How to Produce Comfrey Crowns
Discover how to grow, harvest, and sell comfrey crowns as a profitable business opportunity. This guide covers everything from establishing parent plants to marketing your finished product.
The Business Opportunity
Producing comfrey crowns offers an excellent business opportunity for gardeners and small-scale farmers. Comfrey crowns are in high demand among gardeners, herbalists, and sustainable agriculture enthusiasts for their ability to quickly establish new plants.
As a perennial plant that can live for 20+ years, comfrey provides recurring harvests of both crowns and other products, creating multiple revenue streams from a single planting.
Why Comfrey Crowns?
- High profit margin: Comfrey crowns can be sold for $5-15 each, while costing very little to produce
- Renewable resource: A single parent plant can produce multiple crowns annually
- Year-round sales potential: Crowns can be sold during dormant seasons when other farm income may be limited
- Low startup costs: Begin with just a few parent plants and expand gradually

Establishing Parent Plants
The foundation of a successful comfrey crown business is healthy, vigorous parent plants. Bocking 14 is the preferred cultivar for commercial production due to its sterility (preventing unwanted spread) and high content of beneficial compounds.
Selecting Your Growing Site
Choose a location with these characteristics:
- Soil: Well-draining, fertile soil with pH 6.0-7.0
- Sun exposure: Full sun to partial shade
- Space: Allow 3-4 feet between plants (they will spread)
- Accessibility: Easy access for maintenance and harvesting
Sourcing Initial Stock
Begin with certified Bocking 14 comfrey plants from a reputable supplier. Starting with 10-20 plants provides enough stock to begin crown production within 1-2 years while keeping initial investment manageable.

Planting Process
Prepare the Soil
Incorporate compost or aged manure into the soil before planting. Comfrey has deep roots that benefit from loose, fertile soil.
Dig Planting Holes
Create holes approximately 12 inches deep and wide enough to accommodate the root system without bending.
Position Plants
Place comfrey crowns or root cuttings with the growth buds facing upward, with the top of the crown about 1-2 inches below soil level.
Backfill and Water
Fill in with soil, gently firm around the plant, and water thoroughly to eliminate air pockets and help establish root contact with the soil.
Mulch
Apply 2-3 inches of organic mulch around plants (but not touching the stems) to suppress weeds and retain moisture.
Growing and Maintenance
Comfrey is a low-maintenance crop once established, but proper care ensures maximum crown production and plant longevity.
Watering
- Water deeply during establishment and dry periods
- Once established, comfrey is drought-tolerant but produces more with consistent moisture
- Avoid waterlogged conditions which can cause root rot
Fertilization
- Apply compost or balanced organic fertilizer in early spring
- Top-dress with compost after each major harvest
- Avoid high-nitrogen fertilizers which promote leaf growth over crown development
Weed Management
- Keep area weed-free, especially during establishment
- Use mulch to suppress weeds
- Once mature, comfrey's dense growth naturally suppresses weeds
Pest and Disease Management
- Comfrey has few pest problems
- Watch for slugs and snails on young plants
- Ensure good air circulation to prevent fungal issues
Seasonal Care Schedule
Season | Tasks |
---|---|
Early Spring | Remove dead leaves, apply compost, divide plants if needed |
Late Spring | First leaf harvest (if also harvesting leaves), monitor moisture |
Summer | Additional leaf harvests, maintain adequate watering |
Fall | Final leaf harvest, prepare for crown division if desired |
Winter | Plants dormant, good time for crown harvesting and division |
Harvesting Techniques
Harvesting comfrey crowns requires careful timing and technique to maximize yield while ensuring the health of parent plants. The best time to harvest is during the dormant season (late fall through early spring) when the plant's energy is stored in the roots.
Optimal Timing
- Plant age: Wait until plants are at least 2-3 years old before first major crown harvest
- Season: Late fall after foliage dies back or early spring before new growth
- Frequency: Harvest from established plants every 2-3 years for maximum crown size
- Weather: Choose a day when soil is not frozen or waterlogged
Step-by-Step Harvesting Process
Prepare the Area
Water the soil a day before harvesting if it's dry to make digging easier. Clear away any dead foliage to expose the crown area.
Dig Around the Plant
Using a garden fork or spade, dig in a circle around the plant about 8-12 inches from the center, going down at least 12 inches to avoid damaging the deep roots.
Lift the Root Mass
Gently leverage the plant upward, working from multiple sides to loosen the root mass. Avoid pulling directly on stems as they may break.
Divide the Crown
Once lifted, shake off excess soil and examine the crown structure. You'll see multiple growth points that can be separated into individual crowns.
Replant Parent Stock
Immediately replant a portion of the crown with 3-5 buds to maintain your parent plant. Water thoroughly after replanting.
Essential Harvesting Tools
Garden Fork
Preferred for initial loosening of soil around plants without cutting through roots
Sharp Knife or Pruners
For clean cuts when dividing crowns
Gloves
Comfrey leaves can irritate skin; sturdy gloves protect hands during harvesting
Containers
Buckets or trays to hold harvested crowns
Processing and Preparation
After harvesting, proper processing ensures your comfrey crowns remain viable and attractive to customers. This stage is critical for product quality and shelf life.
Processing Workflow
Initial Cleaning
Gently rinse harvested crowns to remove excess soil. Use a soft brush if necessary, but avoid damaging the buds. A shallow water bath works well for this step.
Inspection and Sorting
Examine each crown and sort based on size and quality. Look for healthy buds and discard any showing signs of rot or damage. Categorize into premium and standard grades if selling at different price points.
Trimming
Trim any remaining leaves or stems to about 1-2 inches above the crown. Trim excessively long roots to about 4-6 inches, making clean cuts with sharp pruners.
Curing
Allow crowns to air-dry in a shaded, well-ventilated area for 24-48 hours. This helps heal cut surfaces and reduces moisture before packaging.
Final Inspection
Before packaging, perform a final quality check to ensure all crowns meet your standards. Remove any that show signs of deterioration during the curing process.
Quality Standards for Marketable Crowns
Characteristic | Premium Grade | Standard Grade |
---|---|---|
Size | 3+ inches diameter | 1.5-3 inches diameter |
Visible Buds | 5 or more | 2-4 |
Root Structure | Well-developed, multiple roots | Basic root system present |
Appearance | Clean, no damage | Minor imperfections acceptable |
Packaging and Storage
Proper packaging and storage are essential for maintaining crown viability and creating an appealing product for customers. Your packaging should protect the crowns while showcasing their quality.
Packaging Materials
- Primary packaging: Breathable materials like paper bags, burlap, or mesh bags
- Moisture control: Small amount of slightly damp sphagnum moss or wood shavings
- Labels: Waterproof labels with your brand, planting instructions, and variety information
- Shipping materials: Sturdy boxes with cushioning for mail orders
Storage Guidelines
Properly stored comfrey crowns can remain viable for several weeks to months:
- Temperature: Store at 32-40°F (0-4°C) for extended storage
- Humidity: Maintain 80-90% relative humidity
- Air circulation: Ensure adequate ventilation to prevent mold
- Duration: Optimal storage is 2-4 weeks; can extend to 2-3 months under ideal conditions
- Inspection: Check regularly for signs of sprouting or deterioration
