Boxwood Trimming

Asked September 17, 2019, 4:08 PM EDT

Hello, I was wondering when the cutoff is for trimming boxwood in Minnesota in order for enough time to be allowed for the plants to safely harden off before the winter. Thank you for your advice! Luke

We do not recommend pruning evergreens after mid summer. Please note that boxwoods are only marginally hardy here, so pruning them late can make them more susceptible to winter injury. Read here:
