Wrapping palms instead of boxing zone 5

[ChicagoPalma]

I have found a Facebook post of someone in Milwaukee protecting his large trachycarpus with just wrapping it in burlap, lights, and an insulating tarp. Nothing more. Do you guys think I might be able to do the same as one of my palms is outgrowing its winter box every year. A somewhat large trachycarpus, around 15-20gallon sized palm.

IMHO, z5 is too far a stretch. I would box it.

1. Use a post-hole shovel and dig four 4-inch holes to form a 4-foot square. Dig about a foot deep.

2. Go buy a 4-foot piece of 4-inch PVC and cut into four 12-inch sections. 

3. Tap one section of PVC into each hole.

4. Come November, you should be able to set a 2x4 into each corner. 

5. Attach wall material to both the inside & outside surfaces of the 2x4s.

You can figure out the rest.
