The Q&A Archives: How And When Do I Cut My Comfrey Plant?

Question: I have a booming comfrey plant in a container. I am growing comfrey for the allotonin content that I use for herbal skin remedies. This is the first time I have grown my own comfrey.
The flowers on the top three shoots are blooming off of one main stalk that is about 2 1/2 feet tall. There are leaves still growing around the main stalk. Will these create stalks of their own if I cut the main one?
Should I cut the main stalk to the soil or leave some leaves? If so, how many?
Please help in any way you can:-)

Answer: Comfrey is a hardy plant and grows so vigorously that it can overtake an area in a single growing season. Cutting your plant back will only encourage additional stem and leaf growth. Go ahead and cut away the flowering stalk. As you're harvesting, allow some leaves to remain near the soil level to help feed the roots. Although the plant will quickly replace any stems and leaves that are cut away, leaving a few will keep it producing for you. The allantoin content in comfrey is concentrated in the fastest-growing part of the plant. In winter, it will be concentrated in the root area (rhizome). In spring and summer allantoin will be concentrated in the leaves. Hope this information helps!
