My indoor Dracaena is getting too tall. I’d like to prune it, and maybe use the cuttings to start new plants. How do I do this?
You should be able to do both tasks. The Complete Houseplant Survival Manual by Barbara Pleasant (Storey, 2005) says “when plants become too tall, cut off the cane at any height. New leaf clusters will grow from just below where the cane was cut. You can cut sections into 6-inch pieces and root them like stem cuttings.”
You might also find this discussion from University of British Columbia Botanical Garden’s online forum useful.
Here is more information, from University of Florida, which describes how pruning will result in two or more branches forming where the pruning cut was made: “Cut one or two of the stems to a point where new foliage is needed.”
