To plant a lawn, the site must be organized according to the design elevation in advance. The main operations include digging (planing) the soil, leveling, fertilizing, and if necessary, changing the soil. For lawns with special requirements, such as sports field lawns, groundwater drainage facilities should also be installed. 80% of the roots of lawn plants are distributed in soil layers above 40cm, and more than 50% are within a range of 20cm below the surface. Although some lawn plants can withstand drought and barren conditions, planting on a 15cm thick soil layer can easily lead to poor growth, and management should be strengthened. In order to maintain excellent quality of the lawn and reduce management costs, the soil layer thickness should be as high as around 40cm, and thicker soil layers should be added in areas less than 30cm. For soil containing impurities such as bricks and stones, although it does not have a significant impact on the growth of lawn plants, it hinders management operations. Sundries should be picked out, and if necessary, all 30-40cm thick topsoil should be sieved. If the soil contains substances such as lime that are harmful to the growth of lawn plants, all 40cm thick topsoil should be removed and replaced with sandy loam to facilitate the growth and development of lawn plants.

To improve soil fertility, some high-quality organic fertilizers are applied as base fertilizers. Apply 40-50 t/hm2 of farmyard manure or 15-20 t/hm2 of hemp residue. If phosphate fertilizer is needed, 150-200kg/hm2 of superphosphate can be applied. Regardless of the type of fertilizer applied, it should be crushed and mixed evenly with the soil, and then turned over into the soil. But do not use horse manure, as it contains a large amount of weed seeds, which can cause weeds to tiller in the lawn in the future. To protect the tillers and roots of lawns from underground pests, appropriate amounts of pesticides should be applied while fertilizing. Spread evenly to avoid clumping of powder that may affect the survival of lawn plants.

After completing the above work, level the ground according to the design elevation and pay attention to maintaining a certain drainage slope (generally using a slope of 0.3 to 0.5 degrees). There should be no potholes in the site to avoid water accumulation. Finally, use a roller to gently crush it once. Stadium lawns have higher requirements for drainage. In addition to paying attention to surface drainage (the slope can generally be 0.5~0.7 °), underground drainage systems should also be installed. The quality of land preparation is one of the key factors for the success or failure of lawn establishment, and must be taken seriously.

Lawns, like other venues, need to consider draining surface water. Therefore, when leveling the ground, consideration should be given to drainage issues, and there should be no low spots to avoid water accumulation. Lawns often use gentle slopes for drainage, and a gentle slope trench is built within a certain area. At one end below it, a rainwater outlet can be set to receive the discharged surface water, which can be discharged through underground pipelines or directly connected to the lake through a trench. The ideal flat lawn surface should be slightly higher in the middle and gradually sloping towards the surroundings or edges. Lawns with flat terrain, high groundwater levels, or excessive accumulation of water, as well as lawns in sports fields, should be equipped with concealed pipes or open ditches for drainage. The most complete drainage facility is to use concealed pipes to form a system connected to the free water surface or drainage network. The lawn irrigation system is an important project in the development of lawns. At present, most lawns use sprinkler irrigation. Therefore, before the final leveling of the site, the sprinkler pipe network should be buried completely.
