Trees x 10

“Trees x 10” is a voluntary, community-based project facilitated by Nadja’s Garden.

What does it do? Tx10 supports gardeners to share their home tree-planting experience with friends, family and neighbours, so that our community can rapidly become skilled and switched on to grow more trees in every garden. It can turn your quiet planting morning into a lively little workshop, generating new connections, inspiration, learning and confidence.

Why? Adelaide has the least tree cover of any Australian capital, while also being the hottest and driest capital. Even while efforts are being made to green our streets and parks, these efforts are still being outpaced by the loss of canopy on private land, mostly due to infill housing development. And many residents in Australian cities lack confidence, knowledge and experience in selecting, planting and maintaining suitable trees for the garden spaces they have available. Trees x 10 aims to help community members share the information and the experience to reverse the loss of our urban forest.

What does “Trees x 10” mean? It means let’s….

  • Multiply the coverage of urban tree canopy rapidly
  • Diversify plantings, creating plant communities
  • Meet in small local groups (10 is very effective) to learn, plant and share
  • Spread the action quickly – from each planting event, attendees take ideas for planting – and maybe hosting! – in their own garden.

Who and Where? Anyone with a garden (home or community) in Adelaide can host a planting event and invite their own guests. Contact Nadja at to express your interest.

Our climate is becoming hotter, drier, wilder, more erratic – and the trees we plant NOW are an essential part of both mitigating and adapting to climate chaos.
