Claim:
A plant watering device comprising: a porous cone formed from a porous material; said porous cone being configured and disposed to meter the delivery of liquid into soil below a surface of the soil; said cone having a base defining a circumferential wall; and a fitting; said fitting comprising: an intermediate portion in form of a disc having an aperture at its center; said disc having a first surface and second surface, the first and second surfaces being on opposite side of said disc; a first portion including a first unthreaded cylinder extending from the first surface of said disc, and a second unthreaded cylinder extending from the first surface of said disc, said first and second unthreaded cylinders being concentric with each other and defining an annular gap sized to receive the circumferential wall of said cone, at least one of the first and second unthreaded cylinders being resiliently deformable so as to retain the base of said cone; and a second portion including a first internally threaded cylinder and a second internally threaded cylinder, said first and second internally threaded cylinders extending from the disc second surface; said first and second internally threaded cylinders being concentric with each other, the threaded cylinders being sized and the threads of said threaded cylinders being shaped such that said threaded cylinders can be threadedly connected to commercially available bottles of different bottle opening diameters, the second portion including a first lip projecting from the second surface and disposed between the first threaded cylinder and the second threaded cylinder, the first lip being sized and shaped to engage and form a seal with a bottle having an opening formed with a first diameter, and a second lip projecting from the second surface and disposed between the second threaded cylinder and the aperture, the second lip being sized and shaped to engage and form a seal with a bottle having a opening formed with a second diameter.
