The inner south London borough planted 500 street trees this winter and last, and plans a further 200 next winter, in addition to planting on housing estates and in parks.
Species include London plane, cherry, lime, pear, crab apple, rowan, oak, hazel, whitebeam, maple, hornbeam and birch.
The council’s cabinet member for parks and open spaces Cllr Steffi Sutters said: "We are determined to be one of inner London’s leafiest boroughs, and the tree planting programme we have carried out over the last two winters is one of our biggest ever."
She added: "It truly is a magnificent sight to see them come into blossom, and I’d like to thank everyone who helped us look after the young saplings during last summer’s heatwave."
Wandsworth was one of the first urban councils in the country to establish a network of tree wardens, who work with the council to monitor the health and well-being of trees in their neighbourhood.
In total the council looks after more than 60,000 trees in its parks, commons and open spaces, while around 16,000 grow in residential streets and on the borough’s housing estates.
