Tree Stewards help care for young trees on city-owned property. The 26-hour training begins with nine classes held on Monday nights. Once the in-class training is complete, volunteers attend three field sessions held on Saturday mornings during the spring. The in-field training focuses on tree planting, pruning, and tree identification. Once qualified, Roanoke Tree Stewards complete a minimum of 30 hours of work during their first year and 20 hours in subsequent years. Volunteers may also give educational presentations to adults and children.
