Answer: Umbrella Pine (Sciadopitys verticillata) can be propagated by cuttings. According to Michael Dirr's "Manual of Woody Landscape Plants" the best times to take them are February-March and July-August. He mentions some helpful tips: the rooting seems to be tree-specific and some are just easier than others, soaking the cutting in water prior to rooting seems to be beneficial, January cuttings placed in half sand, half peat took five months to root, August cuttings took about eight months. The traditional IBA rooting hormone did not seem to make a huge difference in the success rate. Good luck with your project!
