National Tree Week is the biggest annual tree celebration in the UK. Every winter, The Tree Council rallies people across Britain to plant over a million trees. Healthy trees mean healthy communities, and planting together helps us all grow stronger.

When did National Tree Week begin?

The campaign began in 1975 as a response to the Dutch Elm Disease outbreak in the 1960s, which wiped out millions of trees. The UK responded with the “Plant a Tree in ‘73” initiative. Its success led to the founding of The Tree Council, and the first National Tree Week followed two years later.

What happens during the campaign?

Now in its 50th year, the campaign faces a new challenge with Ash Dieback. To protect our landscapes, we must keep planting trees in parks, streets, woods, and green spaces.

National Tree Week features planting events and workshops nationwide. Schools, local groups, Tree Council members, and Tree Wardens organise activities. Visit The Tree Council’s interactive ‘Near You’ map for local events. The website also offers event tips and downloadable posters.

“With forty years of successful growth behind it, National Tree Week has become firmly rooted in the calendar of hundreds of community groups around the UK,” said Pauline Buchanan Black, Director-General of The Tree Council. “To mark the 40th anniversary of this important campaign, we want to celebrate Britain’s rich heritage of tree-planting and applaud the commitment of communities that really value their trees.”
