Claim:
1. A vessel for holding a plant comprising interior, bottom, and side portions, and having a watering pad containing particles of superabsorbent polymeric powder and located at said bottom potion of said vessel, said pad connected to a source of a water-containing liquid, said pad comprising a first film joined with a second film, said first film having an adhesive coated first side surface located on an inside surface of said pad and an opposed second side surface located on an outside surface of said pad and said second film having a first side surface located on an inside surface of said pad and an opposed second side surface located on an outside surface of said pad, said first and second films being sufficiently brittle for said particles of superabsorbent polymeric powder to penetrate and break through said first and second films, said particles of superabsorbent polymeric powder of sufficiently large size to penetrate and break through said first and second side surfaces of said first and second films, said particles extending through said first and second side surfaces of said first and second films through openings created by penetration and breaking through said first and second films by said particles thereby creating free volume for said particles to expand into to cause enhanced liquid absorption rate when in contact with said liquid, said broken through particles spaced apart from each other to minimize touching of said broken through particles and directed into said interior of said vessel.
