a location above level 38 of soil 14 the outlet of conduit 36 may include a nozzle 40 to provide a spray of water depicted by numeral 42 alternatively the nozzle may be of the type providing drip irrigation to reduce losses due to evaporation common with sprays the discharged water whether by spray or drip provides the necessary water for plant 16 it is anticipated that nutrients may be dissolved in the water in the container to assist and promote plant growth electrical power for the pump and its attached electric motor is provided by a battery 50 through electrical conductors 52 a timer 54 is employed to regulate both the duration and frequency of electrical power provided to pump 30 thereby the quantity and frequency of water discharged through nozzle 40 may be preset commensurate with the requirements of plant 16 and considerations of weather after a period of time all of water 55 within container 12 will have been consumed or nearly so a tube 56 is in fluid communication with the interior of container 12 and extends upwardly preferably above level 38 to provide access to inlet 58 of tube 56 as depicted by arrow 60 water may be injected through inlet 58 to fill container 12 necessarily the battery will have to be either replaced or recharged from time to time.
