Abstract: A lawn fertilizing device for installing in a water system. A chemical substrate that is to be applied to vegetation is disposed in an enclosed container. The enclosed container has a plurality of apertures disposed on the container walls to allow water to flow through the container and contact the chemical substrate. The container is placed on a base and covered by a housing. The housing is secured to the base via a screw cap threaded to a base wall.

Abstract: The present invention features a fertilizing device for installing in a water system comprising a top cover removably and sealably attached to a base; an intake pipe disposed on a first side and an outlet pipe disposed on a second side of the base, the intake pipe and outlet pipe are both fluidly connected to the inner cavity of the top cover; an open container with apertures disposed in the first and second container side walls for holding a fertilizer bar; wherein the intake pipe is connected to a first portion of a pipe of the water system, the outlet pipe is connected to a second portion of the pipe of the water system; wherein water from the water system can enter the intake pipe, mix with the fertilizer bar, and exit via the outlet pipe.
