We have recently moved house and have a beautiful apple tree in our garden that is absolutely covered in mistletoe!
I've read that mistletoe is a parasite but is it draining the nutrients from the tree or just using it as a host to attach to?
How do I go about pruning/removing some of it as at the moment I can hardly see the apple tree for mistletoe? (and it might bring in some extra money at christmas!!)

Thanks in advance.
