I claim: 1. A plant watering device comprising: a porous cone formed from a porous material; said porous 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 a second surface, the first and second surfaces being on opposite sides of said disc; a first portion including at least one unthreaded cylinder extending from the first surface of said disc; said at least one unthreaded cylinder and said base of said cone having respective diameters such that said cone is frictionally secured to said unthreaded cylinder; 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 first sealing means disposed between the first threaded cylinder and the second threaded cylinder, the first sealing means being shaped to engage and form a seal with a bottle having an opening formed with a first diameter, and second sealing means disposed between the second threaded cylinder and the aperture, the second sealing means being shaped to engage and form a seal with a bottle having an opening formed with a second diameter. 2. The plant watering device of claim 1 wherein said cone base has an internal diameter and said at least one unthreaded cylinder has an outer diameter such that said cone base frictionally fits about said at least one unthreaded cylinder. 3. The plant watering of claim 2 wherein the at least one unthreaded cylinder 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 at least one unthreaded cylinder has an inner diameter such that said cone base frictionally received in said at least one unthreaded cylinder. 5. The plant watering device of claim 1 wherein said first sealing means includes a first lip on said disc second surface; said first lip being sized and shaped to engage and form a seal with a bottle having an opening formed with a first diameter. 6. The plant watering device of claim 1 wherein said second sealing means includes a second lip on said disc second surface; said second lip being sized and shaped to engage and form a seal with a bottle having an opening formed with a first diameter. 7. The plant watering device of claim 1 wherein said first portion comprises a second unthreaded cylinder; 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. 8. The plant watering device of claim 7 wherein the first and second unthreaded cylinders do not have the same length. 9. The plant watering device of claim 7 wherein one of the first and second unthreaded cylinders has a length which is about one third the length of the other of the first and second unthreaded cylinders. 10. The plant watering device of claim 7 wherein the walls of the first and second unthreaded cylinders do not have the same thickness. 11. The plant watering device of claim 10 wherein one of said first and second unthreaded cylinders comprises an inner cylinder, said inner cylinder being sufficiently thin so as to have a certain resiliency, appropriate to facilitate forceful introduction of the cone base into the annular gap delimited between the first and second unthreaded cylinders. 12. The plant watering device of claim 7, characterized in that the one of the first and second unthreaded cylinders is of variable thickness. 13. The plant watering device of claim 12 wherein the one of the first and second 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. 14. 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 one 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. 15. A plant watering device comprising: a porous tip portion having a hollow base, the hollow base having an inner surface and an outer surface; 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, the first and second surfaces being on opposite sides of said disc; a first portion including a first unthreaded member and a second unthreaded member 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 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 first sealing means disposed between the first threaded cylinder and the second threaded cylinder, the first sealing means being shaped to engage and form a seal with a bottle having an opening formed with a first diameter, and second sealing means disposed between the second threaded cylinder and the aperture, the second sealing means being shaped to engage and form a seal with a bottle having an opening formed with a second diameter. 16. The plant watering device of claim 15 wherein one of said first portion unthreaded members is shorter than the other of said first portion unthreaded members. 17. The plant watering device of claim 15 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; said unthreaded 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 hollow base into the interior of the space delimited between the first portion unthreaded members.
