Try to make sure the trees have enough ground moisture before the ground
freezes.

1. Boxwoods , about 2 ft tall

Yews? Hardy. My neighbor has 'em.

3. Hot Cocoa Roses , about 4 to 5 ft tall

Burlap needed. Or you could trench them, but I dislike cutting roots.

If the roses are a grafted variety, you definately need to protect the
plant above the graft or it will come back from the roots and you don't
know what will come up.
