What is the consequence of burying the root flare during planting?

• A. Improved root establishment
• B. Increased trunk buttress growth
• C. Reduced soil aeration
• D. Girdling roots and poor establishment

Answer: (D)

Burying the root flare places the trunk’s transition zone below the soil surface, which disrupts how the tree forms its root collar and absorbs oxygen. When the flare is buried, roots can begin to grow from the trunk into the surrounding soil and may start circling the trunk as they increase in number, eventually constricting the trunk in a process called girdling. This interferes with water and nutrient flow and weakens the tree’s ability to establish a healthy, widespread root system. The result is poor establishment, and over time the tree is more prone to stress and decline. While reduced soil aeration can also occur with burial, the most direct and significant consequence is girdling roots along with poor establishment.
