added those of maintenance. For a complete view on the costs of the rolled lawn it is advisable to ask for a quote from various manufacturing companies.
