"We aim to increase the number of trees and ensure the 40,000 currently managed by the council are well protected and well managed," said a representative.
Regular tree inspections will be backed up by an investigation on whether or not new fruit trees could be planted for food sources around schools and at allotments.
Haringey will also set up a community tree nursery, with school visits to teach children the benefits of trees.
"Trees improve the look of our streets, open spaces and housing estates, and they improve air quality and attract wildlife to the borough," said councillor Dhiren Basu.
