PROBLEM TO BE SOLVED: To provide a greening method which stabilizes an inclined surface (a slope) such as a bank or a sunken road, or efficiently greens the park, the stadium or the like. SOLUTION: The greening method includes: placing a greening planting net 10 obtained by putting Lippia-genus creeping stems (vegetative propagation stems) 1 containing Lippia nodiflora cut off in an appropriate length between nets 2, 3 made of plant fiber such as cotton yarns or planting sheets, and a roll of the long planting net 10 or the long planting sheet using a tractor or the like over a ground 20 to be greened, so as to grow the genus-Lippia containing the Lippia nodiflora while applying joint soil 21 or supplying water.
