How trees support each other and us on National Tree Day

Trees share more than just space

At Southern Metropolitan Cemeteries Trust (SMCT), trees are more than just part of the landscape. They offer shade, beauty, and a quiet place to reflect. But did you know that trees also support one another, just like we do in times of grief?

Recent scientific discoveriesExternal site have revealed that trees of the same species growing close together can fuse their roots and share nutrients. In 2016, botanist Tamir Klein and his team at the University of Basel found that trees sprayed with carbon dioxide passed it on to neighbouring trees. This suggests a collaborative underground network.

This network is powered by mycorrhizal fungi, which connect tree roots and help transfer water, minerals, and nutrients between trees. When one tree is struggling, others nearby can offer support. It’s a natural example of community care.

“Neighbouring trees interact in complex ways. They form communities, or ‘guilds,’ where individual trees share valuable resources. Trees in a guild usually thrive more than those that don’t.”Botanist Tamir Klein, University of Basel

A symbol of support in times of grief

On National Tree Day, we celebrate this natural show of care and connection. Trees remind us of the importance of community, especially during times of loss. Just as trees support each other underground, our family, friends, and community offer emotional and practical support when we’re grieving.

Whether it’s a warm meal, a comforting hug, or simply being present, these acts of kindness help us stay strong.

Trees at SMCT: a living tribute

Across SMCT’s memorial parks and cemeteries, trees play a vital role in creating peaceful, reflective spaces. From towering gums to flowering natives, our diverse tree species offer shade for visitors and a serene resting place for loved ones.

They also serve as a living tribute, a symbol of resilience, connection, and care.

Who has been a tree for you?

This National Tree Day, take a moment to reflect:
🌳 Who has supported you when you needed it most?
🌳 Who could use your support right now?

Share this story with someone who’s been your tree, or someone who might need one.
