A bracket assembly adapted to be removably coupled to a railing at a first side and hold a portion of a container at a second side can comprise a lower section and an upper section removably coupled to the lower section. The upper section can be a bent strip that forms a receptacle to receive the portion of the container, and the lower section can include a body in the form of a second bent strip, and a fixed connection post extending from an upper surface of the body to interface with an opening in the connection interface of the upper section to removably couple the upper section to the lower section via the at least one fastener. The platform section can include a first step and a second step each extending from the connection interface to respective ones of the retaining arms.
