The Green Pathway to Invasion: Ornamental Invasive Plants- Feb 27 at 1:30 pm and March 1 at 6:30 pm

Many of our worst invasive plants actually started as ornamental plants. Join Chris Evans, Forestry Extension and Research Specialist, as he explores why some plants end up becoming invasive, discusses some invaders that are still in the ornamental trade, and gives recommendations on how landowners can influence the surrounding natural landscapes through their planning decisions.

Tree Care in Urban Soils: March 13 at 1:30 pm and March 15 at 6:30 pm

Extension Horticulture Educator, Ryan Pankau will discuss tree care and urban soils by exploring the attributes of urban soils in contrast to undisturbed forest soils. Many common impacts to tree health can be related back to the level of disturbance in our urban soils. Ryan will discuss practical ways to diagnose tree symptoms related to soil issues and current tree care techniques that address soils.
