If your school or neighborhood already maintains a garden, it could pick up a compost bin through a city contest.

The city’s Environmental Services Department will award two bins to the top vote getters on the Do More Blue Tucson Contest on its Facebook page and two more through a random drawing among contest entries.

"Composting is a great way to preserve our resources while reducing greenhouse gas emissions,” said Francis LaSala, waste diversion manager in a press release. “Composting is relatively simple, and reduces a garden's need for soil amendments. This contest is a great opportunity for students and the community to practice the three R's of waste diversion: Reduce, Reuse and Recycle."

To enter, go to Facebook.com/DoMoreBlueTucson and “like” the page. From there, they can then click on the contest tab, fill out an entry form and submit a photo of the garden.

Photos will be displayed until February 14.

Once the votes are tallied, Environmental Services will deliver the bins to the winners. In addition, they will also receive some type of recognition from Mayor Jonathan Rothschild.
