The options for scheduling Circle of Trees are many. It can be used on Sunday mornings as a multigenerational program sandwiched between larger segments of the congregation's religious education year. It can be used on Saturday afternoons or early weekend evenings, perhaps combined with a potluck meal. It can be adapted for use primarily with children and youth of mixed ages. It can be part of or central to a congregational summer program. It can be part of a weekend retreat. Consult with your religious educator or Religious Education Committee to schedule Circle of Trees.
Most Unitarian Universalists wish to provide stewardship to the world, and most are concerned about the earth and its resources—but prospective participants will only know about Circle of Trees if you tell them. Schedule the program when they are most likely to be free, and let them know well in advance of its purposes and merits.
