I transplanted some balsam flowers from a neighbor's yard two weeks ago and they seem very happy where they are now. Since we don't have great soil (mostly rock), I want to encourage growth and hopefully have them multiply. At many of the joints in the stems, there are very healthy-looking protuberances that look like roots. Can I cut up the stem and plant these sections separately? Or can I lay the whole stem down across the soil, without uprooting the plant and let roots do as they will? Forgot to say that these balsams are five to seven feet tall. I have posted an image of the flower head.
