Published annually in spring, 'The Garden Visitor's Handbook' lists nearly 4,000 gardens open for visiting. It is packed with full-colour photographs and informed comment. Fully updated and supported by an online database, it is now easier to use than ever. Look out for sensory gardens, those offering accommodation and delicious treats, and learn how to create your own patch. Find a garden to visit near you and support the NGS's vital charity work.
