Funding garden maintenance and tree care

By becoming a member of the Arboretum Foundation or making a donation, you play a vital role in preserving and enhancing the Washington Park Arboretum for current and future generations. The Foundation supports the maintenance of the Arboretum’s plant collections, gardens, and natural areas in the following key ways.

  • Funding the UW Botanic Gardens staff arborists, who keep the Arboretum’s woody plant collections healthy, safe, and vigorous.
  • Funding the salaries and benefits of the two UW Botanic Gardens horticulturists who care for the Pacific Connections Garden in the Arboretum.
  • Funding temporary gardeners assigned to special projects, such as the restoration of the Lake Washington Boulevard Corridor.
  • Coordinating the Garden Stewards program, which recruits and trains volunteers to assist horticulture staff with weeding, mulching, and other tasks.
  • Coordinating the Corporate and Group Service Program, which recruits volunteers from local businesses and community groups to participate in weeding and mulching work parties.
