Root Flare Exposure and Tree Health
Root Flare Exposure and Tree Health Root flare exposure is critical to a tree’s health. However, people often plant trees too deeply. Nearly eighty percent of trees in urban areas have had their root flares covered by dirt during planting. Others have had their flares covered up by mulch. A tree with its root flare exposed is less likely to have health problems. What is a Root Flare? Unlike the roots of a tree, the root flare has bark. The main function of bark is to protect. Bark protects the living tissue, known as the cambium, from damage. It acts like a shield, keeping disease and pests from its critical parts. Plants contain aerial tissue called bark that is designed to be exposed to air.
