Moving plants at this time of year may seem difficult but can be done. Dig up the yew, keeping as much of the root ball as possible. Lie it down in a protected area, and cover the root with whatever you have available--leaves, loose soil, and cover with a couple of layers of burlap. It is important to keep the root ball moist while it is out of the ground and keep it from freezing. It would be better to return it to the ground later in the spring, when the soil has settled.
