ABSTRACT:
An automatic water-supplying flowerpot and its water supply control method are disclosed, in which the principle of capillary action is utilized. The flowerpot of the present invention comprises an upper pot for containing the soil to raise a plant, a lower pot for storing the water, and an intermediate portion for integrally connecting the said upper and lower pots. A water supply control tube which is stuffed with an absorption material extends from the bottom of the lower pot to the bottom of the upper pot in order to adequately supply the water into the soil of the upper pot, the water supply control tube including a large bore and a plurality of small bores. The advantage of the device of the present invention is that frequent waterings are not required, but the watering may be done once for every couple of months, thereby making it possible to leave the flowerpot uncared during a long trip and the like.
