She will unveil a new plaque to commemorate the new-look landscape, first created in 1977 to celebrate silver jubilee but renewed to mark the diamond jubilee.
"It is particularly fitting that, 35 years on, the Queen returns to open the new Jubilee Gardens in this year of her diamond jubilee," said a spokeswoman for the gardens, designed by West 8 and built by Frosts Landscape Construction.
A month ago a second phase of work included 25 new trees, adding to the 69 mature trees planted in May. Flowerbeds were extended more than half to nearly 600sq m and a dozen benches made from iroko wood went beside existing granite seats.
This followed initial work such as paths, play area and gently sloping turfed mounds, which reopened in time for the Queen’s jubilee celebrations. Visitors topped the million mark last month.
A team dedicated to the park is maintaining turf and removing litter and is managed by a partnership of neighbouring landowners, local business and community organisations, called Jubilee Gardens Trust, which was set up to lead the transformation.
