Tricking the branches of flowering trees and shrubs into blooming early, a practice known as “forcing branches,” is a beautiful and colorful way to showcase the budding promise of warmer days.
Almost any bloomer can be forced at anytime, says Phil Mueller, of Star Valley Flowers in Wisconsin, which ships woody ornamentals to florists and major retailers.
