WHEN TO TRIM SHRUBS

The most common question about shrub trimming is: "When?"
  
With flowering shrubs, the easiest "rule of thumb" to remember is to always trim shrubs within one month after they finish blooming - this way you don't risk removing next year's blossoms.

Trimming at the "Right Time"

Cutting shrubs back

The most severe cutting-back of shrubs is best done in early spring, just prior to the emergence of new growth. We've had success rejuvenating large Yews, Junipers, Rhododendrons, and many other varieties during this early-season timeframe.
   

"Candle" well describes the new growth on Mughos and other Pines (photos above and below). 1/2 to 2/3 of each new candle should be trimmed off after the candle fully elongates, but before the needles elongate - this is usually during June in SW Pennsylvania.  Using these methods will keep your pines compact and well shaped.
