With Tree City USA - Arbor Day Foundation, gardening and planting trees will help Buda be more sustainable. Meanwhile, giving you landscaping knowledge and beautifying the city in which you live in. Tree City USA is a program that has been greening up towns and cities across the U.S. since 1976. Their mission is to create change through trees, as they give us clean air, water, and keep us healthy. For Buda, it provides a groundwork to manage and bolster our public trees.
