How to Insulate Potted Trees

Wrap each tree pot with three to four layers of bubble wrap, available from the post office or office supply store. Cut off the excess bubble wrap using scissors and then secure the end firmly with two to three pieces of duct tape.

Move all of the potted trees to a protected location near the side of a home to prevent wind and snow damage. Place the pots as close together as possible, with the rims touching each other.

Water the soil in the top of each pot well before adding insulation to ensure the roots are hydrated enough to survive the winter.

Spread clean straw or leaves over the ground under the pots and mound it up until the pots are no longer visible. Then add more straw on the top of the trees at least half way up the trunks. When applying the straw, do not pack it down. Instead, pull it apart with your hands as you spread it to create air gaps, which increase the insulation properties.

Insert a round tomato cage over the tree and push the prongs down into the pot. Wrap burlap around the cage until it is completely covered and staple it to itself using a stapler. This both insulates the tree and prevents heavy snow from breaking the branches.
