I’d like to thank everyone who works on our breathtaking horticulture, diverse events programme, garden-inspired catering and fantastic shops and plant centres. It is the hard work, passion and dedication of this team of people that makes a day out at an RHS Garden such an unforgettable experience and has helped us to have our busiest year ever."
