Abstract: A multicavity planter having separable opposing sides and a base with abutting partitions extending from the sides and base at spaced apart intervals to divide the enclosed space into separate cavities. The abutting partitions have flanged edges on one partition in overlapping relation with the sides of another partition to limit root growth between cavities. Releasable pin and socket connections hold the partitions together and the walls of the cavities are sloped to retain the plants in the cavities until they are ready for transplanting. Depressions in the base are provided through which holes may be punched to irrigate plants in the cavities.
