The Learning Garden is a productive educational garden that will be developed in a green field in Beaulieu village.
Managing director Patrick Fairweather said the aim was to promote the freshness, taste and sustainability of vegetable growing. The garden will feature water recycling and conservation, and sustainable gardening practices.
He added: "We aim to teach children about growing healthy, wholesome food, as well as the value of composting and how to identify insects and other creatures that contribute to the garden ecosystem."
The vegetables grown will be integrated into dishes made at the garden centre's cafe as well as supplied to school kitchens.
A head gardener is to be employed to manage the project.
