I claim: 1. 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. 2. The plant watering device of claim 1 wherein said cone base has an internal diameter and said second unthreaded cylinder has an outer diameter such that said cone base frictionally fits about said second unthreaded cylinder. 3. The plant watering device of claim 2 wherein the second unthreaded cylinder of the first portion has on its internal surface, adjacent its free edge, a circular bead. 4. The plant watering device of claim 1 wherein said cone base has an outer diameter and said first unthreaded cylinder has an inner diameter such that said cone base frictionally received in said first unthreaded cylinder. 5. The plant watering device of claim 1, wherein the first and second unthreaded cylinders do not have the same length. 6. The plant watering device of claim 1, wherein one of the first and second cylinders of the first portion has a length which is about one third the length of the other of the cylinders of the first portion. 7. The plant watering device of claim 1, wherein said first and second unthreaded cylinders each have a wall and wherein the walls of the first and second unthreaded cylinders do not have the same thickness. 8. The plant watering device of claim 7 wherein one of said first and second cylinders comprises an inner cylinder of the two upper first and second unthreaded cylinders, said inner cylinder being sufficiently thin so as to have a certain resiliency, appropriate to facilitate forceful introduction of the cone base into the interior of the annular gap delimited between the first and second unthreaded cylinders. 9. The plant watering device of claim 1, characterized in that the one of the first and second unthreaded cylinders is of variable thickness. 10. The plant watering device of claim 9 wherein the one of the first and second unthreaded cylinders has a wall with an external diameter, the wall of said unthreaded cylinders has a wall with an external diameter, the wall of said unthreaded cylinder having an end that is integral with the disc and a free edge, the external diameter of said wall decreasing approximately 0.3 mm from the end that is integral with the disc towards the free edge thereof, said unthreaded cylinder having an external face thereby being provided with a slightly conical shape with its base being thicker, and thus more rigid, than its free edge, which is thinner and thus more flexible. 11. The plant watering device of claim 1 including an adapter; said adapter defining a hollow passage and having a first externally threaded end sized to be received by on of the internally threaded cylinders of said fitting second portion, and an internally threaded second end, said second end being sized, and the threads being shaped, such that said adapter second end can be threaded on to a commercially available bottle. 12. The individual plant watering device of claim 1 wherein said cone is hollow. 13. The individual plant watering device of claim 1 wherein said porous cone meters a predetermined amount of water in a determined period of time. 14. A plant watering device comprising: a porous tip portion having a hollow base, the hollow base having an inner surface and an outer surface; said tip portion being configured and disposed to meter the delivery of liquid through said tip portion into soil below a surface of the soil 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 a second surface, said first and second surfaces being on opposite sides of said disk; a first portion including a first unthreaded member and a second unthreaded member, said first and second unthreaded members each extending from the first surface of said disc, said first and second unthreaded members defining an annular space that is sized to receive the hollow base of the porous tip portion and a second portion comprising a first internally threaded cylinder and a second internally threaded cylinder, said first and second internally threaded cylinders each extending from the disc second surface; said threaded cylinders being sized and their threads 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 a neck 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 neck formed with a second diameter. 15. The plant watering device of claim 14 wherein one of said first portion members is shorter than the other of said first portion members. 16. The plant watering device of claim 14 wherein one of said first portion unthreaded members has a wall which varies in width, said wall being narrower at a free end thereof than at a base of said wall; whereby, said member is sufficiently thin, at least at its said free end, so as to have a certain resiliency, appropriate to facilitate forceful introduction of the cone base into the interior of the space delimited between the first portion cylinders. 17. The individual plant watering device of claim 14 wherein said porous tip portion meters a predetermined amount of water in a determined period of time.
