An RHS representative said: "In 2014, the RHS shows at Chelsea, Hampton and Tatton continued to be Britain's most popular gardening events. They attracted hundreds of thousands of visitors and significant media attention, with broadcast coverage of the shows reaching millions of viewers."
In 2014, the number of visitors to Chelsea remained static at 165,000 with the show sold out. Hampton Court Palace's attendance of 142,022 was its second highest since 2009. In 2013, the event attracted 154,034 visitors, up from 123,855 in 2012. At Tatton Park, there were 67,033 visitors, which was down from 72,845 in 2013 but similar to the total in 2012.
Some exhibitors criticised high ticket prices, while others said show layouts need re-examining, or that there are too many on the calendar.
The renamed Malvern Spring Festival attracted 87,000 visitors over four days (8-11 May), compared with 86,000 in 2013.
There were 92,000 visitors to Gardeners' World Live over four days in June, down from 103,000 in 2013 when the show ran for five days.
Harrogate Spring Show attracted some 58,000 people - a rise of about six per cent on 2013.
TV viewing figures were up for all RHS shows. Tatton Park attracted 1.07 million-1.26 million viewers on BBC2, compared with between 1.18 million and 1.27 million in 2013.
Hampton Court posted viewing figures of between 1.67 million and 2.01 million, compared with 0.85 million-1.56 million in 2013, in slightly different time slots.
Viewing figures for Chelsea were up for much of the BBC's 12-hour coverage, despite Alan Titchmarsh being replaced as lead presenter by Monty Don.
