“San Diegans can get a new tree, free of charge – all you have to do is identify a space in the public right-of-way that could benefit from a new tree and fill out and submit the form below. City horticulturists will evaluate the space and determine an appropriate tree selection.
Once the free tree(s) are planted, we ask that you help the City Water the tree for three years during the tree(s) establishment period.”
