Answer: Boxwood (Buxus) are generally considered to be shallow rooted plants and can be uprooted by digging in a wide circle around them and less than a foot deep; in fact, large boxwoods can be transplanted by this method so I am a bit surprised you were unable to dig them out. You might want to have another try at digging out the roots, but in addition you could try glyphosate according to the label instructions. You might have to allow the shrubs to resprout to some extent in order for there to be sufficient foliage to translocate the chemical to the roots where it actually works. Another alternative might be to find another gardener who would like to have the plants and would remove them for you -- since they grow so slowly this could be a case of one person's trash is another person's treasure.
