Proper pruing of red twig dogwoods
I moved into a house with a landscaped front yard which includes 5 large variegated red twig dogwood shrubs. They are about 8 feet tall. I'd like to know how much I can prune them back-I've heard everything from pruning them back to the ground to promote new growth to pruning them down to 2/3rds of their present height. I'd like to keep the shape, just shorten them a few feet! I've already pruned the dead/some older brances to the ground. Any suggestions would be great!!
