About us

Our history

Since 1993, we have grown into a thriving organisation with national and international impact, but we’ve stuck to our roots. Here are some of our milestones...


Four friends got together to set up Trees for Cities, or as we used to be known, Trees for London.


Three years after we were established, the volunteers and communities who had always made our work happen knew we were onto a good thing, and could do even more. So, we decided we were going to plant 20,000 trees in London by 2001…


An ambitious goal, but we met it a year early! Ready to keep going, we planted 10,000 more trees that year.


We hadn’t had enough, so we campaigned for 1 million more trees to be planted in London. Backed by patron Alistair McGowan, Suggs of Madness, Ali G and then Mayor of London, Boris Johnson, the campaign pushed for the trees to be planted by the opening of the 2012 Olympics. As reported in the Evening Standard, Mr G said: “Planting a million trees is wikkid.”


Our 10th anniversary! More trees were needed everywhere, we decided to expand our reach to the whole country, adopting the ‘Trees for Cities’ name and giving people up and down the country a chance to get stuck in with planting trees.

Ethiopia planting


We branched out even further, planting trees in cities across the world, including Addis Ababa, Ethiopia; Bucharest, Romania; and Nairobi, Kenya. In August 2004, we launched our first TV ad, ‘City Thumbprints’, which ran on Bloomberg and CNN.

Tree Athlon


We hosted (and invented the concept of) the first ever Tree-Athlon! Held in Battersea Park, London, it saw supporters run 5km, plant a tree and pledge a tree wish. Over 2,500 people took part on the day, and 1,000 ran the Tree-Athlon, making it a huge celebration of our urban trees.


Towards the end of the planting season, we reached a huge milestone – the planting of our 100,000th tree! An ornamental pear, the tree was planted by then Mayor of London, Boris Johnson, with a helping hand from pupils at Kings Avenue Primary School.


We celebrated our 15th birthday! Harking back to our roots, we held an extra-special club night and fundraiser. Nineteen Ninety Tree was held at Dex, Brixton (and yes, the pun was intentional). This wasn’t the only party we had, with “Get Twiggy With It” taking place in September.

Rotherfield Primary School


Edible Playgrounds was launched, with Rotherfield Primary School housing the first outdoor classroom, tailor-made for kids to learn about growing and eating healthy food.

The Great Trees of London book


We love our city trees, and London has some great ones. That’s why we worked with Time Out to publish a book that would shine a light on their unique histories. The Abbey Plane in Dean’s Yard, for instance, has swallowed up a piece of drain pipe that was lying on the ground, giving it a cosy, if slightly odd home.


In March 2011, The Dorchester Hotel on Park Lane, London, announced an ambitious plan to celebrate its 80th anniversary by planting 80 ‘Great Future Trees’ across the city.

Blue Trees


2013 was our 20th anniversary. Never a group of people to do things half-heartedly, we worked with Australian artist Konstantin Dimopoulos to colour trees in the heart of London bright blue. The art installation was part of the City of London Festival, and did what it was created to do: inspire Londoners to notice and reflect on the importance of our street trees.

Plant to the Beat


We hosted our first ever ‘Plant to the Beat’ event, supported by Festival Republic and Bloomberg. The concept was pretty simple: we got people together to plant 10,000 trees in Blondin Park, Ealing, while live music played in the background. Transforming green spaces and having a little dance? Sounds like a perfect day.

King George’s Field planting event.


Our work in Ealing grew further still, with a huge planting day in King George’s Field. We gathered together 580 people to plant 20,000 trees, making this one of our largest mass tree planting projects in London. It was delivered in partnership with Ealing Council, the Greater London Authority and Unilever as part of their ‘For the Love of Trees – London’ campaign. We were thrilled when the project won the ‘Community Woodland Creation Award’ at the prestigious London Tree and Woodland Awards in 2016.


We have worked with Bloomberg since 2002 to build sustainable livelihoods in East Africa, and in 2016 we helped communities in 5 countries plant a huge 31,887 trees. These projects engaged over 4,500 volunteers and local school children.


We launched #GenerationTree. Coinciding with National Tree Week, the campaign called on people to join the generation that plants more trees than it cuts down, by donating or signing up to volunteer with us.

Planting 1 million trees with Michael Palin outside St Thomas’ hospital, London


We turned 25! We knew we had to mark this big birthday in some very special ways. First of all, we planted our millionth tree with the help of Sir Michael Palin! During National Tree Week, we were thrilled to partner with the Mayor of London, Sadiq Khan, and plant a whopping 25,000 trees with nearly 900 volunteers in just one weekend, which made it London's largest planting event ever. You might also have noticed that we got a new logo and website - and we had our first ever flash mob at Kings Cross station.

St Paul's CE Primary School


With the backing of the Mayor of London’s office and our partner Bulb, we started a crowdfunding campaign to place a copy of ‘The Lost Words’ into the majority of London’s 2,500 state primary schools. And guess what – we did it! We’re hugely grateful to everyone who chipped in, helping to close the distance between children and the natural world. We also launched our Planting Healthy Air programme to help screen school playgrounds from air pollutants. Our first project was at St Paul’s CE Primary School in Hammersmith, ranked the second most polluted school in the capital.

Planting in small volunteer bubbles at Racecourse Estate


The global pandemic hit, and we had to put a pause on our mass tree planting events, although we were still able to work with small volunteer bubbles. To show our appreciation for the incredible efforts made by NHS key workers, we teamed up with Ecosia and NHS Forests on the #GrowYourLove initiative to plant trees around hospitals in the UK.
