Answer: Boxwoods are typically pruned in the spring and the technique depends upon whether you want a specific shape or you simply want to keep the plant from overgrowing its position in the garden. Boxwoods are easy to prune - hedge trimmers can round them out or square them up and they are generally used for boxwood hedges. You can use hedge trimmers to remove a couple of inches of growth each year to keep your boxwoods neat and tidy. More radical pruning, again with hedge trimmers, can be done to renovate an overgrown boxwood, this time taking up to one-third of the material off the shrub.
