: i have 8 evergreen bushes; they were originally part of the christmas plantings in Rockerfeller Center over 25 years ago. After being removed they were planted in my yard and maintained well. I MUST CUT THEM BACK! I will be cementing my front yard for parking space in the next year.
"When is the best time to cut them back?" The best time to cut back depends on the shrub. If it flowers in the spring, cut back after blooming. If it flowers in the fall, cut back after bloom or early spring. If you cut them too late in the fall and they get a growth spurt, the new growth won't have time to harden off before frost and could get damaged.
"should it be done gradually or done all at once?" That depends on how much you want to prune them. Generally it is recommended to only prune 1/3 of the shrub at a time. That would be a 3 year project. Do you know which shrubs you have?
Here's some sites that might be helpful.
Hope this helped.
