Specialists from Civic Trees installed the trees across the streets, parks and residential areas of the London Borough of Southwark
They will also undertake ongoing maintenance.
The RE:LEAF initiative aims to encourage the planting of more trees across London, while also protecting the city’s woodlands and wildlife.
So far around 10,000 trees have been planted, with a further 10,000 promised during the course of Boris Johnson’s second term in office.
Civic Trees sales director Deric Newman said: "Urban locations can often present many challenges when it comes to tree planting and our experienced teams overcame them through good preparation and planning to complete this project successfully.
"The RE:LEAF scheme really benefits the whole of London as it not only improves the visual aesthetics of the city, but also offers its residents the chance to learn about and understand the growing process, while recognising the importance of trees in modern day society."
