What are some trees and shrubs with branches suitable for forcing indoors in the winter?
Cut the branches of forsythia, spirea, spicebush, quince, pussywillow and other early blooming trees and shrubs for forcing indoors. If you can keep them in a cool place and change the water at least once a week they will last longer and you will be rewarded with beautiful blooms for a few weeks. Try spacing your cuttings at two-week intervals so you will achieve a continual succession of flowering, thereby extending the indoor display well into late winter.
