Is it too late to trim a boxwood hedge in zone 5?
A. A double whammy, but the same concern…spreading boxwoods. At least the plants are growing well and you are not writing me to find out why they are dying! Trim the shrubs now that the temps have risen and spring is upon us. I prefer to have them pruned either in the fall right before dormancy or in the very early spring before any new growth has appeared. I just returned from Ohio and saw that they are sprouting, so prune immediately. Go through and shape them as desired. Feel free to trim way back. Take out 6 inches or as much as 2 feet I would say. The new growth will fill out and grow out better if you trim to good hardy strong stems. Clip out any weak stems and dead branches to give more light to the healthy ones! The more that you trim out the old and weak, the better the new growth will be, and before July I would think you would not even notice any old holes. For future notes though, I would like to have you prune yearly, a little at a time, rather than once in a while takin
