Abstract
Abstract A watering device for growing plants. A container which may be a flower pot filled with soil or the like which has an aperture in the bottom. A second container for water is provided below the first container. A rigid probe having a central bore is provided that can be inserted through the aperture in the bottom of the first container or pot and extended up into the earth in the container. A wick has a part immersed in the water and a part extending up through the bore in the probe and is then wrapped around the probe and fastened. The probe is axially slotted to allow moisture to be drawn up through the wick and to transfer to the convolutions of the wrapped wick and for dissemination into the soil in the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
A plant watering device including a container containing material for growing a plant, means below the container for holding a supply of water, at least one probe extending upwardly in the container into said material, the probe having a central bore and being perforated so that a passage is provided through said probe between said material and said means for holding a supply of water, and a wick having one end submerged in water contained in said means for holding a supply of water and extending upwardly through the probe and out through a perforation in said probe with a second end of said wick being wrapped around the outside of the probe forming convolutions positioned in contact with said material whereby water can be drawn up through the wick by capillary attraction and into and out through the probe and delivered to the material in the container.
