Possible girdling roots
Last Sept. I purchased and planted two 1.75 caliper autumn blaze maples. The trees were in containers. I had an arborist plant the trees. He told me he addressed the roots when he removed the trees from the containers.
I live in Northern Kentucky.
I was digging up the mulch around the trees today getting ready to put some new mulch down. I noticed a ring of roots about 10 inches from the trunk on both trees. I am very concerned about the long term health of the trees since this looks like a classic girdling root situation.
Any advice would be greatly appreciated. I'm wondering if I can somehow address the girdling roots and stop them from potantially damaging the trees.
