Visit Opening times When are you open? The house and garden is usually open between April and November. Owing to the Coronavirus outbreak, in 2020 we implemented an advance booking system, to enable visitors to maintain safe social distance. The bookings system is likely to be in operation in 2021. Please check the website before you visit. The Garden is now closed to visitors until spring 2021. The Nursery and Shop remain open to visitors and mail order.
