Trees New York in Action
Trees New York Plants 361 Trees in the Bronx

Greening the Bronx

This fall, in partnership with the New York City Housing Authority (NYCHA) and the New York State Research and Development Authority (NYSERDA) TNY is planting 361 trees on the Mill Brook, Mitchell, Patterson, and Forest in the Bronx.  Bronx residents will now be able to enjoy a variety of trees including Tulip trees, Crabapples, Callery Pears, Lindens, Pin Oaks and Chinese Scholar trees.

Local volunteers will be trained to care for the newly planted trees. The trees will be studied to measure their environmental impact on the urban heat island effect, air pollution and energy usage.  If you would like to get involved and learn how to steward these newly planted trees, please email nelson@treesny.org

Autumn Tree Tip

Don’t forget to water your trees in the fall. Roots will continue to grow until the soil hits about 40 degrees fahrenheit and even as the leaves change color and fall, they are actively breaking down the compounds stored within the wood of the tree for next year. Lower temperatures mean that there is less demand on the tree for water, but we are also having less frequent rains than in the summer. Water at 2/3 to ½ the rate you would in the summer and help your tree finish off the year strong.
