Abstract: Method and device for planting pot plants with a planting machine travelling on the ground so that a planting furrow is formed by means of a plough-share. The plants are fed into a planting device of the machine. The planting device grasps a plant, lowers the plant down towards the planting furrow, and lets the plant loose above the planting furrow. Thereupon, the plants having assumed a substantially vertical position in the planting furrow, the planting furrow is closed by a pair of pressing wheels. As the plant is detached from the planting device, the component of the speed of the planting device and of the plant, opposite to the direction of travel of the machine, in relation to the machine, is substantially higher than the speed of the machine in relation to the ground.
