ABSTRACT:
A container of the kind used for supplying water and/or nutrients directly into the soil adjacent the plant comprises a bottle for holding the supply of water and a cap structure which encloses one end of the bottle. The cap structure is effective to both support the bottle upright on the soil adjacent the plant and to transfer liquid downwardly from the bottle into the soil. The cap structure includes a spike which extends from an outer, flat surface of the cap so that the spike structure can be inserted into the soil until the outer, flat surface of the cap is engaged with the upper surface of the soil. The spike and the flat surface of the cap thus hold the bottle in a stable, upright position. A wick extends through an opening in the cap. The wick has an inner end immersed in the liquid within the bottle and has an outer end which is inserted into the soil. The inner and outer ends of the wick are preferably cut to a tapered figuration for opening the pore structure of the wick and for permitting, at the outer end of the wick, a controlled transfer of fluid from the wick to the soil by capillary action.
