The free website, an offshoot of www.gardensandpeople.co.uk, will go live in March 2011. It will be a directory of gardens open to the public whose accessibility is written about by disabled people, their friends and carers.
The website is intended to be a reference for people planning visits - wheelchair or scooter users and people who have sight or hearing problems - and to see whether gardens' disability statements are good or need to be tweaked.
D'Arcy said gardens such as Bressingham Gardens had asked her for assessments, with regular problems including non-concrete ramps that end at paving stones or lawns that meet a solid surface and cannot be mounted by scooters.
She also appealed to Horticulture Week readers for either good or bad feedback on accessibility.
