Abstract
Abstract A method of caring for plants is carried out by utilizing a planter that includes a soil container having openings at the bottom thereof for communication to a basin. The container is filled with liquid to a level at which substantially all of the soil is submerged in the liquid and remains so for a selected period of time. Then an aperture at the bottom of the basic is opened and the liquid in the container drains through the openings at the bottom of the latter into the basin and exiting therefrom through the aperture. In another embodiment a transparent siphon is utilized to remove liquid from the basin and is also utilized as a sighting means so that a user is aware that liquid in the container has reached a desired level. Salts that often accumulate at the soil surface are run off by having liquid enter the container through the openings at the bottom thereof and run out of the container above the soil line.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
Planter apparatus including: a first container for holding a planting medium, said first container having perforations at its bottom; a basin disposed below said perforations to catch plant nourishing liquid that drains from said first container through the perforations thereof; and selectably operable drain means through which liquid is withdrawn from said basin to a level that is substantially below the perforations; said drain means including a siphon tube having a bend intermediate an inlet and an outlet, which bend is normally disposed above both said inlet and said outlet at an elevation approximately that of planting medium disposed within said first container; said inlet being in communication with said basin and being substantially below the perforated bottom of the first container; said outlet normally being disposed outside of said first container and below said inlet.
Claim 2
Dependent Claim
136 words
Planter apparatus including: a first container for holding a planting medium, said first container having perforations at its bottom; a basin disposed below said perforations to catch plant nourishing liquid that drains from said first container through the perforations thereof; and selectably operable drain means through which liquid is withdrawn from said basin to a level that is substantially below the perforations; said drain means including a siphon tube having a bend intermediate an inlet and an outlet, which bend is normally disposed above both said inlet and said outlet at an elevation approximately that of planting medium disposed within said first container; said inlet being in communication with said basin and being substantially below the perforated bottom of the first container; said outlet normally being disposed outside of said first container and below said inlet.
Claim 3
Dependent Claim
20 words
Planter apparatus as set forth in claim 1 in which the perforations extend through the bottom of said first container.
Claim 4
Dependent Claim
35 words
Planter apparatus as set forth in claim 1 also including means defining a space which extends from said basin upward to approximately the height of a planting medium that is disposed within said first container.
Claim 5
Dependent Claim
51 words
Planter apparatus as set forth in claim 3 in which the means defining the space is constituted by a vertical channel outside of said first container, with at least a major portion of the means defining the space being formed integrally with a second container having said first container disposed therein.
Claim 6
Dependent Claim
25 words
Planter apparatus as set forth in claim 1 also including a pan disposed to receive liquid that discharges from said basin through said drain means.
Claim 7
Dependent Claim
63 words
Planter apparatus as set forth in claim 1 also including a vertical channel disposed outside of said first container and having a lower end that communicates with said basin near its bottom, and said inlet being disposed at said lower end; said siphon tube also including an inlet portion between said inlet and said bend, which inlet portion extends vertically in said channel.
Claim 8
Dependent Claim
35 words
Planter apparatus as set forth in claim 6 including another channel; said siphon tube also including an outlet portion between said outlet and said bend, which outlet portion normally extends vertically in said another channel.
Claim 9
Dependent Claim
40 words
Planter apparatus as set forth in claim 7 in which the first container near its upper end is provided with overflow aperture means through which liquid drains directly from said first container into said another channel through the top thereof.
Claim 10
Dependent Claim
44 words
Planter apparatus as set forth in claim 1 in which said siphon tube is transparent, at least on the vicinity of said bend, to permit gauging the extent of liquid that fills said basin and occupies said first container for most of its height.
