The intelligent watering flowerpot system capable of giving a prompt comprises a flowerpot and a mobile terminal receiving prompt information from the flowerpot. The flowerpot comprises a temperature and humidity detection module, a light detection module, a fertilizer concentration detection module, a water injection module, a flowerpot communication module, and a control module. The control module performs analysis according to the detection information sent by the temperature and humidity detection module, the light detection module and the fertilizer concentration detection module, and then determines whether the soil in the flowerpot needs to be watered or whether fertilizers need to be added or the light intensity needs to be increased; when determining that the watering is needed, the control module sends a control instruction to the water injection module; and when the fertilizers
