If your arborvitae branches are drooping in the winter, it’s likely due to dry soil, heavy snow, strong winds, or all of the above. There are a few things you can do to prevent this.
Apply a thick layer of mulch around the base of your plants to insulate the roots and keep the soil moist. If your plant dries out, it will droop and turn brown.
Gently knock heavy snow off the branches of your plants.
Plant your arborvitae in an area protected from strong winds (like on the side of your home or shed).
Wrap your plants with burlap or tree wrap for winter protection.
