How to Harvest Comfrey
Comfrey is a perennial plant that propagates easily from root divisions. It is often grown in medicinal gardens or for use as a natural fertilizer. Comfrey has been used for over 2,000 years in Chinese medicine to heal wounds and bones. It can be found in ointments, decoctions, poultices and pastes to help sprains, burns and inflammation. Comfrey is also high in nitrogen and can be used to fertilize your garden. Comfrey has a high yield, and you can harvest your plant several times throughout the growing season.
Wait for your comfrey to begin forming flower heads, when it is about 2 feet tall, to start harvesting your leaves for the first time.
Put on you gloves to protect your hands. Comfrey can irritate your skin.
Use your pruning scissors to cut each stem of your plant down so it is about 2 inches high. Cut stems at a slight slant.
Water your comfrey plants immediately after harvest. Add mulch to the soil around each plant.
Wrap the comfrey you have harvested into half-inch thick bundles by wrapping a rubber band around the end of the stems. Hang your bundles upside down in a warm and dark place to dry.
Repeat harvesting your comfrey every four weeks until September by cutting it down to 2 inches in height. Your plants will propagate themselves from the roots in the fall, or you can cut off pieces of the root and replant them in another spot.
Rid Of Comfrey
Uproot as much comfrey as possible by hand and place it in a black plastic bag. Mix together 1 cup of an herbicide containing the following active ingredients with 1 gallon of water in a garden sprayer: 20.46 percent glyphosate, 0.89 percent diquat, and 0.089 percent indaziflam. If experiencing drought conditions, spray the treated area with water until wet. Apply the glyphosate a second time, if needed. Wait six months before replanting in the treated area. Pull as much comfrey as you can by hand or cut it to ground level with a weed trimmer or mower. You can also insert wood stakes through the mulch to pin it to the ground. Remove the mulch if it killed the comfrey, and rake the detritus for disposal.
