Not to get long winded about it... You need SHARP trimmers. You need to go over the boxwood multiple times and shake your hand in it a couple times. And you cannot rush- float the trimmer over the shrub with your arms. If your legs, back and arms do not hurt when you finish 20-30 of them, you are doing it wrong. And yes, I was thinking today bout a different rate for straight trimming. It's worth it. And thank you guys for the compliments!
