Paramount’s Perfect Shrubs

Olivia noted to me after I showed her the photograph that these shrubs by no means looked perfect, but alas hear me out. Colin & Greg live very near Paramount Pictures, and every day I was in Los Angeles we either drove or walked by the studios. Ringing the perimeter is a classic “living wall” or privacy shrub fence. I however not once, despite all of the linear feet of fence there is to maintain, one person trimming back the wild gates of nature. So my question is who, when or how does all of this take place? Total forcefield automatically zaps any wayward branches is my guess. Like the dog zapper for plants.
