Please Dont Prune

This is a juniper and junipers generally don’t respond well to pruning unless it’s done by a practiced professional. (And we don’t mean a mow-and-blow guy who comes in with a chain saw or electric trimmer.) To prune them correctly they should be cut back to individual crotches, removing entire limbs and preserving the natural shape of the shrub. These junipers will continue to get larger; they’re slow growers, but can easily reach 5-6 feet. It seems like you’re dissatisfied with the size of many of your trees and shrubs which indicates either that you moved into a house with existing landscaping or that someone planted these without knowing what their ultimate size would be. Maybe you should remove them and plant something that will stay closer to the size you want.
