Brookfield Zoo will host its annual Tree Trim Saturdays and Sundays, Nov. 14-15 and 21-22, from 10 a.m. to 4:30 p.m., to allow for social distancing.

Brookfield Zoo’s Tree Trim has become a tradition for a variety of organizations including Scouts troops, schools, churches, libraries and clubs as well as individual families. Community Tree Trim participants receive a fully LED-lit tree, 20 complimentary general admission passes and five parking passes good on Tree Trim days only, and a sign featuring the town and the names of those who donated and decorated the tree. Trees purchased online with a credit card by Oct. 2 are $140. The price increases by $20 after that.

Companies can sponsor a corporate tree that is prominently displayed around Roosevelt Fountain. The cost is $500 and includes 30 admission passes and 10 parking passes good on Tree Trim days only, a fully LED-lit tree, and a sign featuring the company’s name and/or logo and a holiday message.

Both community groups and companies may purchase additional admission tickets at a discounted rate of $10 each. They are valid for adults, seniors, and children and are good only on Nov. 14, 15, 21, and 22. Additional parking passes are $15 each. Discounted tickets are available online through Nov, 22.

Due to COVID-19, this year, participants will be prompted when making reservations online to select what day they would like to decorate as well as what time their group will be coming to the zoo.

While the trees provided will be covered in twinkling LED lights, participants are responsible for decorating their trees with either homemade or store-bought ornaments. Ornament makers should keep in mind that decorations will need to withstand Chicago’s wintry weather. The zoo recommends that ornaments be painted, varnished, shellacked or laminated. Water-soluble glue is not recommended.

Participants should be mindful of the animals at the zoo when making ornaments. Use animal-safe items including Popsicle sticks, laminated paper, Styrofoam balls, plastic needlepoint, strung beads, soda cans, wood items or plastic containers. Do not use food items, sharp objects, straws, glass/breakable materials or tinsel. Hang ornaments with string or yarn.

A complete list of guidelines and creative ideas is available on the zoo’s website.

Trees are available on a first-come, first-served basis.
