October 5, 1927. Opening to the public in 1929, the future was indeed bright for the Arboretum. With the crash of 1929, subsequent depression, a drought, and the passing of the Colonel in 1930, the Arboretum began to struggle. Dr. Crider left as Managing Director in 1934 and was succeeded by Frederick Gibson. The Picket Post House was sold in 1946 to help cut costs and raise revenues for the Arboretum. Frederick Gibson stayed as Director until his death in 1953. The Colonel's nephew, Joe E. Thompson Jr., became the Managing Director until the agreement with the University of Arizona in 1965.

Visitor Center, Demonstration Garden, and Legume Garden were completed under his tenure as was the planning for the
Children's Garden. Exhibits became more geographically focused and the word “conservation” was added to the mission statement. The Demonstration Garden was developed by Dr. Warren Jones from the University of Arizona and Steve Carter from the Arboretum. The Children's Garden was left for Dr. Mark Bierner to realize during his tenure from 2005 to 2008. In addition, the Picket Post House was purchased by Arizona State Parks in 2008 making the Arboretum whole again.
