2019-2020 Contest

Show us your students’ creativity by re-purposing milk and juice cartons from your school cafeteria to either build or enhance your school garden. Educators can engage students in a hands-on experience creating teachable moments on environmental stewardship, sustainable packaging and healthy living.

The best use of cartons in a school garden gives your school the chance to win one of 15 prizes with a grand prize valued at $5,000.

We can’t wait to see your students’ creations—carton planters, garden art, scarecrows, window boxes, irrigation systems… The more creative, the better!

Important dates:
  • Beginning of School > Start collecting your cartons
  • Tues., Dec. 1, 2020 > Entries due
  • Fri., Jan. 8, 2021 > Winners announced


Get started on the right foot. Assign a classroom, teacher, or student team to be in charge of the project and start gathering cartons (suggestions: an art class, a home room, etc.). Have students draw up sketches of their ideas, then vote as a group on which one to make. Collect at least 100 cartons to use in your garden creation. Then gather materials, assign tasks, make it, nurture it and enjoy a growing learning experience together!

To help you get ready to submit your entry, Entry Form Checklist lets you know what questions you should be prepared to answer on the entry form. You can submit up to 10 photos of your creation. To be eligible for the grand prize or a specialty prize, in addition to the entry form and photographs, submissions must also include a video link to represent their project. Video should be under 5 minutes.
