A new fifth garden could also be announced by Alan Titchmarsh at an RHS 'vision' launch on 22 October in London. Birmingham Botanic Gardens say it is not in talks, but RHS executive vice president Jim Gardiner says he is looking for a garden between Bristol and Manchester and with the RHS pulling out of BBC Gardeners World Live in Birmingham, a West Midlands garden that is publicly or privately could be attractive for the RHS to take on. A site of around 40ha is likely to be near the M5/M6 and will be redeveloped to add shops and cafes.
One of the 10 RHS aims is a new science centre and knowledge bank at RHS Garden Wisley in the Hilltop area. A new visitor hub and welcome space for Wisley is also planned, as are craft units and more apprentice accommodation.
Another project is community outreach across the UK. There are pilots running in Scotland and Yorkshire.
A Learning Centre at RHS Garden Hyde Hall is planned.
RHS Lindley Library collections are to be opened up with new exhibition space.
The RHS also wants to bring horticulture to city communities through urban gardens, raise the profile of careers in horticulture through the Horticulture Matters campaign and develop the Harrogate Arms into a catering outlet at RHS Garden Harlow Carr.
Meanwhile, RHS Chelsea Flower Show is set to have a garden sponsored by Coutts by an unknown designer. Other gardens planned are Cleve West for M&G, while Andy Sturgeon will design for the Daily Telegraph.
Among other designs, the Rich Brothers have applied to return with Cloudy Bay after winning gold in 2015, while Hugo Bugg is set to return with Royal Bank of Canada. Jo Thompson is also set to design another show garden. James Basson is believed to be returning with L'Occitane. Final decisions on who has won a place at the show are being made in October.
