A plant cultivation device for a garden. The plant cultivation device comprises a cultivation table (1). The cultivation table (1) is internally provided with a grid of holes (2). Each of the grid of holes (2) is provided with plant cultivation mud. A transmission slide rail (4) is mounted at one side of the cultivation table (1). Two ends of the transmission slide rail (4) are respectively provided with a transmission motor (5). One of the transmission motor (5) is connected to a watering device via a transmission sprocket-wheel (6). The watering device comprises a water storage bottle (8) and a watering tube (7). The water storage bottle (8) is provided above the transmission sprocket-wheel (6). The watering tube (7) is provided above the grid of holes (2) via the transmission sprocket-wheel (6). A nutrient solution is filled into the water storage bottle (8) of the plant cultivation device for the garden. The transmission sprocket-wheel (6) drives the watering tube (7) to move to apply, in a small area, the nutrient solution to a seedling (3) being cultivated in the plant cultivation mud. The transmission motor (5) drives the transmission sprocket-wheel (6) to move inside the transmission slide rail (4) to drive the watering tube (7) to move, performing large-area watering with the nutrient solution. The watering operation is easy, achieving mobile watering with an adjustable watering area.L'invention porte sur un dispositif de culture de plantes pour un jardin.
