Did you know comfrey is one of the easiest perennial plants to propagate? Unlike many herbs that rely on seed, comfrey grows vigorously from pieces of root. Both root cuttings and crowns are a reliable way to establish new plants, giving you two options for propagating.
Root Cuttings vs Crowns
Sometimes these two terms are used interchangeably…but there is a slight difference between the two.
Root Cuttings: These are small sections of comfrey root that will sprout new growth when planted correctly. Even short pieces can produce a full plant under the right conditions.
Crowns: These are the upper portion of the root where new shoots emerge. Crowns tend to establish more quickly, especially in cooler or less ideal conditions.
How to Plant Root Cuttings and Crowns
To plant root cuttings or crowns, choose a location with full sun to partial shade and well draining soil. While comfrey is very adaptable, it thrives in soil that has been loosened and amended with compost. Plant root cuttings horizontally or slightly angled beneath the soil surface, while crowns should be planted with the growing point just at or slightly below soil level.
For a visual demonstration, here is a great video by Kaylee with Honeystead on how to propagate comfrey from cuttings.
Watering and Establishment
Water newly planted cuttings well and keep the soil consistently moist during establishment. In most cases, new shoots will appear within a few weeks. Once established, comfrey becomes very drought tolerant thanks to its deep root system.
Long Term Growth and Management
Because comfrey regenerates so readily from root pieces, even small fragments left in the soil can grow into new plants. This is one reason why gardeners often prefer purchasing root cuttings or crowns rather than seed, as it ensures consistent growth and known plant characteristics.
With proper care, propagated comfrey plants can be harvested multiple times per season and will continue producing for many years.
ORDER COMFREY
Disclaimer: Comfrey is not recommended to take internally, because it contains pyrrolizidine alkaloids (PAs), which are linked to liver toxicity and possibly cancer.
