NGS garden visits make a difference to the lives of thousands of people across the UK

With record donations in 2024 the power of gardens and garden visits for good causes is evident. 2024 was another landmark year for the National Garden Scheme with the charity donating a record £3,501,227 from the 2024 garden opening season. The impact of these donations to our major nursing and health beneficiaries means that thousands of people who live with health conditions such as cancer or Parkinson’s, who have poor mental health, or who struggle financially as unpaid carers, have been supported by our funding of the nurses, health professionals and case workers who support them. Our funding has also provided support to those in the Gardens and Health sector along with Community Gardens and supported gardeners through traineeships. 

May is the month when The National Garden Scheme raises awareness of the physical and mental health benefits of gardens and gardening for everyone and of the importance of healthy gardens to wider biodiversity, through its dedicated Gardens and Heath Week, 3rd to 11th May.
