Tree Root Collar Disorders | November 30

A root collar is an important area of a tree where root tissue shifts to trunk tissue. Impacts to this part of the tree can have a variety of symptoms from yellow foliage and early fall color to dieback in the upper canopy, and even tree death. Horticulture Educator Ryan Pankau will explore how to prevent, identify, and treat common tree root collar disorders.

Our Fall Four Seasons Webinar Series will inspire you to take action in your garden.

As fall approaches, trees begin to change color, cold weather sweeps in, and garden prepping for winter begins. Learn the best ways to care for your gardening equipment, identity native and non-native tree species, and recognize root collar disease before it’s too late.

Online registration is required. If reasonable accommodation is needed to participate, or for more information, contact Gemini Bhalsod at gbhalsod@illinois.edu. Early requests are strongly encouraged to allow sufficient time for meeting access needs.
