Designer Simon Fagg, who was not awarded a medal for the garden, said: "A massive thank you to everyone who helped out getting all this built, against the odds as it felt at times...What an incredible journey the last few weeks have been!"
The Sheffield Wildlife Trust Living with Nature Co-ordinator thanked suppliers including Pentland Plants, Wykeham, Long Rake Spar, Lindum and garden sponsor KBI (UK) for their help. Appleyard Landscape was the contractor.
An RHS representative said: "The garden was judged against the usual criteria and unfortunately failed to make the standard required for a medal. However, we don't discuss details or reasons for awards, except with individual exhibitors."
