     FIELD OF THE INVENTION 
     The present invention relates to the field of gardening. More specifically, the present invention relates to the filed of mobile garden carts. 
     BACKGROUND 
     The present invention relates to gardening carts for the plant or garden hobbyist or horticulturist. An urban gardener frequently is limited in space for plants because of the conventional utilization of living space around the house or apartment. The urban gardener is faced with the choice of dedicating a portion of their living area to the gardening effort and loss of utility of the area or the pursuit of the hobby in full view of visitors. While the trappings of the gardener produce the beauty and joy of mature fruit and flowers, the present invention provides an attractive gardening area that is mobile and will complement the decor of the living space. 
     Moreover, the present invention provides both a decorative and attractive aspect to the gardening function. With the disclosed gardening cart, the structure may be readily assembled and utilized for the period necessary. The gardening cart may then be easily transported to another location. While the structure is functional and sturdy, the simplistic design and assembly provides an attractive help-mate to the gardener. 
     Further application of the present invention may be found in the portability of the gardening cart as used for early planting of vegetable seedlings. In such application, the seedling house may be set out of doors during the warmer, sunny days to encourage the germination and growth of the seeds. The cart is then readily returned indoors for the cool evenings or colder, dark days which could inhibit plant growth. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a kit and device for mobile gardening comprising a base structure, at least one vertical support attached to rear end of the base structure, at least one diagonal support attached between a front end of the base structure and a top end of the vertical support, said diagonal support further comprising a plurality of bracket receiving slots; at least two growing containers, each growing container comprising at least a base and at least on side, capable of holding soil or other plant material, said base have at least one water drainage aperture; and at least two bracket attaching the at least two growing containers to the diagonal supports of the cart. 
     It is another object of the present invention to provide the kit and device for mobile gardening wherein the at least two growing containers are all the same size.

     DETAILED DESCRIPTION 
     The present invention is useful for home gardening. Specifically, it is mobile garden cart that is useful in that it allows relocation of home patio gardens as the user desires. 
       FIGS. 1 to 23  show exemplary mobile garden carts  10  that are suitable for use as an upright terraced growing container system, and their components thereof. 
     The cart  10  according to the present invention comprises a series of planters, or growing containers  20 . These growing containers  20  are preferably attached in a tiered fashion to at least one, preferably two or more supports  30 . The cart  10  of the present invention includes at least two growing containers  20 , though preferably there are three or more growing containers  20 . Preferably the growing containers  20  are symmetrically attached to the supports  30 , but asymmetrical attachment is also considered. Critically, at least a portion of each growing container  20  is directly over the growing container adjacent below (with the exception of the bottom growing container). Thus, the supports  30  must allow the tiered growing containers  20  to be attached in a substantially diagonal configuration, though an arcuate or other configurations are also considered. 
     Each growing container  20  is capable of holding soil or other plant base matter. One preferred embodiment of growing container  20  has a base  22  with two vertical ends  24  and two non-vertical, outwardly angled sides attached thereto. In a preferred alternate embodiment, there is a base  22 , two vertical ends  24 , an angled non-vertical front  26 , a vertical rear  27 , thereby defining an open topped container. In a preferred embodiment, there is also a non-vertical, outwardly angled lip  28  attached to the rear  27 . In a most preferred embodiment, there is a second set of vertical ends  29  inset from the first set of vertical ends  24  attached to the base  22  and rear  27  (see specifically  FIG. 6 ), thereby defining an inset in the back of the growing container  20  which is useful for attachment to preferred supports  30 . Further, a vertical lip  26 ′ may be included by attachment to an upper side of the non-vertical front  26 , for functional or aesthetic reasons. 
     In one embodiment, the growing containers  20  are sized to be stacked inside of each other when shipped in the disassembled state. Critically, each growing container  20  further comprises at least one drainage aperture  21 . These drainage apertures should be located that when water flows through them, the water is received by the growing container below (with the exception of the bottom growing container), thereby reducing water wastage. In one embodiment, not shown, the drainage apertures  21  are located in the base of the growing containers  20 , in a more preferred embodiment, illustrated in the figures, the drainage apertures  21  are located in the non-vertical front  26  adjacent to the bottom  22  of the growing containers  20 . In order to regulate water flow from these growing containers  20 , the present invention also includes at least one drainage aperture plug  21 ′, preferable a multitude of plugs  21 ′. 
     The growing containers  20  may be sectionable by means of at least one partition, not shown, that may be inserted into the interior of the growing containers  20 . 
     The supports  30  of the present invention are preferably generally triangular in shape, each having a horizontal leg  31 , a vertical let  32  any a hypotenuse leg  33 . Located in each hypotenuse leg  33  are at least one, preferably two or more support notches  34 . Each support notch  34  is sized to the bottom  22  and vertical rear  27  of the growing containers  20 . The support notches  34 , preferably, do not extend through the width of the hypotenuse leg  33  in order for the proximal and distal ends of the growing container  20  to extend over a portion of the hypotenuse leg  33  thereby providing stability and aesthetic considerations. However, it is considered that the support notches  34  may extend through the width of the hypotenuse leg  33  and still fall within the scope of the present invention. 
     One preferred base structure  40  is rectangular and four sides, two short sides and two long sides. Another preferred base structure  40  is trapezoidal with four sides, two angles sides, a short side and a long side. Other shapes may be used and still fall within the scope of the present invention. The inside area of the base structure  40  is preferably spanned by a tray, netting or mesh. 
     The base structure  40  is movable comprising at least one movement enabling structure  42 . In one preferred embodiment the movement enabling structure  42  comprises four castered wheels. In another preferred embodiment, the movement enabling structure  42  comprises three castered wheels. In an alternate embodiment, the movement enabling structure  42  comprises four low friction slide pads. Other movement enabling structures may be uses and still fall within the scope of the present invention. 
       FIG. 1  illustrates one preferred embodiment of the present invention wherein the growing containers  20  are curved or arcuate. In this figure, the curve covers 90° of arc, however other curve coverages, such as 45° and 180°, are considered to fall within the scope of the present invention. 
       FIG. 2  illustrates an alternate embodiment of the present invention wherein the growing containers  20  are generally straight. 
       FIGS. 8-11  illustrate yet another alternate embodiment of the present invention wherein more than one, preferably three, straight carts  10 , such as illustrated in  FIG. 2 , may be attached together to form a truncated V shaped assembly. When combining several carts in to a complex assembly, there may be attachment clips or the like that hold the several carts together. These clips may act on either adjacent growing containers, adjacent supports, or adjacent base units and still fall within the scope of the present invention. 
       FIGS. 12-15  illustrate still yet another alternate embodiment of the present invention wherein two straight carts  10  are joined to form a V-shaped assembly. 
       FIGS. 16-19  further illustrates the embodiment first shown in  FIG. 1  wherein growing containers are curved to form an arcuate shaped assembly. 
       FIGS. 20-23  illustrates still a further alternate embodiment where the supports  30  are angled relative to the growing containers  20  to allow the entire assembly to more easily fit within a corner area. In this version, the base  40  of the cart  10  is preferably more trapezoidal in shape. 
     Finally,  FIG. 9  illustrates an embodiment of the present invention that includes a watering system. In one form the watering system is a simple mist or drip system hooked up directly to a hose, thereby allowing for distributed watering. In another embodiment the watering system further includes a water storage tank that is in fluid communication with a water hose, a water metering mechanism such as a float for filling the storage container and a pump for distributing the water and a tree of hoses for fluid distribution of the water from the pump. The ends of the hoses may be either drip or mist distributors. Other watering systems may be used and still considered to fall within the scope of the present invention, such as a horizontal PVC or plastic tube on one side or in the middle of each growing container. Finally there may be a series of apertures in the angled rear lip of each growing container to contain a drip nozzle, thereby hiding from general view the bulk of the watering system.
