It increases levels of alertness , socialisation  and social integration in care settings . It lessens the stress of residents moving into care , and increases a sense of personal control .
Gardening is shown to decrease the number of falls  and their severity of injury . It reduces blood pressure , improves grip strength  and fine motor skills , stimulates appetite , eases bed sores  and assists pain management .
Wider spiritual matters of later life can be addressed such as providing an opportunity to discuss issues in a non-threatening way , offering a gardening legacy  through the development of creativity and self-expression , whilst providing a connection with nature .
In older folk’s care settings, research shows that greening the environment both indoors and outdoors may benefit staff, relatives, visitors and care providers.
