DETAILED DESCRIPTION OF THE DRAWINGS

[0023] As shown in the drawings, and particularly FIG. 1, a plant propagation tray assembly in accordance with an embodiment of the present invention comprises a rectangular base tray 2, having a base and upstanding side walls, within which is located a number of inserts 4 (six in the embodiment shown, although any other number of inserts is envisaged) are located in side by side relationship, each insert 4 comprises a row of cells 6 (five cells in each insert in the embodiment shown, although any other number of cells is envisaged) within which individual seedlings 8 may be placed in a suitable growth medium.

[0024] As best shown in FIGS. 2 and 3, each cell 6 of each insert 4 has an open top and an open front side to facilitate inspection and removal of the contents thereof when the respective insert is removed from the support tray 2, wherein the open sides of the cell 6 of each insert 4 are closed by the side walls of an adjacent insert when the inserts 4 are located in the support tray 2 in side by side relationship, or by an end wall of the tray 2 in the case on an endmost insert 4A.

[0025] Each cell 6 of each insert 4 comprises a first side wall 10, opposing second and third side walls 12,14 extending perpendicular to the first side walls 10, and a base wall 16. The open side of each cell 6 is located opposite said first side wall 10 thereof. The first side walls 10 of the cells of each insert 4 are aligned in a common plane, and may be defined by a common wall extending the length of the respective insert 4. The first walls 10 of the cells of each insert 4 also serve to close the open sides of the cells of an adjacent insert 4 when the inserts 4 are located in the support tray 2. The ends of each insert incorporate upper lips 5 arranged to rest upon an upper edge of the support tray when the inserts 4 are located in the support tray 2, supporting the inserts 4 within the support tray 2 and facilitating removal of the inserts 4.

[0026] The second and third side walls 14,16 of the cells 6 of each insert 4 may comprise common partition walls separating the cells 6 of each insert 4.

[0027] A drainage hole 18 may be provided in the base wall 16 of each cell 6 of each insert 4.

[0028] In use, the inserts 4 are placed in the support tray 2 in side by side relationship and a seedling 8 and a portion of a suitable growing medium are placed into each cell 6 of each insert 4. During growth, the condition of each seedling 8 may be readily inspected by lifting a respective insert 4 out of the support tray 2, exposing the open side of each cell 6 thereof. Any diseased or infected seedling may be readily removed and/or replaced before the respective insert 4 is replaced into its place in the support tray 2.

[0029] As shown in FIGS. 4 to 6, when it is desired to remove the seedlings from the cells 6 of each insert 4, for repotting in larger pots or for planting into the soil, each insert 4 in turn may be readily lifted out of the support tray 2 and may be tipped forwardly to allow the seedlings 8 in each cell 6 of the respective row to be tipped out from the open sides of the cells 6, as illustrated in FIG. 6.

[0030] As shown in FIG. 7, in one embodiment the first walls of each cell 6 of each insert 4 may be formed from a first wall portion 10B defining a rear wall of the respective cell 6, said first wall 10B being slightly inclined to the vertical, and a second wall portion 10A, defining a common vertical rear wall of the insert 6, said second wall portion 10A fitting against and closing the open side of a respective cell 6 of an adjacent insert 4. The second and third side walls 12,14 may be similarly inclined to give each cell a tapered shape, narrowing towards the base wall 16 thereof. This arrangement of tapered interior walls of each cell allows the inserts 6 to be supplied in stacked configuration, while the vertical second wall portion 10A ensures reliable closing of the open side of a respective cell of an adjacent insert thereby.

[0031] In an alternative embodiment, shown in FIG. 8, the first, second and side walls 10,12,14 of each cell may be arranged vertically so that each cell has a cuboid shape.

[0032] As illustrated in FIGS. 9 to 11, the inserts 6 may be adapted to be coupled to one another when placed in the support tray 2. In the embodiment shown, projections 22 are formed at a distal edge of outermost side wall of the end cells of each insert 6, said projections being receivable within female coupling members 24 integrally formed on the rear wall of the insert adjacent the outermost side walls thereof. It is envisaged that alternative coupling arrangement may be provided, including detachable clips.

[0033] The plant propagation tray of the present invention thereby greatly facilitates inspection of the seedlings during growth and facilitates quick and easy removal of the seedlings from the cells, when desired, without damage to the seedlings, thus overcoming the problems associated with the prior art.

[0034] The invention is not limited to the embodiments described herein but can be amended or modified without departing from the scope of the present invention.
