This invention may, however, be embodied in many differc'" forms and should not be construed as limited to the embodiments set forth hereiln rather, these embodiments are provided so that this disclosure will be thorough ai l complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

As used herein, "plant border" means an amount of growing medium into which a strip of a plurality of plants is fully or partially embedded. The plants may extend upwardly from the growing medium with the roots of the plants embedded in the growing medium. As used herein, "growing medium" means a substance that serves to support and sustain the plants and which is suitable for planting in a desired permanent or semi-permanent location with the strip of plants. Preferred growing mediums include potting soil, pine bark, peat and sand. Other suitable growing mediums include coir, compost and perlite. Exemplary plants which may be grown and planted using the present invention include, for example, Mondo Grass Fescue, Agapanthas, Leriope, flowers and other suitable plant varieties.

With reference to Figures 1 and 10, a plant border system according to preferred embodiments of the present invention is shown therein and generally designated 2. The plant border system 2 includes a tray assembly 20, a fill cover and a support container 30. As discussed in further detail below, the fill cover 15 10 may be used to facilitate installation of growing medium and plants into the tray assembly 20 and the support container 30 may serve to reinforce the tray assembly during filling, growing, storing and handling.

With reference to Figures 1-4, the tray assembly 20 includes a plurality of (as shown, five) plant border trays 100 and an interconnecting web 22. As shown, 20 the tray assembly 20 includes five trays 100; however, more or fewer trays 100 ~may be provided. The web 22 includes a plurality of connecting strips or portions 24 surrounding and interposed between the trays 100. The trays 100 are defined in part by cut lines 25. Preferably, the cut lines 25 extend fully through the thickness of the web 22. The cut lines 25 define a plurality of ties 26 which join the trays 25 100 and the connecting portions 24. The number of ties 26 may be more or fewer than those shown in the drawings. Preferably, the ties 26 each have a length of between about 3 and 30 mm. The ties 26 may be torn or cut using scissors, a knife or the like.

The tray assembly 20 is preferably formed of a continuous, molded, polymeric material. The tray assembly 20 may be formed by molding the tray in the configuration as shown and then die cutting the cut lines 25 into the tray assembly. Suitable polymeric materials for the tray assembly 20 include high impact polystyrene, ABS, PVC and polypropylene. The web 22 and the walls Sforming the trays 100 preferably have a substantially uniform thickness T (Figure Preferably, the thickness T is between about 0.6 and 2 mm.

Preferably, the tray assembly 20 has a length L1 (Figure 2) of between about 350 and 670 mm. Preferably, the width W1 (Figure 2) of the tray assembly 20 is between about 250 mm and 1.2 m. The connecting portions 24 between the trays 100 preferably each have a width W2 (Figure 2) of between about 20 mm and 100 mm. The width W2 of the connecting portions 24 is preferably selected to provide a desired gap for growth of plants in the trays 100 such that the plants of adjacent trays 100 will not grow into each other during the intended period between planting or placement in the trays 100 and removal from the trays 100 (typically between about 45 and 600 days). By providing the desired distance between plants, the plants are provided with room to fill out. The tray assembly provides efficiencies in handling and stability (especially tip-over prevention).

Each tray 100 may be removed from the tray assembly 20 by tearing the ties 26 which secure the tray 100 to the web 22. A tray 100 which has been removed in this manner is shown in Figures 5-9, 11 and 12. As best seen in Figures 5-8, the tray 100 includes a pair of opposed, tapered side walls 110 and a pair of opposed, tapered end walls 116. The bottom of the tray 100 is formed by a pair of flat bottom walls 112, an inverted V-shaped bottom wall 114, and tapered lower comer walls 115. The inverted V-shaped walls 114 assist in stabilizing and S.inhibiting flexure of the trays 100. A reinforcement collar 118 surrounds the upper portions of the side walls 110 and the end walls 116. A flange 120 surrounds the tray 100 and extends horizontally outwardly from the collar 118. The tray 100 defines a longitudinally extending cavity 102 and an upper, longitudinally 25 extending opening 104 which communicates with the cavity 102.

Each tray 100 preferably has a width W3 (Figure 2) of between about and 78 mm. Each tray 100 preferably has a length L3 (Figure 5) of between about 332 and 652 mm. Preferably, the length L4 (as measured from end wall 116 to end wall 116 at the top opening 104; Figure 5) of the cavity 102 is greater than the width W4 (as measured from side wall 110 to side wall 110 at the top opening 104; Figure 5) of the cavity 102. More preferably, the length L4 is at least six times the width W4. Most preferably, the length L4 is between about six and fourteen (14) times the width W4. Preferably, the length L4 is between about 330 and 650 mm and the width W4 is between about 38 and 76 mm. Preferably, the length L4 is at least six times the height H of the cavity 102. The height H (Figure 8) of the cavity 102 is preferably between about 38 and 98 mm.

Preferably, the cavity 102 has a volume of between about 600 and 2300 cm 3 Drain holes 113 are formed in the bottom walls 112. The regions on the flange 120 from which the ties 26 have been torn are indicated by the number 126.

Cutting guide structures 130, preferably guide channels as shown, are molded into the collar 118 on either side. Preferably, the cutting guide structures 130 are positioned a distance D (Figure 7) of between about 50 and 190 mm from the adjacent end wall 116. Additionally, indicia 132 is provided adjacent the cutting guide structures 130 to direct the user to cut the tray 100 at the designated location.

The indicia 132 may be molded into or printed on the tray 100, or may be provided on a self-adhesive label or the like. In accordance with the indicia 132 and using the cutting guide structures 130, a user may cut the tray 100 to form a removed portion 10OB and a remaining portion 100A as shown in Figure 9.

The tray assembly 20and each of the trays 100 may be used in the following manner. With reference to Figure 1, the tray assembly 20 may be e "mounted in the support container 30 and the fill cover 10 may be placed over the tray assembly 20. The support container 30 includes surrounding, upstanding side walls 32 and a mesh or grated bottom wall 34. The bottom wall 34 allows for drainage. Figure 10 is a cross-sectional view of the assembled system 2 of Figure 1 taken along a line corresponding to the line 10-10 of Figure 2 (Figure 2 is a top plan view of the tray assembly 20 only). As shown in Figure 10, the fill cover is configured such that funnel portions 12 thereof extend into the cavities 102 of the respective trays 100. The operator may fill the cavities 102 with growing medium soil) and plants or seeds through the respective openings 14 in the funnel portions 12. Additionally, water, fertilizer and other desired treatments and nutrients may be provided to the plants in the trays 100 through the openings 14.

In this manner, the fill cover 10 serves to direct the various fill materials into the trays 100 and to prevent or minimize the runoff or the collection of these substances on the web 22. The plants are preferably grown in the trays 100.

For filling, growing, storage and handling, the tray assembly 20 may be retained in the support container 30. When it is desired to distribute a plant border 6 to plant the plant border 6, a tray 100 including the plant border 6 may be removed from the tray assembly 20 by tearing along the ties 26 (see Figure 2).

The selected tray 100 and the plant border 6 together form a plant border assembly 101 as shown in Figure 11. The plant border 6 includes a growing medium 7 soil; see Figure 12) disposed in the cavity 102 and a plurality of plants 5 which have roots embedded in the growing medium 7 and which extend upwardly through the opening 104 of the tray 100.

The plant border 6 may be planted in a desired location in the ground 8 by digging or otherwise forming a trench 9 as shown in Figure 11. The tray 100 is cut as shown in Figure 9 along the cut guide structures 130 and the portions of the tray walls 110, 112, 114 extending between the cut guide structures 130. The tray 100 may be cut using, for example, scissors, a knife or the like. The end portion 100B formed by the cut is removed or folded away from the remaining portion 100A to form an end opening 136 (Figure The plant border 6 is then slid out of the remaining tray portion 100A through the opening 136 and into the trench 9 as shown in Figure 12. In this manner, the plant border 6 may be removed from the tray 100 and installed in the trench with reduced or minimal disruption to the S.plant border 6.
