The 60-gallon solution: Inoculating a giant elm is an all-day affair

It takes a lot of medication to treat a big tree. Aaron Gilmore and Gary Schakelman, tree specialists with the UW grounds department, spent all of Monday injecting the massive American elm just west of Ag Hall with some 60 gallons of a treatment developed to protect against Dutch elm disease.

It’s worth the effort. The Ag Hall elm is the largest of the fewer than 30 American elms remaining on campus.
