There are 2 tree pits on the south west corner of west 26 street and 9th Avenue right across from PS 33 that are empty. The tree stumps are there, and there are no trees. They are on the side of the Heywood building (old printing building), 263 Ninth Avenue, NY 10001.
This is the link to the tree request form. I filled it out and submitted it. The more the better. Please fill it out. I heard that the city does honor these requests. Thank you.
