Visits to Wisley have grown over the past 10 years from 734,000 to more than one million a year. On its busiest days, up to 10,000 people pass through the doors. The improved visitor entrance will include an exhibition space.
The RHS is also planning a space for specialist UK nurseries. The Wisley shop will continue to stock garden sundries, horticultural books and gifts, alongside a new cafe and restaurant facilities as well as a plant centre.
