How do I prevent winter burn in boxwoods? #854972
Asked November 08, 2023, 6:55 PM EST
I planted three young boxwoods last year in a place that gets morning sun. This spring they were heavily “yellowed”. The nursery told me they probably got “winter burn”. I think they have recovered this summer but I want to prevent the winter burn again this winter. A friend told me to wrap them in burlap for the winter. Is this a good idea? Have you a better idea?

Hello,
Boxwoods are unfortunately prone to winter burn. Wrapping them with burlap after a hard frost (which we have already had) can definitely help.
Also add a winter layer of mulch (up to 2-3”) to help keep moisture at the roots. Becareful not to cover the base stem of the shrub.
You could also consider using an anti-desiccant (you can buy at a garden center or online) to protect boxwoods from drying out in the winter wind. Apply before temperatures are reliably below 40 degrees.
