Conservation and restoration of historic gardens

Several universities and colleges in England run undergraduate and postgraduate courses related to historic garden conservation.

Since 1995 it is a statutory consultee on proposals affecting registered parks, gardens and landscapes in England.

The society has an active group for Scotland, with its own regular newsletter and conservation officer.

A Historic Garden Week is run, in part to raise money for restorations.

Recent and ongoing examples of garden conservation and restoration in England include the Privy Garden at Hampton Court Palace, Painshill in Surrey, Lowther Castle in Cumbria, Lever Park in Lancashire, Biddulph Grange in Staffordshire, Kenilworth Castle in Warwickshire, Croome Court and Witley Court in Worcestershire,[11] Wrest Park in Bedfordshire, Westbury Court Garden in Gloucestershire, and the Lost Gardens of Heligan in Cornwall.

Biddulph Grange, Witley Court and Heligan are Victorian gardens (of rather different types), and Lever Park early 20th century.
