Is is possible to treat a live cedar branch with rooting hormone and have it take root? The tree it was removed from was uprooted in a storm. The tree has sentimental value, so I would appreciate any suggestions how to proceed. The branch is standing in water, has several cones and new green needle growth.
Sorry, no, cedars won't root from cuttings. You could try getting the seeds out of the cones and see if you can germinate any of them. Soak the cones in ice-cold water for 3 or 4 days, then break the top off with a hammer, and pull apart the scales by hand; there are two seeds on each scale. With cultivated cedars, typically only a small proportion of the seeds will be viable; the viable seeds are plump, about 1.5cm long with a 2-3cm long seedwing.
