Meet up with representatives of the RSPB, the country’s largest nature conservation charity, and discover how Knoll’s naturalistic gardening ethos continues to create a garden that welcomes wildlife as well as providing year-round beauty. On this special day RSPB members and volunteers can visit the gardens free of charge on production of a valid RSPB membership card or proof of volunteering status. On this special day for every full price ticket purchased £5 will be donated to the garden’s charity, the Knoll Gardens Foundation.
