|I have dwarf Mugo pines in my garden that have an average height of 1 1/2'. They were probably palnted in 1994 when the house was built. They seem to be shooting up this year. Is there a way to safely prune them back and what time of year is best?

|It's better to cut off all or some of the new growth (called candles) as they are developing in the spring. This will retard new growth. Mugo pines will not develop new needles if you prune back to bare wood so don't cut them back too far. I usually prune off about a half to two thirds of the length of the candles each spring. Best wishes with your Mugo pines.
