Root Collar Exposure

In other words, if a tree’s trunk does not have a flare where it meets the ground, it was likely planted too deeply in the first place. Because root collars should be unburied, exposed to the air and exposed to the above-ground temperature, root collar exposure if vital to the health and longevity of the tree. There are effective remedies for trees lacking a root collar, and our team of ISA-certified arborists at Certified Arbor Care can help you.

Avoid covering the vulnerable root collar with dirt, soils and even mulch. It is important to see the root collar and the primary roots on a properly planted and mulched tree. Our team of ISA-certified arborists at Certified Arbor Care can offer care to a tree with insufficient root collar exposure. We are trained to safely and effectively remove mulch, soil and dirt from beneath the trunk of a tree to properly expose the root collar. We carefully remove topsoils, rocks and debris from a buried root collar to expose it to the air. We use special care as to not disturb or damage the root structure. After the root collar is exposed, we properly apply mulch, but keep it away from the trunk and exposed root collar and spread it out to a diameter of about three feet or more and to a depth of about four inches.
