The Diggers Foundation is hosting a very special day at the historic Mueller Hall in Melbourne’s Royal Botanic Garden as we ‘speak for the trees’, encouraging gardeners to take personal responsibility for their carbon footprints by planting trees.

  • What happens below the soil? 
  • How to secure Australia's environmental future 
  • What every gardener can do to create changes needed

We speak or the trees

This book contains detailed information on almost 100 ornamental, fruit and nut trees selected for climate suitability, shade, habitat protection and bushfire prevention.

Each tree listed in this book is growing in one of The Diggers Foundation gardens, so we have gained valuable first-hand knowledge by planting, trialling and careful study over more than 40 years.
