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? If so, anyone know of someone in north DFW (I'm in McKinney)?

Call an arborist who knows what they're doing. You have to remove quite a bit you get the mistletoe completely out because it basically roots into the tree. Your options come to removing entire affected branches, or removing the mistletoe and surrounding bark, then wrapping the area to cut off sunlight to any remaining mistletoe.

Well... it depends how much mistletoe - but mostly mistletoe isn't good for a tree. Mistletoe seems to like Cedar elms and you notice it when the leaves fall. If it's just a few limbs high up - no big deal. If the mistletoe is so dense that it's effecting the tree's ability to grow leaves, or you see it in a major limb and the mistletoe has caused deformity in the limb, then you might want professional help as suggested above.

You can just cut the mistletoe with a long-arm saw to slow it down, but it will come back. I generally just cut it out to slow it down. But again if it's bad - then call somebody who specializes in this.

Ha ha....thanks for the info guys!
