I have a tree in my front yard that appears to have spots of mistletoe in multiple locations, some way higher than I could get to. It's very apparent now, with the leaves gone, and I do not recall seeing it this time last year. My understanding is that it can eventually damage or even kill the tree if left unchecked. Is that right? I am assuming an arborist would be the best person to call? Anyone know of someone that services McKinney?
