During the Second World War the NSW government asked residents throughout the state to consider growing their own vegetables. Mosman Council supported this notion and sponsored a working group under the direction of its own head gardener to teach locals how to grow vegetables in their gardens.

Calling themselves The Mosman Agricultural Society, this group established the Mosman Home Gardeners’ Association after the war and went through several names changes over the decades finally becomingThe Mosman Home Gardeners’ Society Inc.

The Society fosters an interest in gardens, with regular outings and meetings where members share their knowledge and until recently the Society’s Annual Spring Show was a popular event on the local social calendar.
