Planting Your New Comfrey Crowns Cuttings

We suggest planting* new comfrey cuttings as soon as possible. If you are unable to plant right away, keep paper towels moist. 

  1. Dig a small hole - just a few inches, large enough to bury your comfrey cutting.
  1. Place the sprouted end up (the end sticking out of the paper towel wrap) in the hole.
  1. Cover with soil. You may bury the budding point with soil - up to 4 inches deep. Some people prefer to leave the tip of the sprout peeking out of the soil - either method works. 
  1. Water lightly and keep the soil moist - not wet - until you see visible new growth.
  1. You should see visible top growth 2 to 8 days after planting.
  1. When the leaves are at least 2 feet tall, use a garden knife or shears to cut them down to a couple of inches above the soil. Harvest the outer leaves first so the plant can continue growing.

*Comfrey does best planted directly in the ground. You can keep it alive and fairly happy in a pot for several months, but ultimately it will want to send its roots deep into the soil.

Comfrey in the Permaculture or Regenerative Garden:

Comfrey is an essential plant for any permaculture garden due to its unique ability to accumulate nutrients from deep within the soil and bring them up to the surface where they can be used by other plants. Comfrey leaves are packed with nitrogen, potassium, and phosphorus, making it an ideal plant for use as a natural fertilizer. Additionally, the deep roots of comfrey help to break up compacted soil, improving soil structure and allowing for better water retention. Comfrey also attracts pollinators and beneficial insects, making it a valuable companion plant in any garden. Its fast growth and high yield make it an efficient source of organic matter and mulch, which can help to suppress weeds and retain soil moisture. Overall, comfrey is a must-have plant for any permaculture garden due to its ability to improve soil fertility, promote biodiversity, and support the growth of other plants.

Here are some ways to use Comfrey in the Regenerative and Permaculture Garden:

  • Chop-and-drop leaves as a nutrient-rich mulch or green manure to improve soil fertility
  • Chopped and added to compost to speed up the decomposition process
  • Planted in the vicinity of fruit trees and vegetables to enhance their growth and productivity.

Comfrey is an incredible plant with many uses in the garden as well as the herbal medicine chest. It’s easy to propagate from crown divisions and root cuttings.
