An Urban Tree Care Conference

Think Tree Resources


Trees that have stood the test of time and show some battle scars, dead branches, and other signs of aging are often referred to as veterans. On a once-beautiful tree, these signs might suggest a 'mortality spiral' to tree owners, and to arborists.

They speak to the soil through chemical interactions, electrical pulses, and water, nutrient and gas exchange.
