|Here in Southern California, my one-year old Hong Kong orchid tree (bauhinia) is finishing its bloom. Should I prune off the old flower stems?|
|It isn't necessary to prune off the old flowering stems, but you can thin out any crowded growth when blooming is finished. Your tree will have an umbrella shaped growth habit, reaching about 20' high and wide at maturity. Regular pruning is not necessary but you can certainly prune out errant growth, or anything that's overcrowded.
Enjoy your lovely tree!
