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.
- Dig a small hole - just a few inches, large enough to bury your comfrey cutting.
- Place the sprouted end up (the end sticking out of the paper towel wrap) in the hole.
- 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.
- Water lightly and keep the soil moist - not wet - until you see visible new growth.
- You should see visible top growth 2 to 8 days after planting.
- 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.
