The series was produced by Belfast based production company, Sixteen South and Sesame Workshop.
Martin P. Robinson assisted in auditioning and training local performers, who include Lesa Gillespie, Paul Currie, Michael McNulty, Mike Smith, Helen Sloan and Alana Kerr.
The initial series of Sesame Tree comprised twenty seventeen minute programmes, aimed at an audience of children aged 2–5.
Following a format similar to that of The Hoobs, it is composed of original puppet segments featuring Muppets created specifically for the series, local mini documentaries depicting a child's eye view of life in Northern Ireland, and classic Muppet segments from the library of Sesame Street.
The title and background music for the programme was composed by artist of Northern Ireland, Duke Special.
