The trees were intended to be planted on Arbor Day as an observation of the holiday, but COVID-19 delayed the planting several months. (U.S. Space Force photo by Griffin Swartzell)

The trees made that corner of base a little greener, as well as converting carbon dioxide into life-sustaining oxygen. (U.S. Space Force photo by Griffin Swartzell)

Though it’s unusual to plant in December, Kelley said the three evergreens should take root so long as the root balls don’t dry out. (U.S. Space Force photo by Griffin Swartzell)
