Support Korean Boxwood during super cold #923878

Asked January 22, 2026, 4:52 PM EST

Hi, I have a 30 year old korean boxwood, a family heirloom, that was transplanted a few years ago into my garden. After last winter, with the freezing, melting and refreezing it suffered a bunch of damage. However, with your advice, it did perk up over the growing season and started growing new branches/leaves. I'm worried this super cold is going to kill it. I am leaving town for a week starting Saturday. How do I protect it? Will burlap cloth be enough? Attached is a photo of it healthy from Oct 24, Aug 25 and today. Thanks for the advice! Caitlin

Hi Caitlin,

You could wrap it in burlap, making sure to remove it when temperatures warm.

The best protection from winter damage is to keep the plant watered well right up until the ground freezes.

Good luck. These are challenging conditions for an already stressed plant.
