Bare root trees are $45 per tree, while balled-and-burlapped varieties are $65 each. All trees are one inch in caliper and 5-9 feet tall, depending on variety.

The Denver Digs Trees program is responsible for adding more than 30,000 public trees to Denver's streets, with hundreds more sold each spring to help raise funds for the non-profit group's public tree efforts. More than 300 volunteers make this effort possible.

The springtime celebration continues on Saturday, April 26 with a large-scale tree planting effort in Sunnyside in northwest Denver. Hundreds of community volunteers, including those from Volunteers for Outdoor Colorado, will plant several hundred trees to enhance the urban forest and beautify this underserved neighborhood. The Denver Housing Authority's Quiqq Newton Homes site will benefit from the addition of 300 trees from this special community effort.

"Increasing the tree coverage in our city not only helps the environment and beautifies our neighborhoods, it also inspires neighborhood connections," says Patrick Hayes, executive director of The Park People. "Our efforts have proven to strengthen ties between neighbors, and, every year, we pick a neighborhood we feel will be greatly impacted by our tree planting efforts."

Program supporters include Denver Housing and Neighborhood Development Services, Xcel Energy Foundation, Esurance, The Home Depot Foundation, Alliance for Community Trees, Colorado Garden and Home Show, Colorado Tree Coalition, and Plant-It 2020. The Denver Digs Trees program is a collaboration of The Park People and Denver Forestry Department.
