What are the best and worst times of year to prune a cedar hedge in the Vancouver area? I have a 10' hedge in front of my house that needs a trim, but I've heard that if the weather is too warm, pruning will kill it.
No, it won't. Shearing in midsummer is good because it will have time to grow back a bit before winter, but shouldn't become ragged--unless you are keeping it very tight. The "dieing" during warm weather you heard about was probably the burning of shaded, interior foliage resulting from the cutting away of all the outer growth. To avoid this don't cut that far back.
