Propagating Viburnum obovatum "Walter's Viburnum"
"How do I propagate Walter's viburnum (Viburnum obovatum)? I have received this question a few times as an agent and I thought it would be a good time to finally post a blog article on it. In 1989 an article was published by UF's Dr. Bijan Dehgan in the Florida State Horticulture Society Proceedings entitled "Vegetative Propagation of Florida Native Plants: III Shrubs" He looked at the cutting propagation of ten native shrubs over 5 different times of the year with three different treatments of hormones. One of the plants was the Walter's viburnum. The cuttings for the viburnum were taken from Polk County (Four Corners Mine). He took terminal semi-hard wood cuttings. The hormones were 0, 2500, and 5000 parts per million of IBA in a quick dip. Cutting times were March, May, July, September and November. Over all the combinations it seems that the best time was May with 5000 ppm IBA which yielded 75% rooting. Zero and 2500 IBA yielded 61% and 64% respectively. September cuttings with 5000 ppm IBA yielded 60% rooting. Here is a link to the original publication. http://tiny.cc/vobovatum
I have also read on Floridata that fast growing shoots in the spring root easily, but there was nothing else mentioned. Let me know how it goes or let me know how your success is at propagating this plant.
