The first show is scheduled to start on 4 March.
The BBC said: "Main presenters for GW will be as in previous years – Monty Don, Joe Swift, Carol Klein and Rachel De Thame.
"They will be joined by guest presenters throughout the series but these are not confirmed as yet."
Meanwhile, a top job at the RHS is yet to be filled six months after the incumbent left.
The head of shows, garden and retail post, that David Morley took in 2014 before leaving in summer 2015, has been advertised and interviewed for, but six months on from Morley's departure, the RHS said they have no news on a successor.
