An apparatus (100) for cultivating a plant is disclosed. The apparatus includes a container (102) made of a biodegradable material. The container has a top portion (104), a base portion (106), and a surface portion (108). The apparatus (100) further includes a plant-cultivating medium (110) contained in the container (102). The plant-cultivating medium (110) includes water-retaining hydrogels. The plant-cultivating medium (110) is operable to retain water and to limit release of the water. The apparatus (100) also includes a plurality of tube shaped root channels. A bottom end of a root channel (112a) is close to the base portion (106) and a top end of the root channel is further from the base portion (106). The root channel (112a) is sufficiently wide to allow growth of a root of the plant through the root channel (112a).
