I was curious how to overwinter big evergreen bushes that will stay in big pots all winter?

I would mulch the top of the soil and wrap the base in burlap stuffed with straw or leaves. If possible, move the pots near a large structure like a house or a garage. This will keep it from getting too cold, and on the flip side, will keep it from thawing out during short periods of warm weather too, which can also be damaging.
