It’s great to hear that the article has been of good use, thank you for the feedback. As for propagating a Mass Cane stalk from the existing canes, yes it is possible but the results will likely be disappointing if a new full cane is expected, and there is a big risk in damaging the existing Canes. While it is possible, I would not recommend it, the risk and effort involved will be greater than the return. I have however seen leaf crown cuttings propagated after a Dracaena has been trimmed. This will create a small foliar plant. That kind of start from a stem cutting carries little risk and would create more of a tabletop indoor plant if successful. If the smaller cuttings sound like what you would want, begin by getting more information on starting root cuttings for Dracaena probably using root hormones. If you do plan on attempting trying a root cutting I would do it in spring, or the milder summer months in which the most consistent temperatures and sunlight are available.
