I was out watering and weeding the mulched area of my 2 newly planted October Glory maples (guess they are about 4 years old cause they are about 3 caliper) this evening when I came upon a thick white root coming through the mulch. Thinking it a weed, I gently pulled but the root did not come out, so I snipped it with scissors. Now I'm wondering if I should have done that. I shouldn't be seeing roots coming out of the mulch from the tree should I, or is this normal growth from the tree that I should leave alone? The trees were b&b, not bare root.
