As may be determined by a review of the above patents, the prior art does not teach nor contemplate a fertilizer packet of the type described herein for placement in the base of a plant pot.

3. General, Summary Discussion of the Invention

While the prior art has taught a variety of various types of fertilizer packaging for placement into the soil, none has contemplated a fertilizer pack comprising a special¬ ly formulated fertilizer and filtering medium contained by a -configured package of fluid permeable fabric having wicking properties, the package further comprising a skirt or flange of the same material.

The present invention overcomes the above prior art problems by providing a system utilizing the above briefly described device, which is specifically formulated for the particular type of plant used therewith, and sized to fit in the base of the desired pot for optimal performance.

In use, one merely selects the appropriately sized fer¬ tilizer pack for the pot being used, places the pack in the base of the pack with the skirt or flange extending up the inner sidewalls of the pot, fills the pot with potting soil or the like, and places the desired plant into the soil.

Upon watering the plant, the present invention serves five functions, namely 1) the cloth or fabric package, in conjunction with the gravel therein, acts as a filtering medium to prevent soil from being washed out of the pot; 2) the fertilizer contained in the package is "slow released," providing an extended infusion of nutrients to the plant which, after a transplant, is critic*-³—o the continued

health of the plant; 3) the "skirt" or flange, in conjunction with the main body of the pack, acts to retain moisture, preventing all of the water from escaping from the drainhol- es; 4) the wicking action of the cloth of the package and "skirt" act to direct water from the base of the pot up the side walls of the pot, where the newly transplanted plant's root system will be able to receive the water; and 5) the gravel in the packet allows any excess water to drain from the pot, through the gravel and the pot through any holes in the pot.

It is thus an object of the present invention to provide a system for the potting of plants which provides for greater ease, in preparing the pot and soil for transplanting of plants.

It is another object of the present invention to provide a device for use in the potting of plants, with the device preferably providing fertilizer, drainage, a filtering medium, a means to retain water, and a wicking medium in an inexpensive and easily used package.

It is a further object of the present invention to provide a device for use in the potting of plants, which is placed into the base of the pot prior to planting, with the device preventing the egress or loss of soil from the drain holes of the pot, while at the same time promoting appropri¬ ate drainage.

It is still a further object of the present invention to provide a fertilizer pack for use in potting plants or like activity, with the fertilizer pack containing an extended release fertilizer mixture preferably designed to promote optimal growth for the particular type of plant being used therewith.

Lastly, it is an object of the present invention to provide a fertilizer pack for use in the potting of plants which is available in a variety of size, packet and skirt configurations, whose use is dependent upon the size and shape of the pot being used therewith.

DETAILED DESCRIPTION of the PREFERRED.

EXEMPLARY gHBQPIHENT(S)

As can be seen in Figures 1 and 3, the gravel/fertilizer packet P of the preferred, exemplary embodiment of the present invention, comprises an outer containing package 16 of cloth or the like. The outer fabric package 16 of the preferred, exemplary embodiment comprises a somewhat config¬ ured, main body 1 having an upper, first wall 2, a lower, second wall 3, and an edge 4.

Emanating from the edge 4 about the periphery of the main body 1 is a skirt or flange S. Skirt S, as included in the preferred embodiment of the invention, is comprised of the first (2) and second (3) fabric walls forming the main body 1, which are affixed at the edge(s) 4 via sewing, heat fusion, glue, or like means. In the present, preferred embodiment, the edges 4 are sewn with thread.

As further shown in Figure 1, the skirt S may have cuts or slits 6 made in a perpendicular or radial fashion relative to the main body 1, for^' facilitating accurate and correct placement of the skirt into the pot.

As shown in the cut-away portion of the present figure, first (2) and second (3) side walls are configured to envelope a mixture of gravel 7 and fertilizer 8. The gravel 7, in conjunction with the cloth composition of the walls 2, 3, acts as a filtering medium for the prevention of egress or loss of soil and the like from the plant pot during watering, as will be further explained infra. Figure 2 illustrates the placement and use of the exemplary embodiment of the present invention in a standard plant pot arrangement. As shown, the gravel/fertilizer packet P is placed in the base of pot 9 with the edge(s) 4 of main body 1 substantially communicates with, i.e. in juxtaposition or spaced relatively closely to, the inner side walls and bottom of pot 9, and the skirt 5 extends up along side and is in vertical communication with inner side wall of pot 17.

After placement of the gravel/fertilizer packet P in the base of the pot 9, the desired potting soil 11 is placed thereupon and the plant then transplanted to the pot. A watering dish 10 is desirable in the present system, as placing an amount of water 12 directly into the dish allows the infusion and retention of the water into the pot 9 by the gravel/fertilizer packet's "wicking action" (note direction arrows 14), brought about by the cloth material of the first (2) and second (3) walls, while an optimal amount of fertil¬ izer 8 is released through the main body 1 into the soil for use by the plant. Further,, the skirt 5, in vertical communi¬ cation with the inner side wall 17, is configured and designed to direct the water to the root system of the plant.

The water may be poured directly into the top of the pot as well, wherein it passes through the potting soil and through the filtering gravel into the dish 10, where it may be redirected into the pot when the soil and pack becomes sufficiently dry to promote infusion of the water back into the pot through the drain hole 13. Further, when the water is infused into the soil via the packet through the drain hole(s) 13, the fertilizer, contacting the water, gradually dissolves into the water, where it is directed up the side walls via the skirt to the plant.

The present device is contemplated to be offered in a variety of sizes and shapes, dependent upon the size of the pot with which it is to be used. Exemplary measurements of the exemplary embodiment(s) of the present invention are as follows (in inches) with "G" and "F" standing for gravel and fertilizer respectively:

Diameter of Pot Size

Main Body Thickness Skirt fbase, Mix ure* Weight

3" 3/8" 1" 3" lOZ G, 1 02 F 2 oz

4 1/2" ^* 5/8" 1 1/2" 4 1/2" 3θZ G, 2 oz F 5 oz

6 1/2" . 11/16" 1 1/2" 6 1/2" 6θZ G, 4 OZ F 10 oz

8 1/2" 1" 1 1/2" 8 1/2" 10 oz G, 6 OZ F 16 oz

It is noted that the present invention may be configured to other sizes and shapes, depending upon the type of pot used therewith, and applicant does not intend to limit the present invention to the measurements and amounts set forth above.

The fertilizer used in the exemplary embodiment compris¬ es OCHMITE(tm) 14-14-14 slow dissolving fertilizer mixture which, when used with the present system, is estimated to last approximately four to six (4-6) months under normal conditions. However, other slow-release fertilizers, such as HYPONEX(tm) , for example, may be substituted with similar good results, and special packs may be used incorporating specialty fertilizer for certain plants, such as rose bushes, vegetable and produce, and other flowers such as azaleas, camellias, and the like.

The gravel as used in the present system comprises fine to medium mixed "pea" type gravel, similar to that used in aquariums and the like.

The fabric or cloth as used in the exemplary embodiment of the present invention comprises 100% non-woven RAYON(tm) synthetic fabric, which has been found to provide the desired wicking, fluid retention, and filtering properties as needed for the present invention, and is further desirable in that it is inexpensive, durable, and may be heat fused together, thereby foregoing the necessity for sewing the first (2) and second (3) walls of the present system together. As a more readily bio-degradable alternative, 100% cotton cloth may be used instead of the RAYON(tm); however, because as such cloth is not heat-fusible, it would have to be joined via threaded or adhesive or other suitable means.

As previously stated, the skirt 5 of the grav¬ el/fertilizer packet P may be slit at various areas 6 in perpendicular or radial fashion relative the main body 1 in order to provide a flush fit with the inner sidewalls of the pot, although such slits may not be necessary.

In fabricating the present invention, the 100% exemplary RAYON(tm) fabric may be configured out of stacks of cloth via die cuts, providing a plurality of cloth pieces for assem¬ bling the exemplary embodiment. First and second pieces of cloth would be selected, the gravel/fertilizer mixture placed therebetween and centered, forming main body 1 and skirt 5, and the edges of the main body 1 would be fused, sewn, glued, or otherwise joined.

The embodiment(s) described herein in detail for exemplary purposes are of course subject to many different variations in structure, design, application and methodology. For example, the skirt of the present invention may vary from about a half (1/2) of an inch to over twelve (12) inches, depending upon the size of the pot used, while the diameter of the main body may vary anywhere from a half (1/2) inch to over ten (10) inches, again depending upon the size of the bottom of the pot.

Further, because many varying and different embodiments may be made within the scope of the inventive concept(s) herein taught, and because many modifications may be made in the embodiments) herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
