The invention relates to an intelligent flowerpot. The bottom of a pot body is provided with a weight sensor by which the water for irrigation is weighed, and during overweight, a direct-current stepping motor is started by a control circuit board to drive a top cylinder to rotate, so that water intake holes in a water inlet partition plate arranged at the top of a barrel body at the bottom are plugged by water plugs on a drainage plate to stop water from entering, the water intake holes are actively closed according to the detected water quantity, and excess watering is effectively avoided; and meanwhile, the outer wall of the pot body is provided with a water holding gutter, so that excess water is prevented from falling on surrounding objects.
