Ecological Benefits of Growing Comfrey
Let’s explore why comfrey deserves a prime spot in your permaculture garden.
Attracts Pollinators
When comfrey bursts into bloom with its enchanting blue, pink, purple, or white flowers, it turns into a bustling hub for pollinators. Bees, butterflies, and other beneficial insects flock to these nectar-rich blossoms, boosting biodiversity and aiding the pollination of your garden plants.
Provides Habitat for Beneficial Insects
Beneath comfrey’s expansive leaves lies a hidden world teeming with beneficial insects. These tiny allies help maintain ecological balance by preying on harmful pests, naturally safeguarding your garden without the need for chemical pesticides.
Fertilizes with Nutrient-Rich Mulch
Comfrey’s fast-growing foliage is a nutrient powerhouse, perfect for creating rich mulch or green manure. By using comfrey leaves as a natural fertilizer, you enrich the soil and promote the health and vigor of your garden plants.
Choosing the Right Comfrey Variety
When it comes to picking the right comfrey variety for your permaculture garden, knowing the distinct traits and benefits of each type is key.
True/Common Comfrey (Symphytum officinale) for Medicinal Uses
True or Common Comfrey, also known as Symphytum officinale, is celebrated for its medicinal properties and historical use in herbal remedies. Here are some highlights to consider if you’re thinking about cultivating True Comfrey:
- Medicinal Purposes: Often called ‘knitbone,’ True Comfrey has been traditionally used for healing external wounds, broken bones, and various ailments.
- Allantoin Content: This variety boasts high levels of allantoin, a compound known for promoting cell growth and healing.
- Propagation: True Comfrey spreads through seeds, making it a prolific grower. Regular maintenance is required to prevent it from overtaking your garden.
- Recommended Use: Ideal for medicinal gardens where leaves and roots are used to make herbal salves and poultices.
Russian Comfrey (Symphytum x uplandicum) for Biomass and Mulching
Russian Comfrey, especially the Bocking 14 cultivar, offers distinct advantages for biomass production and soil enrichment. Here’s what you need to know about this variety:
- Sterile Seed: Unlike True Comfrey, Russian Comfrey has sterile seeds, preventing unwanted spread. This makes it a reliable choice for controlled cultivation.
- Green Manure: It’s commonly grown for its nutrient-rich mulch and green manure, which enhance soil fertility and promote plant growth.
- Vigorous Growth: Known for its rapid growth rate, Russian Comfrey provides an abundant supply of leaves perfect for mulching and composting.
- Division: As the plant expands, periodic division is necessary to maintain its health and productivity.
Planting Comfrey
Explore the different methods for planting comfrey, including using root cuttings, mature plants, or seeds.
Planting Root Cuttings
- Preparation: Before diving into planting root cuttings of comfrey, it’s essential to soak them in water for about an hour. This step helps the roots acclimate to their new environment more easily.
- Planting Process: Dig a small hole of appropriate depth based on your soil type – 2 inches for clay soil or 4 inches for sandy soil. Lay the root cutting laterally in the hole and cover it with soil. Top it off with a nitrogen-rich mulch like manure, grass clippings, or clover. Don’t forget to water thoroughly to kickstart growth.
- Advantages: Planting root cuttings not only saves you money compared to mature plants but also simplifies the planting process due to the smaller hole required.
Planting Mature Plants
- Soil Preparation: Using a digging fork, loosen the soil where you plan to plant your mature comfrey. Dig a hole at least a foot deep, ensuring the soil remains loose enough for the plant’s roots to establish themselves firmly.
- Planting Depths: The size of the plant dictates the depth of the hole – the bigger the plant, the deeper you should dig. Incorporate nutrient-rich compost or manure during planting to provide a nutrient boost.
- Mulching: After planting, top the area with mulch to retain moisture and suppress weed growth, promoting a healthy environment for your comfrey to thrive.
Sowing Seeds
- True Comfrey: Sowing seeds is an option for growing true comfrey, allowing for ample space for the plants to spread over time. If you have the room and desire for a spread of comfrey, sowing seeds can be a rewarding method.
- Considerations: Keep in mind that comfrey is a prolific grower, and once established, it can spread readily. Ensure you have ample space and the willingness to let the plants propagate naturally.
The secrets to successful Cultivation
- Plant three plants in each square meter to cover the soil over time.
- The best times to plant are in the fall for strong roots or in the spring.
- This plant prefers moist, clay-like, or dense soil that is rich in organic matter.
- Mulch the soil to keep it cool. Spreading a little compost as mulch in the spring also helps feed the soil.
- Harvest the plant to use in your compost or as mulch. Regularly cutting its leaves throughout the season prevents it from spreading too much and promotes new growth.
- Control its growth by removing any shoots or flowers you don’t want to stop it from spreading seeds.
Harvesting Comfrey
- Optimal Harvest Time: To ensure the highest quality, harvest comfrey young leaves before they flower. The best months for harvesting are between May and September. During these months, the leaves contain a higher concentration of nitrogen, which is ideal for both gardening and cooking uses.
- Harvesting Technique: Cut the comfrey clump down to ground level to gather all leaves, stems, and flowers. This method allows the plant to regenerate quickly. Within a few weeks, new growth will appear, and the leaves will be ready for use again.
- Culinary Uses: If you’re using comfrey in the kitchen, it is mostly added to soups or eaten raw in salads. The leaves of comfrey have a distinctive iodized flavor, similar to that of borage flowers, adding a unique taste to dishes.
