Bartlett Tree Research Laboratories

Happy fall to all and Thanksgiving to those who celebrate! 🍂🍁🍂

The azaleas on “rhodie hill” are in full bloom at the arboretum!

Under the microscope at the lab- early-season powdery mildew on crabapple. The infection has caused wilting of the tender new shoots and the fungus is forming textbook-perfect spore chains on the infected tissue.

We take pruning seriously at Bartlett, both on client properties and at the arboretum. Research Lab director Dr. Kelby Fite is reviewing the pruning specs for this feature laurel oak outside the lab buildings with a group of arboretum and lab staff in preparation for pruning today. 🍃🌳🍃
