Care Instructions
Caucasian comfrey prefers moderate temperatures and indirect bright light. It thrives in environments with moderate humidity and should be watered regularly to keep the soil evenly moist. Avoid letting the soil dry out completely.Soil
This plant prefers loamy soil that is well-draining yet retains moisture. A rich, fertile soil with good organic content will support its growth. Ensure the soil is kept consistently moist but not waterlogged.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks, to support its vigorous growth.Repotting
Repot Caucasian comfrey every 2-3 years or when it outgrows its container. Choose a slightly larger pot with good drainage, and refresh the soil to provide new nutrients. Repotting is best done in early spring before the growing season begins.Propagation
Propagate by division in early spring or late autumn. Carefully dig up the plant and separate the root clumps, ensuring each division has roots and shoots. Replant the divisions in prepared soil and water thoroughly.Pruning
Prune the plant to remove dead or damaged leaves and spent flowers. This encourages new growth and maintains the plant's shape. Pruning is best done in late winter or early spring before new growth starts.Toxicity
Symphytum caucasicum is generally non-toxic to pets and humans. However, it is always advisable to prevent pets and children from ingesting any plant material.Additional
Caucasian comfrey is often used as a ground cover due to its dense foliage and rapid growth. It can also be used in permaculture as a dynamic accumulator, helping to improve soil fertility.REVOLUTIONIZE YOUR PLANT CARE
