Generally, more than 1,500 kg of grass is used per mu. Grass dressing time should be done after weeding and soil fertigation. General use of winter time (December to January) cut grass garden. The grass is laid to a thickness of about 5 cm, so that the ground cannot be seen. If the grass source is insufficient, it can be paved in the vicinity of the grass, or paved in batches, every other year, first shop the steep slopes of the mountains, and spread the lowland flats afterwards; first lay the thin mountains and then spread the fat mountains. Mountain terraces and terraced tea gardens are free to spread; tea gardens along the slopes have to be laid along the contour line of the tea line, with the grass head pressing on the grass, and the grass blocks the grass to prevent the wind and heavy rain from taking away the grass. The newly planted tea gardens are far from the base of the tea plants.
