Growing a Greener Future Together
National Tree Week, Ireland’s largest annual tree celebration, is proudly organised by the Tree Council of Ireland in partnership with Coillte. This special week invites communities nationwide to come together to appreciate the beauty and critical importance of Ireland’s trees. To support this initiative, Coillte is supplying sapling trees to County Councils for distribution to communities nationwide.
If you’re planning a National Tree Week community event and would like to receive trees for planting, please contact your local County Council for more details.
Annual Photography Competition
In celebration of National Tree Week 2026, the Tree Council of Ireland, supported by Coillte, is inviting primary schools across Ireland to take part in Coillte’s third National Schools Photography Competition.
The national competition encourages pupils to submit a photograph of their favourite tree or outdoor nature space, along with a short explanation of why it is meaningful to them.
Four winning schools, one from each province, will each win a class trip to Beyond the Trees Avondale in County Wicklow.
