Grounds contractor Turf Soil worked with local volunteers, schools and Greenwich Park Friends on the orchard, which boasts plums, peaches and apricots, with a heritage dating back to the 1500s. It is managed by the Royal Parks.
Last year, pathways were restored, raised planters were installed and teams worked on two ponds. Volunteers grew flowers and vegetables while artist Heather Burrell and pupils of John Roan Secondary and Meridian Primary Schools designed a decorative metal gate and a well covering.
Greenwich Park manager Graham Dear said: "The Queen's Orchard has never looked so good."
