How to Produce Comfrey Plugs
Discover how to grow, prepare, and sell comfrey plugs as a profitable business opportunity. This guide covers everything from propagation techniques to marketing strategies.
The Business Opportunity
Producing comfrey plugs offers an excellent business opportunity with low startup costs and high profit potential. Comfrey plugs are small, established plants grown in cell trays that are ready for transplanting, making them appealing to gardeners who want quick results without the uncertainty of growing from root cuttings.
The market for comfrey plugs continues to grow as more gardeners recognize comfrey's benefits for permaculture, organic gardening, and sustainable agriculture.
Why Comfrey Plugs?
- Higher value product: Plugs sell for $3-8 each, offering better margins than root cuttings
- Customer preference: Many gardeners prefer the convenience and reliability of established plants
- Scalable production: Can be produced in large quantities in a small space
- Extended selling season: Can be sold during the entire growing season

Setting Up Your Production Area
A successful comfrey plug operation requires a proper setup that provides optimal growing conditions. Unlike field production, plug production typically occurs in a more controlled environment.
Location Requirements
- Protected area: Greenhouse, hoop house, or sheltered outdoor area
- Light: Access to bright, indirect light (direct sun can overheat plugs)
- Water access: Reliable water source for regular irrigation
- Work space: Area for preparing trays, potting, and handling plants
- Storage: Space for supplies and finished plugs
An efficient plug production setup with proper spacing and irrigation
Essential Equipment
Plug Trays
50-cell trays are ideal for comfrey plugs, providing adequate space for root development
Propagation Tables
Raised surfaces to hold trays at a comfortable working height with good drainage
Irrigation System
Mist system, drip irrigation, or hand watering setup for consistent moisture
Climate Control
Fans, shade cloth, and/or heating mats to maintain optimal growing conditions
Propagation Methods
Comfrey plugs can be propagated through several methods, with root cuttings being the most common and reliable for commercial production.
Root Cutting Method
Source Root Material
Harvest roots from established Bocking 14 comfrey plants. Thicker roots (pencil diameter or larger) work best but smaller roots can also be used.
Prepare Root Cuttings
Cut roots into 1-2 inch sections. Make clean cuts perpendicular to the root length. Each cutting should be at least 1/4 inch in diameter.
Prepare Plug Trays
Fill plug trays with a well-draining potting mix. A mix of 60% peat or coco coir, 30% perlite, and 10% compost works well.
Plant Root Cuttings
Place one root cutting horizontally in each cell, about 1/2 inch below the surface. Ensure good soil contact around the cutting.
Water and Maintain
Water thoroughly and place in a warm location (65-75°F). Keep soil consistently moist but not waterlogged.
Alternative Propagation Methods
Crown Division Plugs
Small sections of crown with 1-2 buds can be planted directly into plug trays. These establish quickly but require more initial plant material.
Growing and Maintenance
Proper care during the growing phase ensures healthy, marketable plugs and maximizes your production efficiency.
Development Timeline
| Phase | Timeline | Key Tasks |
|---|---|---|
| Sprouting | 2-4 weeks | Maintain consistent moisture and warmth until leaves emerge |
| Early Growth | 4-6 weeks | Begin light fertilization, ensure adequate light |
| Establishment | 6-10 weeks | Regular fertilization, monitor for pests, begin hardening off |
| Market Ready | 10-12 weeks | Fully rooted plugs with 3-5 leaves, ready for sale |
Watering
- Keep soil consistently moist during sprouting phase
- Once established, allow slight drying between waterings
- Water at the base to avoid leaf diseases
- Consider a mist system for early stages
Fertilization
- Begin fertilizing when first true leaves appear
- Use half-strength organic liquid fertilizer every 2 weeks
- Comfrey tea makes an excellent self-sustaining fertilizer option
- Avoid over-fertilization which can lead to leggy growth
Light Management
- Provide bright, indirect light
- Use shade cloth (30-50%) during summer months
- Rotate trays regularly for even growth
- Supplemental lighting may be needed in winter
Pest & Disease Management
- Monitor for aphids, slugs, and snails
- Ensure good air circulation to prevent fungal issues
- Remove any diseased plants promptly
- Use organic pest management methods
Packaging and Marketing
Effective packaging and marketing are crucial for maximizing sales and commanding premium prices for your comfrey plugs.
Packaging Options
- Individual containers: Small pots or cells for retail sales
- Multi-packs: 4, 6, or 9-packs for gardeners planting multiple plants
- Bulk trays: Full or half trays for landscape customers or retailers
- Eco-friendly packaging: Biodegradable pots or recycled materials to appeal to environmentally conscious customers
