I planted a row of American pillar arborvitae several years ago from 6" starting plants. Oaks and Eastern red cedars are the most prevailing tree species around so no wonder the arborvitae are doing well too. They have grown to very 10 ft tall while remaining narrow. I'd like to have more for wind breaking and privacy screening purposes. The patent has expired a few years ago so it's legal to grow them by asexual propagation. However, there seems to be few examples of rooting conifers in general. Has anyone successful grown coniferous trees from cuttings? What media to use? And how long does it take to root? Thanks!
